A total of 59 LAB isolates were investigated, of which 56 strains showed distinct antimicrobial activity against Salmonella enterica ATCC [43971.sup.T],
Micrococcus luteus ATCC [4698.sup.T] and Escherichia coli ATCC [11775.sup.T] indicators.
It is important to note that the best antibacterial activity of SA-EAS was observed against Bacillus subtilis and
Micrococcus luteus ATCC 9341 while SA-PES exhibited strong activity against Corynebacterium diphtheriae.

Among Gram positive bacteria (table 5) the most frequent genera were Staphylococcus (32 strains),
Micrococcus (26 strains) and Bacillus (28 strains), isolated from 24.0%, 21.9% and 18.8% of the samples; these genera were considered of low frequency (10 [less than or equal to] 25%), but close to the value that would consider them as "frequent" (25 [less than or equal to] 35%, Azedo Loureiro et al.
Dr J Nuzum, in 1925, cultured a minute gram-positive
micrococcus unidentified (but possibly a member of the streptococcus group) from a breast tumour.
The causative organism (designated ROG140) was initially identified as
Micrococcus sp.
*
Micrococcus luteus was used as a surrogate for Gram-positive cocci, because it is similar in size, shape, and cell wall composition to staphylococci, streptococci, and enterococci.
The antimicrobial compound was bactericidal and bacteriolytic against Escherichia coli V517, bacteriostatic against
Micrococcus luteus and fungistatic against Saccharomyces cerevisiae.

micrococcus. The only major differences after 2 weeks were increases in S.
DNA damage-specific endonucleases from
Micrococcus luteus have been used previously in combination with sucrose gradient sedimentation (8), alkaline elution (9), and alkaline unwinding (10) to reveal base damage inflicted by ionizing radiation.
