Abstract:
A bacterium D 97 whose enducellular enzymes can produce trehalose from starch or maltooligosaccharides was isolated from Datian in Northeast of China The morphological, Cultural and Physiological Characteristics of trehalose prodicing bacterium D 97 were described in this paper There are galactose and lysine in its cell wall but no diaminopimelic acid (DAP) arabinose The content of G+C mol% is 61 3 The full lenth of 16s rDNA (770bp) has been tested and compared with the type strains of all known Arthrobacter sp in Genebank, the results showed the similarity values of 16s rDNA sequence between bacterium D 97 and Arthrobacter nicotinovorus were 97 98%, therefore bacterium D 97 was nameed Arthrobacter nicotinovorus D 97 In this paper we also carried out some comparisons of Physiological Characteristics between Arthrobacter nicotinovorus D 97 and Arthrobacter sp Q36
