Chitosan is prepared by the deacetylation of chitin, the second-most abundant biopolymer in nature, and has applicability in the removal of dyes, heavy metals and radioactive waste for pollution control. In weight-reduction remedies, chitosan is used to form hydrogels with lipids and to depress the intestinal absorption of lipids. In this study, an experimental method was implemented to simulat...

The purpose of this study was to utilize low quality date syrup, a rich and available source of nutrient in Iran, for the production of bacterial cellulose using Gluconacetobacter xylinus. Static batch fermentationfor the purpose of cellulose production by G. xylinus (PTCC, 1734) was studied using low quality date syrupand sucrose solution (Bx. 10%) as fermentation media at 28°C. Re...

Methane was generated from cotton waste, while considering its pollution in textile industries. Cotton waste includes solid content and is rich in cellulose having a moisture content of 8.8%. It is difficult to form slurry as the waste float on water and hence an experimental set up has been made like a batch type digester and experiments were conducted with a different proposition of water wit...

The cellulase producing bacteria was isolated from cow dung and characterized by morphological and biochemical analysis. Further partial purification of cellulase was carried out by dialysis and ammonium phosphate precipitation and also to determine molecular weight by SDS-PAGE. Bacterial isolated were grown on Carboxy Methyl Cellulose (CMC) agar at various optimum conditions such as parameters...

Lignocelluloses are the most abundant organic compound in the nature. The cellulosic waste can be used as a potential source of Bio-energy. For the conversion of cellulosic waste to a fuel source, the complex structure of cellulose has to be broken and the glucose monomers obtained can be fermented to bio-ethanol the methods present today are chemicals and enzymatic method. Chemicals methods ar...

Trichoderma viride QM9123 fermented fiber isolated from feedlot waste at concentrations up to 16.7% solids. The fermented fiber solids decreased by 32%, and carbohydrate decreased by 60%. Cellulotyic enzyme production was better with fiber substrates that had been alkali pretreated and had a lower hemicellulose-to-cellulose ratio.

Paenibacillus glucanolyticus 5162, a bacterium isolated from soil, and Paenibacillus glucanolyticus SLM1, a bacterium isolated from pulp mill waste, can utilize cellulose, hemicellulose and lignin as sole carbon sources for growth. These two strains of Paenibacillus glucanolyticus were sequenced using PacBio and Illumina MiSeq technologies.

from the sago palm is the starchy fibrous pith residue. This residue is abundantly and cheaply available especially in the state of Sarawak, Malaysia. It is usually washed off into drains or nearby streams together with wastewater, thus contributing to pollution load, or deposited in the factory’s compound, which can lead to serious environmental problems. It has no significant industrial or co...

Waste with high biomass content generated in cities in developing countries is sent to landfills or open dumps. This research aims to degrade biomass content in urban waste through cultivation, at pilot scale, of the edible mushroom Pleurotus ostreatus. First, the number of diapers used by one baby per week was measured with a survey in day care facilities. Then, cellulose content of diapers wa...
