Abstract

Abstract

Foams and blocks were produced in the circulating water system of a coal-to-methanol plant due to slight leakage. The fouling was identified to be mainly bacterial cellulose after optical microscopic observation, scanning electron microscopy and chemical coloration analysis, from where a dominant strain was obstained by microbiological isolation. The strain was identified as a strain of Gluconacetobacter xylinus, according to 16S rDNA sequence and BIOLOG identification. Cellulose production of the strain were studied under different conditions. The results showed that pH and methanol concentration had a great influence on the cellulose production of the strain. Maximum cellulose production appeared when methanol concentration 15~25 mL/L, and the cellulose production with pH of 8 and 9 was only 50% of that with pH of 5.0. When co-growth with methanol-degrading bacteria, cellulose-producing ability of the strain decreased by 37.9%, owning to competitive exclusion and niche competition. This discovery provided a scientific basis for the biological control of cellulose fouling in the coal-to-methanol circulating water system.
