| effect of selected lactic acid bacteria on growth of staphylococcus aureus and production of enterotoxin. | representative strains of 15 species of lactic acid bacteria were examined for their ability to influence growth of staphylococcus aureus and production of enterotoxin in associative culture. among the organisms used as effectors the streptococci were most inhibitory, followed by pediococcus cerevisiae. the lactobacilli and leuconostoc citrovorum were not inhibitory to growth and only slightly inhibitory to production of enterotoxin. enterotoxin was detected in all cultures in which the populati ... | 1973 | 4633430 |
