production of lignocellulolytic enzymes by the thermotolerant fomes sp. eum1 was determined in solid cultures using corn stover (cs) as a sole substrate or supplemented with 20 % wheat bran (cs+wb). this supplementation increased (p< 0.05) enzymatic activity per gram of initial dry matter (gdm) for xylanases and cellulases: 160 iu g dm-1 and 37 iu g dm-1, respectively; while laccases reached a ...

the effect of feeding barley-based diets (%60) supplemented with four commercial enzymes containing xylanase and ?-glucanase activities were investigated on performance and gastrointestinal size of broiler chicks. the enzyme supplemented diets were compared with unsupplemented barley- or corn-based diets. a total of 234-day-old male broiler chicks (ross 308) were allocated to 6 treatment groups...

Biocatalysis is a useful tool in the provision of chiral technology and extremophilic enzymes are just one component in that toolbox. Their role is not always attributable to their extremophilic properties; as with any biocatalyst certain other criteria should be satisfied. Those requirements for a useful biocatalyst will be discussed including issues of selectivity, volume efficiency, security...

in this research the effect of feeding wheat/ barley based diets supplemented with three commercial enzymes containing xylanase and ?-glucanase activities and including matrix value their on performance and gastrointestinal tract size of broiler chicks was investigated. a total of 260-day-old male broiler chicks (ross 308) were allocated to 5 treatment groups, with 4 replicates per treatment an...

Agaricus bisporus, grown under standard composting conditions, was evaluated for its ability to produce lignin-degrading peroxidases, which have been shown to have an integral role in lignin degradation by wood-rotting fungi. The activity of manganese peroxidase was monitored throughout the production cycle of the fungus, from the time of colonization of the compost through the development of f...
