Lactic acid media selection
In skim milk agar, obtained outstanding bacterial colonies. The former gave the round white White-colored colonies irregular boundaries determined for a translucent colonies of bacteria in the flat Rather than large-scale undetermined Streptococcus bacteria colony boundaries. After anaerobic culture is
It is impossible to distinguish between these two types of colonies, because the milky, since the bacterial culture Ethyl lactate precipitated casein agar for M17, the incubation conditions, to be able to be identified,Only one colony, is greater in anaerobic (thickness) than the average diameter
Aerobic conditions (average diameter <1 mm). They look round shape, milky white, There are clear boundaries. All of these colonies is dedicated to S thermophilic, as it is to appear on Microscopic observation. For MRS agar, it is possible, but still difficult to distinguish between the two colonies Under anaerobic conditions. Is ferrous lactate first in the shape, white and clear boundaries and
Belongs to s. Streptococci. Others are round, determined boundaries, and subsp. L.delbrueckii correspond. Statistical analysis of the total microbial counts of lactic acid in the newly acquired cultural Recent media (Table 1) to allow the establishment of the average of the obtained skim milk agar in the incubation of the Parts, no significant difference (P> 0.01). Same results in the same two conditions MRS agar species is also obtained, compared with one of the four values can be found obtained from the MRS agar Data lower (P <0.01). S-M17 agar data regardless of thermophilic or eye excellent Yaang Aung under pressure differences are not large (P> 0.01).. When these data in the skim milk agar
MRS agar and compare the data obtained becomes low. Finally, the skim milk Joan
Fat and MRS agar close the data.
