The effects of light intensity, inoculum size, and cell immobilisation on the treatment of sago effluent with Rhodopseudomonas palustris strain B1

A study was carried out to determine a suitable light intensity and inoculum size for the growth of Rhodopseudomonas palustris strain B1. The pollution reduction of sago effluent using free and immobilised R. palustris cells was also evaluated. The growth rate in glutamate-malate medium was highest...
