| description | Proper nutrition plays a key role in the growth of fish. However, limited supply of raw material
for fish feed has posed problem for the ever-growing Aquaculture. Waste water from food
industries (e.g. diaries and slaughterhouses) contains considerable amounts of proteins and fats to
be used as fish feed. Similarly, glycerol which is a by-product in biodiesel production can be used
as carbon source by yeast. Linseed oil can be useful as a source of fatty acids.
In this study we investigate the potential of waste from paper and beer industries as a growth
medium for yeast. We used two different concentrations of Glycerol and Linseed oil. Media was
inoculated with yeast and cultured for 48 hours. To determine the growth of yeast, OD (Optical
Density) was measured for each sample at three hours intervals.
Our results show that waste from beer industry is very promising as compared to waste from
paper industry for the growth of yeast. Moreover, all strains of yeast showed better growth when
lower concentrations of glycerol and linseed oil were added to beer water as compared to high
concentrations. |
