Cottage cheese

During my workshop at GGDSD COLLEGE chandigarh I took cottage cheese and suspended it in  water and centrifuged it at 2000 rpm for 2 mins.After 2 mins , I prepared a smear from the supernatant and observed it under foldscope .

First I stained the smear with methylene blue and observed cocci . They may be the normal microflora of the cheese like Lactobacillus, Lactococcus, Leuconostoc, Pediococcus, Streptococcus.  I also found some large sized microbe that I suspected to be yeast. To confirm it, I stained my sample with lactophenol cotton blue.
