The difference between mold and yeast on Bengali red culture

Bangladesh Red
Culture
-based is a
medium
used in food to detect the total number of molds and
yeasts
bacteria, because it contains chloramphenicil, which inhibits the reproduction of the vast majority of bacteria, but does not inhibit
fill
and is therefore appropriate for counting mold and yeast.
so cultured how to distinguish between mold and yeast on the culture base?
If the test is tested with a coating method to count, then yeast culture 48 hours will form pink, round raised bacteria, many strains open the petri dish cover will also have a faint aroma, some yeast culture after more than 5 days will grow "silk" on its edge, At this time do not mistake it for mold, you can stain the mirror to observe, mold in the culture of 2-3 days began to reproduce mycelium, most of the mycelium is white or milky yellow, cultured 4-5 days after the end of the mycelium will produce a large number of spores, may be black, yellow, green and other colors.
If the test is counted by pouring, then yeast culture that grows inside the media for 48 hours will form pink, close to the diamond, with neat edges, and some will be round, and mold will form mycelium, culture 4-5 days at the end of the mycelium to form spores.
Again, the form of mold we can often see in life, such as bread after a long time mold, rice surface mold, fruit decay mold and other phenomena, are mold growth form.
if it is still not good to judge, the suspicious bacteria that grow inside can be picked out and re-routed on the Bengal red plate, cultured to observe its shape on the surface more well observed.
for mold and yeast staining, mold can choose lactic acid phenol cotton blue dye, yeast can choose 0.1% Lushi alkaline blue dye. Molds can take the form of mycelium and spores, and yeasts are larger oval or round cells.
