“…Photosynthetic bacteria typically have lower process productivity than heterotrophic bacteria because the cell densities achieved are low (Kobayashi and Kurata, 1978). This is in agreement with Ponsano et al 2003 where the process productivity of Rhodocyclus gelatinosus R1 was around 0.072 g/L.day. With regard to cell yields with normal heterotrophs growing with aerobic growth conditions 50% of organic carbon can be converted to biomass, whereas with anaerobic conditions only 5% is converted into biomass (Speece, 1983).…”

“…The protein content of PNSB strain DK6 (65.2%) was similar to that of Rhodocyclus gelatinosus R1 (67.7%) grown with poultry slaughterhouse wastewater under anaerobic light conditions (Ponsano et al 2003). Isolate DK6 has therefore a great potential for use as SCP (Sasaki et al 1991;Sasikala and Ramana, 1995).…”

“…This system presents two advantages: first its high productivity and second its non-toxic nature as K. marxianus is recognized as a GRAS microorganism. This biotechnology application could be successfully applied when different kinds of industrial wastes are used as substrates, as has been reported using a poultry slaughterhouse wastewater to produce Rhodocyclus gelatinosus reducing the chemical oxygen demand (Ponsano et al, 2003).…”

“…Alguns pesquisadores têm utilizado recursos biotecnológicos para o tratamento de efluentes industriais, tais como o uso de bactérias fotossintetizantes, como Rubrivivax gelatinosus, que possuem a capacidade de reduzir a carga poluente desses resíduos (Ponsano et al, 2002a(Ponsano et al, , 2003(Ponsano et al, , 2008Lima et al, 2011). Lima et al (2011) caracterizaram o crescimento de R. gelatinosus em efluente de indústria de pescado, observando uma redução da Demanda Química de Oxigênio em 52%.…”

“…Ponsano et al (2002a) isolaram e caracterizaram quatro culturas de R. gelatinosus a partir de águas residuárias provenientes do abate de frangos e identificaram seus carotenoides como sendo da série espiriloxantina alternativa. Posteriormente, Ponsano et al (2003) investigaram a composição centesimal da biomassa de R. gelatinosus e encontraram elevada quantidade de proteínas e aminoácidos essenciais. Os carotenoides da biomassa de R. gelatinosus foram capazes de promover a elevação da intensidade da cor vermelha de gemas de ovos quando adicionados à ração de galinhas poedeiras (Polonio et al, 2010).…”
