title: Phototrophic growth of Rubrivivax gelatinosus in poultry slaughterhouse wastewater.
abstract: Rubrivivax gelatinosus was grown in Pfennig's synthetic medium (PM) and in treated wastewater from poultry slaughterhouse (TW) to assess growth profiles for biomass production. Cultures inoculated at 1% (v/v) were grown under anaerobiosis at 30+/-2 degrees C and 1400+/-200 lux for 12 days. Regular absorbance curves for R. gelatinosus were found both on PM and TW. On PM, the highest dry weight of biomass, 0.39 gL(-1), was achieved in the 216-h culture and the highest specific growth rate of 0.2960 h(-1) occurred in the 24-h culture. On TW, the highest biomass of 0.57 gL(-1) was also obtained in the 216-h culture and the highest specific growth rate, 0.1970 h(-1), was achieved in the 48-h culture. For productivity and chemical oxygen demand investigations, the cultivation was accomplished in the TW under anaerobiosis at 32+/-2 degrees C and 4000+/-500 lux, for 10 days. Productivity was 0.085 g biomass (d.w.) L(-1) day(-1), with a COD decrease of 91%.
