Abstract: A correlation between the physiological and biochemical characteristics of cellulase producing bacteria isolated from wine fermented grains and cellulose enzyme activity was studied using correlation analysis and path analysis. Results of correlation analysis and path analysis showed that cell aspect ratio and acid production indicator using glucose had clear negative correlations with cellulase activity, while starch hydrolysis test indicator had positive correlation with cellulase activity. Cell aspect ratio had the largest negative direct effect on cellulase activity. Acid production indicator using glucose had strong negative direct effect on cellulase activity. Gas production indicator used glucose and casein test indicator had strong positive direct effects on cellulase activity, as well as individual indicators also had indirect effects on cellulase activity through other indicators.
