Islation of a PAHs degrading marine bacterium Nah-1 and its degradative gene
一株深海嗜低温萘降解细菌Nah-1的分离及降解基因研究

A PAHs-degrading psychrophilic bacterium,with naphthalene as sole carbon and energy source, was isolated from deep-sea sediment of Southern Okinawa Trough.The growth curve of this bacterium was determined and the optimum growth conditions of this bacterium were studied.16S rDNA sequences analy- sis indicated that it belongs to the genus Cycloclasticus.A fragment of the degrading dioxygenase gene was obtained through PCR from Nab-1.And sequence alignment revealed that it was similar to the phnA1 gene of Cycl...
