The ability of a Bacillus subtilis strain to grow and produce biosurfactant on different carbon and nitrogen sources under thermophilic conditions (45°C) was studied. The strain was able to reduce surface tension to 34 dynes cm−1 on 2% sucrose, and 32 dynes cm−1 on starch after 96 h of growth. The biosurfactant was stable at 100°C and within a wide pH range (3.0–11.0). Biosurfactant formation at mesophilic conditions (30°C) was also studied. The organism was able to produce the maximum amount… CONTINUE READING
