Ultrasonication Extraction of PHA from Haematococcus sp. for Bioplastic Application [BT01]
By Assoc. Prof. Chm. Ts. Dr. Wong Yee Ching

Petroleum-based plastic has been extensively used over the years in industries for its desirable properties which are durability, flexibility, lightweight, and resistance towards degradation. However, these properties have caused the accumulation of one-time usage plastics which give rise to other environmental problems such as the depletion of fossil resources, consumption of plastics by aquatic life, carbon dioxide emission from incineration, soil contamination, and chemical released in the ocean. The bioplastic production from starch, waste biomass, and bacterial fermentation has been done to substitute the petroleum-based plastic production. However, the sources are non-compatible due to a lack of structure variability, pose threat to food security, and high production cost. Therefore, this study was focussing on bioplastic made up of extracted polyhydroxyalkanoates (PHA) from Haematococcus sp. by sonication method for application in bioplastic. The research was divided into cultivation of microalgae, extraction of PHA, and characterization of bioplastic film. The centrifugation of microalgae was done after 14 days of open-system cultivation. The extraction of PHA was done by using a sonicator at 37 kHz, followed by purification using cold methanol and bioplastic film casting using carboxymethyl cellulase (CMC), extracted PHA, and water. The presence of PHA in Haematococcus sp. was studied using Gas Chromatography-Mass Spectrometry (GCMS). The characterization of bioplastic consisted of Fourier-transform infrared (FTIR) analysis and biodegradable test. The functional group found in FTIR is related to the presence of PHA in the bioplastic and the biodegradability test proved the degradability properties stated in the past study which will encounter the problems and alternative solution for petroleum-based plastics.

By Mrs. Normazzaliana Ibrahim

Protease is one of the important enzymes and has been utilized in numerous industrial application. Due to its wide application, till date research on protease is continuously studied. Thermostable alkaline protease 50a gene isolated from Bacillus subtilis was cloned into expression plasmid pGEX4T-1 and transformed into Escherichia coli BL21 and Top10. The positive clones harboring the gene were selected based on the formation of clearing zones on Luria-Bertani skimmed milk agar plates and further confirmed through polymerase chain reaction using specific primer. The expression of thermostable alkaline
protease 50a in E. coli BL21 and Top10 were induced by 0.5mM IPTG and incubated for 24 hours at 200 rpm. The expression of protease was discovered to happen intra and
extracellularly with intracellular expression yielded higher level of protease enzyme. The enzyme activities in E. coli BL21 were found to be 31.33 U/mL intracellularly and 12 U/mL extracellularly. Meanwhile in E. coli Top 10, intra and extracellular expression yield 12.67 U/mL and 9.67 U/mL respectively. The purification of protease gene through heat treatment increased the yield of purified protease by 2.5 fold for E. coli BL21 and 7.2 fold for Top10.
The findings revealed that E. coli BL21 was found to be a better host for the expression of protease 50a as compared to E. coli Top10.

Degradation Kinetics of Ammonia Nitrogen in Aqueous Solution by Ozonation Treatment under Different Parameter Conditions [BT07]
By Miss Nur Zafirah Binti Mahyun

The efficiency of the ozonation process as disinfection and degradation for nitrogen ammonia in freshwater fishpond was investigated. The ammoniacal nitrogen (NH4-N) from synthetic wastewater and actual aquaculture wastewater from Nile tilapia fishpond were undergone ozonation process at different parameter effects. The effect of ozone dose (1.0 – 2.0 mg/L) and initial pH (2 – 12) on ammonia removal were studied through the batch ozonation process at ambient temperature for 4 hours. The highest removal in ammoniacal nitrogen was pH 10 (32% reduction) at 2.0 mg/L of ozone dose. The highest removal of ammonia nitrogen in aquaculture wastewater was 42% at pH 12 and 2.0 mg/L of ozone dosage. These findings suggest that the ozonation process could be effectively used to remove ammonia nitrogen from aquaculture wastewater and boost the biodegradability of recalcitrant organic compounds.

Harvesting of Freshwater Microalgae, Arthrospira sp. using Flocculation Method [BT15]
By Miss Aimi Alina Binti Hussin

Microalgae species, specifically Arthrospira platensis, is well-known and widely used as a protein and vitamin supplement to an aquatic organism and a complementary dietary ingredient. Efficient biomass recovery or harvesting of different algal species is nevertheless a vital bottleneck for large-scale biorefinery processes. As chemical has been widely recognised for its high-efficiency, cost-effective and scalable flocculation process, chemical flocculation was performed to harvest the biomass production of the microalgae. In the present study, the study of flocculation was conducted via three chemical flocculants: chitosan, aluminium sulphate, and copper (I) chloride in hydrochloric acid. The harvesting using flocculation was performed and optimised using one factor at a time (OFAT) and found that chitosan was the most effective flocculant achieving 94.62% flocculation efficiency using 50 mg/L dosages while the settling time taken to achieve above 80% efficiency can be observed at the first 5th minute and remained constant until the 60th minute of the experiment. Furthermore, chitosan was studied as a biodegradable polymer and non-toxic coagulant, which may be less harmful than other chemicals.

