Crab shell attachment


ABSTRACT: Strain N16961 was incubated with crab shell in artificial seawater media for 24 hours. cDNA from 1 ug RNA was labeled with Cy3 (planktonic bacteria) and Cy5 (crab attached bacteria). A growth condition experiment design type is where some part of the growth condition is changed for the purposes of the experiment, examples of growth conditions changed are media, temperature, humidity, light, nutrients. Using regression correlation

Chitin, an insoluble polymer of GlcNAc, is an abundant source of carbon, nitrogen, and energy for marine microorganisms. Microarray expression profiling and mutational studies of Vibrio cholerae growing on a natural chitin surface, or with the soluble chitin oligosaccharides (GlcNAc)(2-6), GlcNAc, or the glucosamine dimer (GlcN)2 identified three sets of differentially regulated genes. We show that (i) ChiS, a sensor histidine kinase, regulates expression of the (GlcNAc)(2-6) gene set, including  ...[more]
