The yeast analyzed here has been "harvested" several times and was shipped during hot weather.
Average Viability: (49.02+55.74)/2=52.38%
Deviation in viability = 55.74-49.02=6.72%
Average Settled Slurry Cell Density: 575 million cells per ml
Deviation in Cell Density: 156 million cells per ml
Viability is very low (This may have been due to heat exposure during shipping.)
Cell Density is low. This is usual considering that there is very little non-yeast content. The light packing may be characteristic of the strain or may be caused by the harvesting method.
No visible motile bacteria.
No pseudohyphae. (Lack of pseudohyphae, as is the case here, indicates that the yeast was not grown in a stressful environment.)
Very little non-yeast material.
No noticeable flocculation. (This is very unusual. It could be a characteristic of this strain or it may have something to do with harvesting methods used for the slurry. It also may explain the low cell density.)
Viability = 50/(50+52)= 49.02%
Viability = 34/(27+34)= 55.74%
dilution factor is 42ml/0.8ml=52.5
