DECOMPOSITION OF CHITIN BY MARINE BACTERIA

Application of Chitin-chitosan from Marine By-products in Thailand

Thailand is one of the major producers and exporters of shrimp and other marine products worldwide. Over 600,000 metric tons of marine products containing chitinous materials, shrimp, crab and squid, are produced yearly, which resulted in abundant amount of raw materials for the production of chitin-chitosan. Chitin-chitosan industry in Thailand has grown considerably in the past decade. Howeve...

Chitin Degradation Proteins Produced by the Marine Bacterium Vibrio harveyi Growing on Different Forms of Chitin.

Relatively little is known about the number, diversity, and function of chitinases produced by bacteria, even though chitin is one of the most abundant polymers in nature. Because of the importance of chitin, especially in marine environments, we examined chitin-degrading proteins in the marine bacterium Vibrio harveyi. This bacterium had a higher growth rate and more chitinase activity when gr...

Decomposition of Vitamin C by Bacteria.

The decomposition of vitamin C by bacteria is of double interest to the bacteriologist. Preliminary in vitro studies by Young and James (1942) showed that enteric bacteria of the colon-aerogenes group destroy ascorbic acid with great facility; these findings suggest that, in spite of a diet adequate in this substance, symptoms of vitamin C deficiency in some persons may be traced to an intestin...
