some prokaryotes
mammalian muscle cells
yeast
Yeast causes fermentation.
these are those bacteria which are not able to ferment lactose sugar hence are called non lactose fermenting or negative lactose fermenting organisms.
Salmonella, Shigella Organisms that ferment lactose display "nucleated colonies" - colonies with dark centers.
No Proteus Vulgaris does not ferment lactose
Yes. Therefore it grows on CLED media together with other gram negative organisms so you would see yellow colonies.
Yes it does.
yes, it does
coliform ferment lactose and are non pathogenic, non-coliform do not ferment lactose and are pathogenic (true pathogens)
Yes.
no, it shows negative for lactose fermentation on MacConkey's agar
Fecal coliforms have the ability to ferment lactose at 44C +/- 0.05C while regular coliforms ferment lactose at 35C-37C
No, it doesn't. After performing the Lactose fermentation test, the isolated colonies will turn yellow meaning that the test was negative.
no it does not ferment lactose, therefore is not a coliform
