according to a new study, the leaves of the bean tree contain antibacterial substances that
inhibit the growth
listeria
.Nadhern Aissani
et al. tested the ability of caron leaves methanol extract (
MECL
)
to inhibit
various
microorganisms.writing in the American Chemical Society's Agricultural and Food Chemistry,said they
a test has shown that
bean leaf extract can effectively inhibit the growth of Lester bacteria under laboratory conditions."seeking

substances this experiment is for
a

that seeks to benefit
fedal storage
and
its purpose is to partially or completely replace the current antimicrobial chemicals.March

Researchers
collected long-horned bean leaves from
Italy
Cagliari
and dried them at room temperature without light. Seal in a paper bag and store at room temperature and in dark conditions until used.they found that by micro-dilution of liquid media,
chloromethane (
MECL
)
concentrations of
28.12μg/mL
. inhibited the growth of listeria.the concentration of yang meiyan and unethic acid inhibited the growth of listeria was
450sg/mL

-inhibited
concentrations of esters and isocleosides were
225μg/mL
and
112.5?g/mL
.researchers said: "The inhibition effect of
concentrations on this bacteria can be characterized as
an inhibition model characterized by a recovery phase (
a
), which shows a lower growth rate
if
compared to the control group; "" In order to analyze the growth rate of listeria inhibitors (
MECL
), the provisional bacterial
amount is
103 CFU/mL
,
and adds the
MECL
concentration we want, agar has

" Repeat the experiment in different plates, dilute
every three hours,
with blank groups without extracts. The bacteria
overnight
37 degrees C, and then counted
the number of
bacteria
.the experiment used E. coli, salmonella genus, Glucose-negative copper-green protocytobacteria strains,
L

.researchers say the next step
will be
to study the
inhibition of the activity of cartilage leaves methanol in bio-living
