Acetobacter xylinum 1FO 13693 was selected as the best cellulose-producing bacterium among 41 strains BELONGING to the genus Acetobacter and Agrobacterium. Cellulose was found to be produced at the LIQUID surface in static liquid CULTIVATION. The rate of cellulose production depended proportionally on theAcetobacter xylinum 1FO 13693 was selected as the best cellulose-producing bacterium among 41 strains belonging to the genus Acetobacter and Agrobacterium. Cellulose was found to be produced at the liquid surface in static liquid cultivation. The rate of cellulose production depended proportionally on the surface-area of the culture medium and was unaffected by the depth and VOLUME of the medium. The OPTIMUM pH for cellulose production was 4.0 to 6.0. Glucose, fructose and glycerol were preferred carbon sources for cellulose … surface-area of the culture medium and was unaffected by the depth and volume of the medium.
