Two isolates of wood-decay basidiomycetous fungi from the Sonoran Desert were selected from a preliminary screening of an extensive collection of wood-decay fungi. The isolates produced extracellular, alkaline-active carboxymethyl cellulase (CMCase) and filter paper cellulase activity, especially on solid substrates. Cultivation on wheat bran gave a higher cellulase yield than cultivation on co...

Cutaneotrichosporon oleaginosus is an oleaginous yeast with several favourable qualities: It fast growing, accumulates high amounts of lipids and has a very broad substrate spectrum. Its resistance to hydrolysis by-products makes it promising biocatalyst for custom tailored microbial oils. C. can accumulate up 60 wt.% its biomass as lipids. This species able grow by using compounds substrate, s...

Waste pickers in Jambi city reduce solid waste by collecting and sorting recycled at the ‘Solid Temporary Shelters’ or Tempat Pembuangan Sementara (TPS). However, most cannot improve their performance due to challenges confronting lack of attention from government public. This research identified quantified collected marketed individual collectors ‘pengepul’. Convenience sampling methods with l...

This study used the subcritical hydrothermal liquefaction technique (SHLT) in co- of process rejects at a wastepaper-based paper mill (PRWPM) and waste soybean oil (WSO) for production biofuels bio-char material. PRWPM emits complicated composed cellulose, hemicellulose, lignin, plastic from sealing film. The is produced recycled plant located central Taiwan. source WSO rejected organic cooking...

Among low cost and widely available raw materials, wastepaper sludge ash is of key interest as potential construction material. These materials come from the paper recycling industry. In present study, (WSA) retrieved UPM Chapelle Darblay Company located in south Rouen, France, were subjected to preliminary physicochemical characterization by X-ray fluorescence, laser granulometry scanning elec...

Filled thermoplastic composites are stiffer, stronger, and more dimensionally stable than their unfilled counterparts. Such thermoplastics are usually provided to the end-user as a precompounded, pelletized feedstock. Typical reinforcing fillers are inorganic materials like talc or fiberglass, but materials derived from waste wood, such as wood flour and recycled paper fiber, are also effective...

Abstract In this study, an eco-friendly controlled release fertilizer cellulose-based hydrogel was prepared from cellulose fibers derived wastepaper, epichlorohydrin (ECH) as a crosslinker and carboxy methyl (CMC) gelling agent. A maximum swelling capacity of 2000% achieved for with optimum composition. The soil moisture contents in the presence optimized hydrogels were determined using digital...

Two enzymatic extracts obtained from xylan-grown Aspergillus terreus CCMI 498 and cellulose-grown Trichoderma viride CCMI 84 were characterised for different glycanase activities. Both strains produce extracellular endoxylanase and endoglucanase enzymes. The enzymes optimal activity was found in the temperature range of 45-60 degrees C. Endoglucanase systems show identical activity profiles tow...
