    abstract = {Fifty ninelactic acid bacteria isolated from
Algeriangoat’s milk and previously selected according to
their technological properties. They were screened for
antimicrobial activity. Between 3258bacterial couples
brought into studies,we observe 747 cases of inhibitions
(22.93%). The results obtained show that the lactobacilli
have high spectrum of action. Thus, for the various
species: <i>Lc. lactis subsp. lactis</i> (40.1%); <i>Lc. lactis subsp.
lactis</i> biovar. <i>diacetylactis</i> (29.1%); Leuconostoc (25.8%);
<i>Streptococcus</i> (56.9%); <i>Pediococcus</i> (36.5%) and
Lactobacillus (13.5%). For the whole of the interactions
brought into studies, the lactobacilli inhibited 392 strains
of 1331 couples (29.5%); the other species have a more
reduced spectrum of action: Lactococcus (18.76%);
<i>Leuconostoc</i> (25.7%); <i>Streptococcus</i> (17.5%) and
<i>Pediococcus</i> (5.34%). Six strains showed inhibitory
activity in solid medium (well diffusion assay) when
tested against the effects of organic acid and hydrogen
peroxide were eliminated. These strains did not show
inhibitory activity after treatment with proteinase K,
trypsin or &#945;-chymotrypsin. <i>Lactococcus lactis</i> subsp.
lactis LCL01 produced a heat stable substance with a
proteinaceous nature and with bactericidal action,
suggesting a bacteriocin-like. Only <i>Lb. plantarum</i> LPL01
inhibit <i>E. coli</i>.}
