Abstract:
A strain of Cellulosimicrobium cellulans Ha8 was studied on its morphological, biological characteristics and its utilization of several kinds of benzoic compounds, the results showed this strain was Gram-positive, the long rod-shaped cells were changed into short rod-shape gradually. pH value from pH 6.0 to pH 9.0 and the temperature from 20 ℃ to 40 ℃ were good for its growth. It could not only hydrolyze protein and starch, use cellulose and pectin, decomposite chitin, liquify gelatin and fix nitrogen, but also use phenol, xylene, benzoic, cinnamic acids and diphenlamine as the sole carbon resource for its growth. It could tolerate 0 mmol/L~30 mmol/L, 0 mmol/L~8 mmol/L, 0 mmol/L~30 mmol/L, 0 mmol/L~15 mmol/L and 0 mmol/L ~ 40 mmol/L of benzoic acids, phenol, xylene, cinnamic acids and diphenlamine seperately, but could not use 2,4-dinitrophenol, o-Nitrophenol, 2-Methoxyphenol, aminobenzenesulfonic acid, catechol and o-Phenanthroline as its sole carbon resource.
