Agriculture waste such as sugarcane bagasse (SCB) is composed mostly of cellulose, a very versatile natural biopolymer with well-established applications in many industries. The purpose this study was to use combination treatment methods which include alkaline and mild acid hydrolysis assisted ultrasonication extract cellulose nanofibers (CNFs) from bagasse. Initially, the SCB fibers were treated sodium hydroxide aqueous hydrogen peroxide, bleaching agent, before being subjected hydrolysis,...

Halotolerant proteases are known as one of the important groups enzymes that have been used widely in various industries.However, high production cost term energy for sterilization and risk microbial contamination during fermentation become obstacles upstream processing.Moreover, capable to withstand with harsh conditions salinity, temperature pH required industry.Therefore, this study presents newly isolated halophilic bacteria producing halotolerant proteases.Halophilic were from fermented...

Abstract The oil palm industry is known as the primary producer of biomass in Malaysia. massive production has resulted a significant waste disposal problem. This study aims to assess potential derived from plantations and processing mills be transformed into value-added products for various applications. was conducted on three estates managed by Boustead Rimba Nilai Berhad using data generation rates fresh fruit bunches (FFB), crude (CPO), 2018 2020. availability FFB, CPO, empty (EFB)...

Abstract In this study, the potential of an improved empty fruit bunch-based powdered activated carbon (PAC) with high surface area was employed in removing suspended solids and turbidity from a high-strength wastewater. Also, effects operating parameters, such as PAC dosage, contact time mixing speed on sorption trends two pollutants wastewater—biotreated palm oil mill effluent using full factorial experimental design investigated. Adsorption efficiency 89.1 91.4% were observed for...

Astaxanthin is one of the main carotenoid pigments. It has beneficial effects on immune system human body due to its powerful antioxidant properties. The application this bioactive compound can be found significant in food, pharmaceutical, and cosmetics industries. aim research was investigate astaxanthin yield from six species Malaysian shrimp carapace. Six types species-Parapenaeopsis sculptili, Metapenaeus lysianassa, Macrobrachium rosenbergii, Metapenaeopsis hardwickii, Penaeus...

Textile and dye industries pose a serious threat to the environment. Conventional methods used for treatment are generally not always effective environmentally friendly. This drove attention of scores researchers investigate alternative biodegradation dyes using fungal strains. In this work, white-rot fungus (Panus tigrinus) was as biosorbent decolorization Reactive Blue 19. The process parameters that were varied initial concentration (50–150 mg/L), contact time (30–90 min), pH (2–6)....

Global concern on petroleum based plastics which is non-degradable in our environment has led researchers to develop biodegradable plastics. However, have poor barrier properties because of their hydrophilic character biopolymers. It known that incorporation nanocellulose extracted from plant sources improve biocomposites its nanoscopic structure. This study aims film PVA/Starch and sugarcane bagasse. Investigation the effect bagasse nanofibre (SCB-NF) content, PVA starch content water...

A newly bacterial producing L-asparaginase was successful isolated from Sungai Klah Hot Spring, Perak, Malaysia and identified as Bacillus sp. It the best producer compared to other isolates. Production of microbial strain carried out under liquid fermentation. The crude enzyme then centrifuged precipitated with ammonium sulfate before further purified chromatographic method. ion exchange chromatography HiTrap DEAE-Sepharose Fast Flow column followed by separation on Superose 12 gel...

Abstract Penaeus monodon is a species of shrimp with astaxanthin content that prevents various diseases and enhances immune system. High‐pressure processing (HPP) capable achieving higher extraction yield within short time. The aim this research was to optimize the condition from P. using HPP response surface methodology (RSM). investigation carried out variables: pressure (150–250 MPa), holding time (10–20 min), amount acetone‐methanol mixture, 7:3, vol/vol (3–7 ml). optimum achieved at...

Production of lactic acid and ethanol from inedible cassava starch leaves was investigated. Prior to fermentation, hydrolysis the conducted. Hydrolysis optimized by manipulating at three levels each four particular factors, namely concentration, temperature, reaction time. Maximum glucose yield 0.96 g/g obtained when 2.5% (w/v) with hydrolyzed using 0.20 M nitric 160oC temperature for 10 min. The potential then investigated production fungal Rhizopus sp. fermentation process conducted in...

Solid coconut waste (SCW) is a by-product of milk production which still contains virgin oil (VCO). This usually thrown away or left in fields. study aims to optimize the effects Microwave power (80–400 W), irradiation time (1–4 minutes), and solvent feed ratio (SF) (10–30 ml/g) on extraction VCO from SCW using microwave-assisted extraction. The optimized conditions were microwave power: 160 W, Irradiation time: 2.5 minutes, SF: 30 ml/g (15.93% yield). After extraction, characteristics such...
