Project description:Crystalline chitin is a kind of high molecular-weight polymers which is difficult to degrade. N-acetylglucosamine and chitooligosaccharides (COSs) are important agriculture, medicine, cosmetics and food resources. Conversion of crystalline chitin to GlcNAc and COSs using recombinant chitinases is an environmentally compatible, reproducible and products controllable method. Here, we report the ability of Pseudoalteromonas flavipulchra DSM 14401 to degrade crystalline.
Project description:One of the most distinct features of Pseudoalteromonas sp. SCSIO 11900 is its ability to form a very robust pellicle than most Pseudoalteromonas strains. Thus we want to identify the genes essential for the pellicle formation of SCSIO 11900. We compared transcriptom profiles of planktonic cells, initial pellicle and mature pellicle of coral Pseudoalteromonas sp. SCSIO 11900 and revealed that some unique genes from horizontal gene transfer is involved in the pellicle formation of SCSIO 11900.
Project description:We compared genetic profiles of planktonic stage to biofilm stage of deep sea bacterium Pseudoalteromonas sp. SM9913 and revealed genetic features during switch from planktonic to pellicle stage in Pseudoalteromonas sp. SM9913.