Cultivation of Marine Microalgae, Nannochloropsis sp. in different Photobioreactor System [BT17]
By Miss Nur Fakhira Binti Mohd Asri

Oil production from microalgae may be more effective, leaving a smaller environmental footprint and avoiding competition for arable land or biodiverse ecosystems. Present algae cultivation systems and lipid induction methods, on the other hand, need to be significantly enhanced and are in danger of being contaminated by other algae or algal grazers. The cultivation system for the current indoor bioreactor is expensive due to its material. Closed culture systems (photobioreactor type) have high production and maintenance costs, and open culture systems have contamination issues, resulting in lower productivity. This study focuses on cultivating microalgae using the contemporary design of an airlift loop photobioreactor with a draft tube in the middle of it and will use a cheaper material (autoclavable polycarbonate material). The cultivation optimisation of Nannochloropsis sp. was carried out at a different photobioreactor system, different aeration rate, light concentration, and inoculum concentration. The best growth performance was in a macro-bubble column system with 27.09 × 106 cell/mL and using a 0.9 L/min aeration rate that produced a maximum of 37.02 × 106 cell/mL of algal biomass. Moreover, the microbubble column system shows a 26.70% improvement as compared to an airlift loop system. For light concentration, the best growth performance was at 3000 lux, with a dry cell weight of 0.211 g/mL. The optimized growth condition with inoculum concentration of 15% v/v by having a maximum cell concentration of 27.36 x 105 cell/mL of algal biomass. Thus, from these studies, the set-up of a low-cost reactor can quickly be commercialised. Every feature, mainly the material used, is cheap and suitable (autoclavable) for the indoor cultivation of microalgae.

By Ms. Nur Syafiqah Rusli

Electronic cigarette (EC) a battery powered device which is capable to convert liquid into vapour was invented as an alternative to conventional smoker’s device. The liquid (e-liquid) in EC commonly contains carrier solvents, flavourings, and nicotine. The main carrier solvents such as propylene glycol (PG) and vegetable glycerine (VG) are known as the primary ingredient in the e-liquid. This study focused on the functional group for the main ingredient of e-liquids, PG, and VG. Here, to achieve this study's objective, Attenuated Total Reflectance – Fourier Transform Infrared (ATR-FTIR) spectroscopy has been used. The fitting process for PG and VG infrared spectra was performed using Origin 2019b software. The analysis revealed that PG and VG mainly content with O-H, C-H, and C-O groups, and its FTIR signal appeared at 3302 cm-1, 3268 cm-1, 2877 cm-1,1036 cm-1, and 1028 cm-1 of wavenumber, respectively. In this case, the hydroxyl or free radical compounds, O-H, C-H, and C-O, could be contributed a great potential of harm to human health. In this context, O-H can lead to multiple diseases such as respiratory disease and cardiovascular disease. In addition, C-H in vapour form can cause damage to the kidney or liver organ. In conclusion, all functional groups could be contributing to hazardous and toxicity effect towards the human body system. Therefore, exceeding inhalation above the limitations limit recommended of these chemical compounds in PG and VG subsequently will affect the e-cigarettes smokers' health.

By Dr. Mardawani Mohamad

In this study, the tannic acid compound from Brucea javanica sp was extracted by using conventional and non-conventional method, ultrasonic-assisted extraction (UAE). Tannic acids are based of flavonoid compound with antimicrobial properties that usually used as astringent to protect irritation effect on the skin. In conventional extraction, there are two parameters studied namely; extraction time (4, 6, and 8 hours) and temperature (30℃, 40℃, 50℃ and 60℃). From the obtained results of conventional extraction, the optimum yield of tannic acid was found at 6 hours of extraction time with temperature of 50℃ was 0.1527 mg/mL. Ultrasonic-assisted extraction is a green technology, which expected to extract tannic acid in shorter time, high extract yield and eco-friendly extraction technologies. Two parameters studied namely; sonication time (15, 30 and 45 minutes) and duty cycle (25, 50 and 75 %). For the extraction of tannic acid using ultrasonic-assisted extraction method (UAE), the optimum conditions obtained are 30 minutes of sonication time and 25% duty cycle for ultrasonic-assisted extraction method (UAE) with the concentration of 0.2313 mg/mL. The band spectrum for FTIR analysis that presented in pure sample and extracted sample show the similar pattern that represented by the functional group of anhydride and carbonyl stretching vibration. In conclusion, the extraction yields of ultrasonic-assisted extraction method (UAE) are higher than conventional extraction method. From the findings, it was proven that UAE is a significant method for tannic acid extraction from Brucea javanica sp.

