Abstract
In recent years. there are increasing levels of pollution caused by industrial wastewater. Sago effluent discharged into the river contains hazardous compound, toxic chemical and organic materials. In order to overcome this problem, organic materials from sago effluent must be removed by using submerged fermentation. R. oligosporus was grown in sago effluent to treat waste water and convert organic matters into useful product. In this study, different amount of aerations were tested for the growth of R. oligosporus in sago effluent which were 0.00, 0.50. 0.75 and 1.00 vvm. Aeration of 1.00 vvm was identified to produce the highest biomass production which was 77.0% or 104.333 g/L for wet biomass and 66.2% or 3.790 g/L for drv biomass and subsequently 0.75, 0.50 and 0.00 vvm. This shown that the microorganisms need sufficient aeration for their growth. There were three analysis conducted in this study which were phenol-sulphuric, nitrate and nitrite analysis. The phenol-sulphuric analysis revealed the total carbohydrates in the sample decreased along this study from 19.919 g/l, to 0.334 g/l. for 1.00 vvm which was 98.3%. In addition, this study showed the concentration of nitrate was decreased from 0.267 g/I_ to 0.260 g/L and nitrite was decreased from 0.056 g/l, to 0.031 g/I. against the day of fermentation. It proved that the growth of R. oligosporus in sago effluent had the potential to treat the waste water. At the same time, this study can produce beneficial product which was high protein fungal biomass (HPFB) which can used as animal feedstock. It can he concluded that this study could be the solution to the pollution problem as it can minimize the damage on environment.
