Optimization of culture conditions for cellulase production by microbial consortium VI by the single factor approach. In Panel (A), the temperature was 30°C, the pH was 7, and the inoculum volume was 5% (v/v); in Panel (B), the culture time was 4 days, the pH was 7, and the inoculum volume was 5% (v/v); in Panel (C), the temperature was 35°C, the culture time was 4 days, and the inoculum volume was 5% (v/v); in Panel (D), the temperature was 35°C, the culture time was 4 days, and the pH was 6.5. (A) Effect of time on enzyme production by consortium. (B) Effect of temperature on enzyme production by consortium. (C) Effect of initial pH on enzyme production by consortium. (D) Effect of inoculation volume on enzyme production by consortium. Error bars represent standard deviation; they were calculated using data from 3 technical replicates. Different letters (e.g., “a,” “b,” “c,” and “d”) represented significant difference (p < 0.05).