The effect of detergent ingredients on the stability of thermostable alkaline protease 50a in the formulation of stain remover   [BT04]
By Assoc. Prof. Dr. Noor Azlina Ibrahim

New detergents approach such as pre-dosed liquid and powder as pre-treatment to enhance cleaning efficiency has received great interest among consumers and is becoming a trend in the laundry industry. The formulation of detergents is continuously developed to improve cleaning efficiency and to adapt to and fulfill market demands. In this study, four liquid stain remover formulations containing 50a protease as an additive were developed. The developed stain remover formulations were specifically designed to remove proteinaceous stains on fabrics. The properties of each formulation were assessed via its physical appearance and pH. Azo-casein assay was also performed to evaluate the stability of 50a protease in each formulation. The results obtained show that the 50a protease lost more than 50% of its activity after one week of incubation in these four formulations.  This indicates that detergent ingredients greatly affect the activity of 50a protease. The outcomes of this study could provide additional insights on the effect of detergent ingredients on 50a protease activity.

Antifungal Activity of Singgora Roof Tile with Titanium Dioxide (TiO2) Addition [BT13]
By Miss Nur Anis Syafira Bt Abdullah

The Singgora roof tile or usually called clay roof tile was used widely in traditional Malay houses. The clay itself has a high moisture absorption rate which makes it an ideal habitat for the growth of fungi. Therefore, the addition of the antifungal agent into the clay can inhibit the growth of fungi. To investigate the effect of antifungal, the fungi (Penicillium sp., Aspergillus sp., and Cladosporium sp.) obtained from old Singgora roof tile were cultured using Potato Dextrose Agar (PDA) as the nutrient medium. The single colonies were subculture into the new medium and observe the sporulation growth for antifungal susceptibility testing. Six paper discs were distributed evenly on the medium representing each different TiO2 weight percentage (0,5,10,20,25,30 wt.%). The discs were immersed in different concentration TiO2 solutions. Observation after 24 hours incubation the optimum antifungal agent for fungi inhibition was at 10 wt.% of TiO2 with Zone of Inhibition (ZOI) reached up to 4mm.  The surface morphology of the sample also shows the pore size increases as the sample composition increases. In addition, 10 wt.% TiO2 is the best composition to inhibit the growth of fungi as well as having good physical and morphological properties. More composition TiO2 added more quality to the Singgora roof tile. The addition of TiO2 as an antifungal agent into clay roof tile also shows the improvement in the characterization of the tiles sample.

Extraction of Crude Enzymes from Spent P. ostreatus Substrate and its Potential Use in Dye Removal. [BT32]
By Miss Khor Choo Shan

The application of enzyme in dye removal attracted considerable attention and shown its potential in recent years but the low stability and high production cost of enzyme are the key factors of the application. Tap water was used as solvent to extract the crude enzyme in this study to reduce the production cost. In order to optimise the yield of crude enzyme extract from spent P. ostreatus substrate, parameter such as suspended time duration of spent P. ostreatus substrate in tap water, agitation time and speed in incubator shaker were investigated. The effect of dye concentration, enzyme concentration, pH and temperature in Methylene blue and Rhodamine B removal using crude enzyme extracted were investigated. Bradford test was done to determine the presence of protein in the crude enzyme extracted and Fourier Transform Infrared Spectroscopy (FTIR) was used to determine the presence of functional group in crude enzyme extract. As a result, the optimum parameter to yield crude enzyme is 120 minutes of suspended time, 90 minutes of agitation time at 200 rpm agitation speed. Methylene blue shown the highest dye removal efficiency at 84.23% and Rhodamine B shown low dye removal efficiency <17%. Crude enzyme extracted from spent P. ostreatus substrate is efficient to remove Methylene blue but not efficient to remove Rhodamine B.

In-situ Sterilization of Microalgae Photobioreactor via Ozone-rich Macrobubbles [BT35]
By Miss Aimi Alina Binti Hussin

Aseptic technique plays a critical role in determining high volumes of microalgae biomass during the cultivation stage as the presence of a contaminant is one of the limiting factors. This study focuses on developing an energy-efficient method in sterilizing the 2 L microalgae photobioreactor. Initially, the seawater bacterial contaminant was successfully screened, isolated and identified as Kurthia gibsonii genus (gram-positive) using 16S rRNA gene sequencing. The photobioreactor sterilization using ozonolysis was optimized using one factor at a time (OFAT), with 3 parameters studied: ozone aeration rate, bacterial culture volume and ozonation time. Different bacterial culture volumes (1.0 L, 1.5 L, and 2.0 L) were exposed to ozone gas at 0.5 L/min, 1 L/min and 1.5 L/min for a maximum of 180 minutes with 30-minute intervals. The ozonation technique at optimum condition reduced the contaminants up to 7 log reductions. The initial cells concentration in 1 L culture containing 6.73 × 107 cells/ml was reduced to 7 cells/ml after being ozonated for 180 min. The morphology study of the bacteria before and after ozonation (at 1000X magnification) confirmed that ozonation shattered the cells into small pieces. This study reveals the possibility of replacing energy-intensive sterilization techniques such as the autoclave method with ozonolysis. Ozonation method is more energy efficient, with a total 1.26 kW energy used during the sterilization process as compared to autoclaved method with 3.565 kWh. The study proves that the ozonation method is energy efficient, cheaper and easily applied to a larger industrial scale as well.
