Optimization of biomass yield of Spirulina platensis grown in petha (Benincasa hispida Thunb.) waste in different culture conditions.

摘要

The growth of Spirulina platensis in terms of dry biomass was evaluated in standard (CFTRI) medium supplemented with different concn (10-60%) of Benincasa hispida waste extract (PWE) at different temp., pH, agitation and light intensity. Results showed that the max. growth rate measured in terms of biomass (dry wt.) and chlorophyll a content was recorded as 2.337 g/l and 21.209 mg/g, respectively, where cultures were illuminated under 3 Klux fluorescent light at 30 +or- 2 degrees C, pH 9.5 +or- 0.1 and agitated for 2 min, 3 times a day. Results indicate that favourable culture conditions during Spirulina culture could be instrumental for good biomass and chlorophyll production in PWE.
