Cellulases and xylanase of an anaerobic rumen fungus grown on wheat straw, wheat straw holocellulose, cellulose, and xylan.
The activities of cellulolytic and xylanolytic enzymes produced by an anaerobic fungus (R1) which resembled Neocallimastix sp. were investigated. Carboxymethylcellulase (CMCase), cellobiase, and filter paper (FPase) activities had pH optima of 6.0, 5.5, and 6.0, respectively. CMCase and cellobiase activities both had a temperature optimum of 50 degrees C, whereas FPase had an optimum of 45 degr...
متن کاملDevelopment and implementation of rapid metabolic engineering tools for chemical and fuel production in Geobacillus thermoglucosidasius NCIMB 11955
BACKGROUND The thermophile Geobacillus thermoglucosidasius has considerable attraction as a chassis for the production of chemicals and fuels. It utilises a wide range of sugars and oligosaccharides typical of those derived from lignocellulose and grows at elevated temperatures. The latter improves the rate of feed conversion, reduces fermentation cooling costs and minimises the risks of contam...
متن کاملIsobutanol production at elevated temperatures in thermophilic Geobacillus thermoglucosidasius.
The potential advantages of biological production of chemicals or fuels from biomass at high temperatures include reduced enzyme loading for cellulose degradation, decreased chance of contamination, and lower product separation cost. In general, high temperature production of compounds that are not native to the thermophilic hosts is limited by enzyme stability and the lack of suitable expressi...
متن کاملBiodegradable Nanocomposites from Wheat Straw
We investigate the mechanical and thermal properties of cellulose nanofiber reinforced starch based thermoplastic composites. Cellulose nanofibers were isolated from wheat straw by a chemi-mechanical technique. Their morphology, physicochemical and thermal properties were investigated to examine potential applications as reinforcement fibers in biocomposites. Transmission electron microscopy re...
متن کاملCombustion of pellets from wheat straw
The alternative energy sources are more and more used for production of heat. Several new combustion devices allow co-firing of different fuels, like dendromass and phytomass. The article analyses combustion of wood and straw pellets in the same boiler. Measurements were realized in two automatic heat sources – one is adapted to burn pellets made from wood or straw and another allows only burni...
