A total of 84 of 150 vancomycin-resistant (defined as no inhibition of bacterial growth around a 30-micrograms vancomycin disk placed on 5% sheep blood-Trypticase soy agar [BBL Microbiology Systems, Cockeysville, Md.]) bacteria were definitively identified by determining the phenotypic criteria. The identity of representatives was also confirmed by DNA-DNA hybridizations. The following strains ...

Pediococci are homofermentative, gram-positive, nonmotile, catalase-negative facultative anaerobes of the family Streptococcaceae and are used in the biotechnology and food industries (1, 2, 7). The ecologic niche of pediococci in humans appears to be the enteral tract (7). Although pediococci have been described as harmless bacteria (5), they have been infrequently recovered from the human res...

Ninety-two strains of lactic acid bacteria (LAB) were isolated from a Malaysian food ingredient, chili bo, stored for up to 25 days at 28 degreesC with no benzoic acid (product A) or with 7,000 mg of benzoic acid kg-1 (product B). The strains were divided into eight groups by traditional phenotypic tests. A total of 43 strains were selected for comparison of their sodium dodecyl sulfate-polyacr...

In the present work, five hundred and sixty-seven isolates of lactic acid bacteria were recovered from raw bee pollen grains. All isolates were screened for their antagonistic activity against both Gram-positive and Gram-negative pathogenic bacteria. Neutralized supernatants of 54 lactic acid bacteria (LAB) cultures from 216 active isolates inhibited the growth of indicator bacteria. They were ...

One of the lactic acid bacteria that has potential to produce crude bacteriocin is Pediococcus acidilactici BK01, which result isolated from Bekasam. Crude Bacteriocin BK01 a high-temperature resistance 121°C, indicated by antibacterial activity E. coli O15: H7 and S.aureus ATCC25923 extensive pH stability against Escherechia sensitive proteolytic enzymes. still shows during 30 days storage at ...
