Chitinase from streptomyces griseus for Sale

Chitinase from streptomyces griseus occurs as a light brown powder. Trichoderma reesei but a rice family 19 chitinase did not. In order to investigate the effects of ChiC as an increaser of plant resistance to fungal diseases, the chiC gene was introduced into rice plants under the control of the increased CaMV 35S promoter and a signal sequence from the rice chitinase gene. Transgenic plants were morphologically normal. Resistance to leaf blast disease caused by Magnaporthe grisea was evaluated in R1 and R2 generations using a spray method.
Ninety percent of transgenic rice plants expressing ChiC had higher resistance than non- transgenic plants. Disease resistance of sibling plants within the same line was correlated with the ChiC expression levels. ChiC produced in rice plants accumulated ntercellularly and had the hydrolyzing activity against glycol chitin. Streptomyces griseus has been used as a plentiful source for antibiotics for a long time but is now beginning to come upon a new field, the purifying of water.
One unit will liberate 1.0 mg of N-acetyl-D-glucosamine from chitin per hour at pH 6.0 at 25 °C in a 2 hour assay. One new 1 hour unit = approx. 50 old 48 hour units. Streptomyces griseus is a member bacterial species of the genus Streptomyces and are commonly found in soil. A few strains have been also reported from deep sea sediments. These are Gram positive bacterium with high GC content. Along with most other streptomycetes S. griseus strains are well known producer of antibiotics and other such commercially significant secondary metabolites. This product is ight brown powder.Used in organic synthesis.
