The chlorophyll profile of C. pyrenoidosa and S. abundans with
different inoculum size is presented in Fig. 1. It can be noted
from Fig. 1(a) that the maximum chlorophyll content in raw
sewage sample for C. pyrenoidosa with inoculum concentration
of 10% and 20% was observed as 11.4 mg/l and 7.73 mg/l in
4th day and 7th day, respectively. Similarly, from Fig. 1(b),
it can be noted that the maximum chlorophyll content in
raw sewage sample for S. abundans with inoculum concentration
of 10% and 20% was observed as 7.23 mg/l and
7.12 mg/l in 6th day and 7th day, respectively.
