Key Points

This research aims to understand how different carbon sources affect hydrogen sulfide production in specific algal strains.
Cultivated two strains each of Desulfovibrio spp. and Desulfotomaculum spp.
Used lactate, succinate, or glucose as carbon sources in a basal medium.
Assayed hydrogen sulfide levels via iodometric titration every two days over three weeks.
Lactate was identified as the most effective carbon source for hydrogen sulfide production.
Maximum H₂S-S production was 30 mg/l during 20 days of incubation.
Desulfotomaculum spp. showed higher metabolic activity than Desulfovibrio spp..
Synergism in mixed cultures using glucose improved H₂S production compared to individual strains.

An investigation reveals carbon source effects on hydrogen sulfide production in algal cultures, indicating metabolic differences among strains.
