RESUMO

Acetic acid bacteria of the Acetobacter genus have been identified at the sugarcane mill, in ethanol plants. Out of a total of 32 strains, classified as Acetobactersp., 11 (34,37 %) have been isolated in the Cush-Cush sieve, 3 (9,38 %) have been isolated from the collect tank walls of the newly filtered sugar juice in the Cush-Cush, 15 (46,87 %) have been isolated from newly filtered sugar cane and 3 (9,38 %) have been isolated from the Separator. The strains identified as acetic acid bacteria have been tested as for their fermenting capacity in a discontinued processo The specific rate of acid production and productivity have been analysed based on the cell growth chart and acid production. The CCT 2910, CCT 2023 and CCT 2924 Acetobacter sp. strains have showed high acid production rates after 48 hours of fermenting and the best specific rates of acid production and productivity among of the strains studied in this paper.
