Abstract:
The genus Chaetomium features thermotolerant and thermophilic in nature and can grow at various temperatures and pH. This experiment was conducted in 2018-2019 at Navsari Agricultural College N.M. Department of Plant Pathology, Navsari (Gujarat). Total 10 isolates were isolated from various samples. Then from the best isolate (C2), The effect of temperature on isolate was studied and maximum growth was observed at 35 °C. C. brasiliense (C2) grew with a radial growth of 6.48 mm after 7 days of incubation. While no growth was observed at 45 °C. Also, the highest sporulation was recorded in C2 isolate at 35 °C temperature. Maximum growth was observed at pH 8 of C. brasiliense (C2: 6.85 mm) after 7 days of incubation. Sporulation was highest at pH 8 and maximum mycelium weight was found at pH 6.
