A two phase anaerobic digestion of banana peel is an attractive process for producing hydrogen and methane. Comparative performance total energy recovery between (sequential methane fermentation) one (methane in were evaluated batch reactor under mesophilic incubation at varying ratios feedstock to microbial inoculum (F/M) ranging from 2.5 – 10. F/M influence biogas yield, production rate, potential. Best fermentation was observed 5.0. At this condition, potential 251.3 mL g-1 VS, 2.05 h-1,...

The current study focused on the feasibility of biogas production from Napier grass. grass, a tropical plant, can grow up in drought and dry conditions. grass contains 30.9% total carbohydrates, 27% protein, lipid 14.8%, ash 18.2%, fiber 9.1% (dry weight). Its organic compositions are an ideal feedstock for production. fresh was harvested after 5 week plantation, grounded 0.5 to 1 mm diameter size before fermentation mesophilic batch reactors, with varying solid concentrations - 15%. optimum...

Total energy recovery from food waste fermentation in a two-stage 5-L CSTR system, which hydrogen and methane production were sequential setup, was evaluated. The first –stage hydrogen, the second-stage produced under mesophilic with initial pH 6 7; hydraulic retention time of 12 24 h, respectively. results showed that yields 292.7 391.6 mL g-1 VS at steady stage operation. yield one-stage 364.3 VS. total process 6.5x10-2 kW-h, while 4.7x10-2 kW-h. research study found consisting potential...

Adsorption of quinoline (pKa = 4.92) and background electrolyte (CaCl2) onto specimen kaolinite montmorillonite were measured as a function pH (3-7.5) ionic strength (1-10 mM), concentration (0.2-1.55 mM) at fixed values maximum adsorption. Maximum sorption occurred 3.5-4.0 for kaolinite, 3.0-5.0 montmorillonite. At their respective adsorption, the capacity was 100 times greater with than on mass basis. Selectivity coefficients, which calculated from edge data, indicated selectivity cationic...

This study focused on the kinetics of biomethane production from raw banana peel. Physical pretreatment by grinding peel into small pieces prior to anaerobic fermentation was used. Experiments were setup in 0.5 L batch reactor under mesophilic condition (37 oC), pH 7 and varied total solids (TS) concentrations 2.5, 5, 7.5 10% w v-1. Air liquid samples collected every 12 hr for gas composition volatile fatty acids (VFA) analyses. At 7.5% TS, maximum yield rate 439 mL g-1 TVS 5.31 hr-1,...

Banana peel and biodiesel derived glycerol are one of the most abundant agricultural waste in Southeast Asian countries. This current research demonstrated potential biomethane production from co-digestion wastes under mesophilic fermentation. The used include (1) banana (varying total solids range 2.5-10% w/v) (2) mixed with pure or glycerol. All treatments were setup duplicate 0.5 L batch reacotr. Gas liquid samples collected every 12 24 hr, respectively. Maximum methane yield 181 mL 188...

Coloured wastewater from the textile industry is a very serious global problem. Among 16 different white-rot fungal isolates, Trametes hirsuta PW17-41 revealed high potential for decolourisation of mixed dyes (Navy EC-R, Ruby S3B and Super Black G) real industrial samples. The efficiency dye was evaluated using American Dye Manufacturers' Institute (ADMI) standard methodology. suitable support mycelium immobilisation nylon sponges. optimal (95.39%) achieved by palm sugar ammonium nitrate as...

Medium chain length polyhydroxyalkanoates (mcl-PHAs) are biopolyesters, derived from renewable biomass resources such as palm oil. These PHAs can be converted to added value products biopolymers, potentially increasing the economical worth of crude Batch experiments were set up in an orbital shaker incubator at 30 ​°C explore feasibility biosynthesized by Pseudomonas aeruginosa TISTR 1287 P was cultured under varied oil concentrations (0.50–2.00% w v−1) and initial pH 7. The cultivation time...

Palm oil mill effluent (POME) contains high organic compounds and nutrients suitable for microorganisms in anaerobic processes. The biological hydrogen production using raw POME ozonated thermophilic batch fermentation at varying concentration the range of 5,000 to 35,000 mg COD L-1 was examined. Hydrogen achieved maximum yield 77.1 mL g-1COD L-1, which higher than that from by 20%. Meanwhile rate 10.8 h-1 observed 25,000 L-1. Greater removal 25% compared POME. main acetic butyric acids were...

Biological fermentative production of hydrogen from the ozonated palm oil mill effluent (POME) was conducted in batch reactors using an anaerobic sludge as a microbial seed. Fermentation setup at pH 4.0-6.0, varying POME concentration range 5,000-37,000 mg L-1 under mesophilic condition (37 °C). The results showed that 6.0 is optimum and maximum yield 28.3 mL g-1 COD obtained. Comparative raw versus indicated ozone pretreatment (mg COD: = 102.8) elevated biodegradability constituents...
