Morphological and physiological identification showed that NTG-01 was Gram-negative, short rod shape, with flagella around the bacteria, V-P test positive and Methyl red test negative. The bacterium can use glucose as carbon suource and produce gases. No H2S produced on TTS medium. Lysine decarboxylase and orthinine decarboxylase, catalase and gelatine test are positive. Arginine decarboxylase, dehydrolase, oxidase and urase test are negative. Sequencing and alignment of 16S rDNA showed that it shared a 99% homologous sequence with Enterobacter aerogenes.
