The extracellular production of hyaluronidase and chondroitin sulfatase was demonstrated in all of the subspecies of Bacteroides fragilis tested with the exception of B. fragilis subsp. vulgatus. Elastase was found only in one strain of B. coagulans tested. This appears to be the first report of these enzyme activities in this genus. Additional enzymes found to be produced by certain members ot...
Glutamate is the most important excitatory neurotransmitter in the central nervous system which is involved in synaptic transmission, brain development, synaptic plasticity, learning, and memory. Normally, the enzymatic destruction of glutamate does not occur in the synaptic and extracellular space, but glutamate is removed through specific transporter proteins, leading to stabilization of glut...
Trichoderma species have been famous for production of cellulases with relatively high enzymatic activity. However, attempts to use their cellulolytic enzymes in the bioconversion of cellulosic wastes have not been successful because of high cost of production and low enzymatic yields. This study aimed to obtain gamma-induced mutants of T. viride with enhanced extracellular cellulase production...
Cellulase production by a Cellulomonas sp., isolated in 1985 from forest humus soil along the border of the Caspian Sea in Iran, was investigated. This strain secreted endo-and exo-cellulases in the culture medium, but some of the enzymes produced remained cell membrane bound. Cell bound enzymes were released by various treatments. The highest amount of endo-glucanase (up to 95%) and exo-gl...
