The importance of Geobacillus spp. as group of bacterial contaminates in the dairy industry [electronic resource].

Includes references.

Infant formulae are modern artificial substitutes for human breast milk. Formulas are designed for infant consumption, and are usually based on either cow milk or soy milk. Geobacillus represents aerobic or facultative anaerobic, neutrophilic, obligatory thermophilic, endosporeforming bacteria. A total of ninety random samples of milk powder, Infant milk powder and milk-cereal based weaning food (30 samples each) were purchased from different shops and pharmacies in Assiut city. Samples were examined for total thermophillic count, total spore count at 37°C and 55 °C. The incidences of Geobacillus spp. and other bacillus spp. were also determined. The mean value of total thermophillic colony count/g was 10x10³; 13x10³ and 12x10³/ g of examined dried milk powder, infant milk formulae and milk-cereal based weaning food samples, respectively at 37°C. While at 55°C, it was 1x10² and 7.6x10²/g in the same samples, respectively.
