| Abstract: | Ten strains of purple non-sulfur photosynthetic bacteria, isolated from wastewater produced by a concentrated latex processing factory, were cultivated in a wastewater medium without supplementation. After 40 h cultivation, one strain SS51, decreased the COD content of the wastewater by 34%. Optimal ratio of mixed-cultivation between SS51 and SY40 was 14:7 (ml/ml), and the COD content of the wastewater was decreased by 57%. Both strains were identified as Rubrivivax gelatinosus. |
