Growth performance of Spirulina platensis in supernatant of digested rotten guava

This study was performed to evaluate the culture potentiality and growth performance of Spirulina (Spirulina platensis) in supernatant three different concentrations digested rotten guava (DRG) Kosaric Medium (KM) as control. The consisted guavas, such 20 (T1), 40 (T2) 60 (T3) were allowed digest under aeration. After 34 days, replications showed reddish white-colored screened taken a 2.0 L conical flask. Then, inoculated grow these media (DRGM) with addition micronutrients KM 9.0 g/L NaHCO3 for 14 days. cell weight attained at maximum 12.43±0.10 mg/L (dry wt. basis) KM, followed by 0.818 ± 0.002, 0.815 0.0014 0.809± 0.0011 60, 40% DRGM, respectively on 10th day culture. A similar trend also observed case specific rates (based chlorophyll a) total biomass (mg/L) Spirulina. Cell had highly significant (P<0.01) correlation content (r= 0.746) 0.742) results that grown 60% DRGM significantly higher than 20% (T1) (T2).
