Utilization of orange peels as an agroindustrial waste for production of pectin lyase (PL) [E.C.4.2.2.10] by Curvularia inaequalis (Shear) Boedijn NRRL 13884 was investigated using solid state culture (SSC). The highest level of extracellular pectin lyase was detected with this waste as an inducing substrate. The enzyme was purified using Sephadex G-100 and DEAE-Cellulose column chromatography....

Twenty thermophilic/thermotolerant fungal strains were isolated from compositing soils and screened for production of different enzymes (Endoglucanases, β-glucosidase, Fpase and xylanases) to assess their deinking efficiency. Three isolates, Aspergillus sp. AMA, Aspergillus terreus AN1, and Myceliophthora fergusii T4I, identified on the basis of morphological and sequencing of amplified ITS1-5....

We have developed a new method to efficiently convert waste biomass (agricultural, municipal, forestry) into biofuels and value-added products. The process is completely chemical in nature, inexpensive, and produces no waste stream. The derived products are non-toxic, biodegradable substitutes for petroleum, both in motor fuels and as renewable chemical intermediates. The technology involves th...

The screening and isolation of fungi producing a cocktail of hydrolytic enzymes was studied. Among the various isolates obtained from different soil samples, a strain NS-2 was selected. The phylogenetic analysis of this strain showed highest homology (99%) with Aspergillus niger. It was capable of producing cellulolytic, hemicellulolytic, amylolytic, and pectinolytic enzymes in appreciable tite...

The transformation of organic matter during anaerobic digestion of mixtures of energetic crops, cow slurry, agro-industrial waste and organic fraction of municipal solid waste (OFMSW) was studied by analysing different samples at diverse points during the anaerobic digestion process in a full-scale plant. Both chemical (fiber analysis) and spectroscopic approaches ((13)C CPMAS NMR) indicated th...

Abstract Plastic is a product widely used daily and contributes to huge waste, which can cause potential environmental impact worldwide. The production of bioplastics lessen plastic waste while also benefiting the environment. There are still few studies examining influence in different contexts. This investigation assesses cradle-to-gate life cycle durian peel-derived considering their contrib...

Because there is a lack of wood resources in many countries, this work focused on pulp and paper production from the waste agricultural residues non-wood plants. The aimed to nitrate-alkaline black mustard (Brassica Nigra L.) camelina (Camelina Sativa L.). were selected due expanding planted areas these crops Czech Republic. To characterize chemical composition camelina, cellulose, lignin, ash,...

Rock phosphate (RP) addition in cow-dung waste-paper mixtures at rates above 2% P has been reported to increase the rate of bio-transformation and humification of organic waste mixtures during vermicomposting to produce organic fertilizer for organic farming. However, the optimization of RP for vermicomposting was not established. The objective of this study was to determine the optimal amount ...

The utilization of agrowaste for the production of bioethanol has attracted worldwide attention as a strategy for reducing global warming and improving global energy security. Sorrel drink, popularly known as “zoborodo” in Nigeria is a non-alcoholic drink, which is obtained from the calyces of Hibiscus sabdariffa, by solid-liquid extraction process, leaving the calyces pulp as the raffinate. Th...

Municipal solid waste contains high amounts of cellulose, which is an ideal organic waste for the growth of most of microorganism as well as composting by potential microbes. In the present study, Congo red test was performed for screening of microorganism, and, after selecting a potential strains, it was further used for biodegradation of organic municipal solid waste. Forty nine out of the 25...
