    Studies on Heat Resistant Bacillus Strains Isolated From Different Fermented Foods With Special Reference to Emetic Enterotoxin
    (Birsa Agricultural University, Ranchi, 1998) Ram Sarikh Prasad; Dr. Md Kalimuddin
    1.Twenty five samples (20.83%) were found positive for heat resistant Bacillus cereus out of hundred twenty samples of different fermented foods. 2. All the five types of fermented foods viz. dosa premix, rice beer, idli, curd and soysauce examined, were found to be contaminated with heat resistant Bacillus cereus. The incidence of Bacillus cereus in dosa premix, rice beer, idli, curd and soysauce was 37.50%, 33.33%, 25.00 % , 4.16% and 4.16%, respectively. 3. Area-wise incidence of heat resistant Bacillus cereus in fermented foods viz. Dhurwa, Hinoo, Main road Ranchi, Kanke and Kanke road was 23.21%. 16.65%, 19.98% 23.21%, respectively. 4. The bio typing of the isolates revealed that the fermented foods were contaminated with biotypes 1(16.00 %), 2 (4.00%), 4 (72.00%), 5 (4.00%) and 8 (4.00%). This would help to understand the epidemiology of food poisoning due to Bacillus cereus. 5.Most of the isolates from fermented foods ferment xylose (84.00%) and the findings are in accordance with the European. reports.
