Strains: 1, LTYR-11ZT; 2, Pantoea theicola NBRC 110557T; 3, Pantoea intestinalis DSM 28113T. All data were obtained from this study. +, Positive; -, negative; (+), weak. All strains are positive for growth on LB agar, R2A agar, NA and TSA and MacConkey agar, nitrate reduction, hydrolysis of aesculin, carboxymethyl cellulose and 4-nitrophenyl-β-D-galactopyranoside (PNPG), catalase, arginine dihydrolase, leucine arylamidase, valine arylamidase, trypsin, acid phosphatase, naphthol-AS-BI-phosphohydrolase and β-galactosida se, and assimilation of D-glucose, L-arabinose, D-mannose, D-mannitol, N-acetylglucosamine, maltose and potassium gluconate. All strains are negative for hydrolysis of L-tyrosine, starch and chitin, H2S production, oxidase, tryptophan deaminase, esterase (C4), esterase lipase (C8), lipase (C14), cystine arylamidase, α-chymotrypsin, α-galactosidase, β-glucuronidase, α-mannosidase and α-fucosidase and assimilation of capric acid, adipic acid, trisodium citrate and phenylacetic acid.
