The morphological analysis of strain EMZY-1 showed that it was a straight rod, about 0.3×1.7 in size, and spherical and terminal spore appeared. Results of physiological and biochemical test showed that strain EMZY-1 was a Gram-positive bacteria, and could not grow when temperature was lower than 10℃ or higher than 60℃, pH was lower than 5.0 or higher than 12.0, and the concentration of NaCl was more than 10%. The strain EMZY could grow on the medium as a of sugar, glucose and mannite. The strain could use saccharose, glucose and mannitol as carbon resource, and NH4(superscript +) and NO3(superscript -) as nitrogen resource.
