In this study, the primary paper-mill sludge characterized as containing 51% glucan was used to optimize enzymatic saccharification process for production of bioethanol using a Box–Behnken design (BBD). Polyethylene glycol 4000 (PEG-4000) surfactant-assisted dried (DPS) showed 12.8% improvement in efficiency. There statistically significant effect solid enzyme loading and time on DPS at 95% con...

The parameters of the alkaline fractionation process were investigated and optimized using a statistical analysis method to simultaneously remove hemicellulose ash from rice husk (RH) concomitantly. After process, residual solid contained high cellulose, recovery yield was enhanced in fractionated liquid hydrolyzate. hemicellulosic sugar (71.6%), de-ashing (>99%), lignin removal (>80%) ob...

objective(s): to understand the role of mitochondrial respiration in cisplatin sensitivity, we have employed wild-type and mitochondrial dna depleted rho0 yeast cells. materials and methods: wild type and rho0 yeast cultured in fermentable and non-fermentable sugar containing media, were studied for their sensitivity against cisplatin by monitoring growth curves, oxygen consumption, ph changes ...

Algal biorefinery process utilizes every component of algal biomass to produce multiple useful fuel products. In this technique, acid pretreatment of algal biomass hydrolyzes microalgal carbohydrates into fermentable sugars, makes lipids more extractable and a protein part accessible for additional products. In the present study, Chlorella sorkiniana produced higher quantity of biodiesel than B...

Balancing the needs of current and future generations stimulates investment for sustainable development such as converting waste biomass into biorenewables. Sugar-based ethanol production is a well-investigated established process, researchers are now focusing on transformation cellulosic to sugar application non-conventional methods production. The State Qatar generates date palm fruit approxi...

The use of plant waste product for maximum sustainability has led to the search bio based raw material such as Chlorella vulgaris which can make a tremendous contribution on ecological and economical production different organic acids like lactic acid. This study aimed evaluate enzymatic or acidic hydrolysis cell wall Intercellular starch source fermentable sugar acid production. Lactic was pro...

The current work is a basic study on utilization of fruit peels banana, muskmelon, pineapple and water melonas lignocellulosic sources for the production bioethanol. Fruit contain good amounts cellulose hemicellulose which can be pretreated to release fermentable sugars. Efforts were directed towards understanding critical factors influencing substrate loading, acid hydrolysis fermentation para...

a solid state fermentation method was used to utilize wheat straw as substrates for citric acid production by using aspergillus niger atcc 9142. the plackett burman design (pbd) of experiments was used to test the relative importance of the variables affecting production such as moisture content, age of spore, inoculum size, initial ph of substrate, methanol concentration, incubation temperatur...
