Anaerobic saccharolytic bacterial adhesion to raw starch granules

Abstract

The experiment of bacteria adhesion onto starch granules is conducted. It is found that anaerobic saccharolytic bacteria have the highest adhesion ability in their growth and initial stage of stationary phase. Starch granules with a low crystallinity, low bulk density, and high water‐holding capacity have a high adhesion capacity. The optimum temperature for both bacterial growth and their adhesion is 30°C. The optimum pH for the bacterial adhesion range from 5.0 to 6.5. Anaerobic conditions cause an appreciable decrease in percentage of adhesion. The percentage of adhesion is not sensitive to the type of soluble saccharide on which bacteria were grown.
