Lactic acid bacteria (starter microflora) resulted in high numbers (> 107 colony-forming units (cfu)/g). Coliform and yeast counts were lower than 104 cfu/g. Cremoso cheeses were blown by leuconostocs, lactobacilli and Bacillus polymyxa. Mozzarella was spoiled by B. polymyxa and Bacillus macerans. Semihard cheeses were affected by spore-forming (Clostridium and Bacillus), propionic and lactobacilli strains. Clostridia, Bacillus, leuconostocs and heterofermentative lactobacilli were detected in pasteurized milk. Bacillus strains were not previously associated with blowing in soft and semihard cheeses.
