BACKGROUND Laccases have potential applications in detoxification of lignocellulosic biomass after thermochemical pretreatment and production of value-added products or biofuels from renewable biomass. However, their application in large-scale industrial and environmental processes has been severely thwarted by the high cost of commercial laccases. Therefore, it is necessary to identify new lac...

The brown seaweed Sargassum sp. is a promising feedstock for ethanol production because of its relatively high content (41.6% dry basis) of holocellulose. Chemical pretreatment of the seaweed was carried out with 1% (v/v) H SO solution at 5% solid loading for 15 min at 121°C prior to saccharification with 2 4

conclusions the produced compost in this study was mature and ready for use as an agricultural substrate or soil conditioner after 80 days of composting. results the results showed that the c/n ratio decreased during the composting process (reached to 15.6) due to the loss of carbon and the increase in nitrogen content per unit material; also, the nh4+/no3 ratio decreased with increase in the t...

Twenty-five subjects evaluated the sweetness, creaminess and fat content of liquid and solid dairy products containing between 0.1 and 52 g fat/100 g and sweetened with 0-20% sucrose weight/weight. Liquid stimuli included skim milk, whole milk, half and half, and heavy cream, while the solids included cottage cheese and cream cheese, blended and spread "jelly-roll" fashion on slices of white br...

This experimental study investigates the strength characteristics of cemented super-fine unclassified tailings backfill (CSUTB) and its failure mechanism. Physical and chemical properties of tailings from the Zhongguan Iron Mine (ZGIM) were tested. A series of uniaxial compressive strength (UCS) tests was conducted to determine the relationships between UCS of CSUTB and three factors of cement-...

This study was to evaluate the feasibility of recycling the solids separated from swine wastewater treatment process as a fuel source for heat production and to provide a data set on the gas emissions and combustion properties. Also, in this study, the heavy metals in ash content were analyzed for its possible use as a fertilizer. Proximate analysis of the solid recovered from the swine wastewa...

A method for long chain fatty acids (LCFA) extraction, identification and further quantification by gas chromatography was developed and its application to liquid and solid samples collected from anaerobic digesters was demonstrated. After validation, the usefulness of this method was demonstrated in a cow manure digester receiving pulses of an industrial effluent containing high lipid content....

Solid state fermentation of brewery spent grain (BSG) was carried out in this study using Aspergillus oryzae. Fungi isolates obtained from the samples of brewery spent grain collected from Nigerian Brewery Plc., Ibadan, Oyo State, Nigeria, were isolated and identified. Isolate with high percentage of occurrence was tested for the ability to grow and improve protein content of spent grain. The i...
