Production of biomass and extracellular 5-aminolevulinic acid by Rhodopseudomonas palustris KG31 under light and dark conditions using volatile fatty acid

Physicochemical profile of microbial-assisted composting on empty fruit bunches of oil palm trees

“…ALA can be easily converted into porphobilinogenin the presence of ALAD (Lee et al 2003;Chung et al 2005). It is important to note that the decrease of ALA at day 64 might be also contributed by the poor stability of ALA as reported by Choorit et al (2011). The stability of ALA produced by Rhodopseudomonas palustris KG31 could be decreased from 36 to 75 % at room temperature.…”

“…Previous studies reported that many photosynthetic bacteria such as Rhodopseudomonas palustris, Rhodobacter sphaeroides, Chlorella vulgaris, Chlorella regularis, and Chlostridium thermoaceticum attributed to the production of ALA (Liu et al 2014). Glycine and succinate are the major substrates for ALA production (Choorit et al 2011;Yang et al 2013;Liu et al 2014). In the present study, EM-treated EFB showed the increasing trend of ALA production, whereas the production of ALA in CTL was not stable as presented in Fig.…”

Genetic redundancy in iron and manganese transport in the metabolically versatile bacteriumRhodopseudomonas palustrisTIE-1

“…Other strains of Rhodopseudomonas have also been used to produce value-added compounds (29)(30)(31)(32)(33)(34). Production of such biomolecules is controlled by intracellular electron availability, which in turn is modulated by the action of various Fe-containing proteins.…”

“…Depending on the availability of different energy and carbon sources, TIE-1 can perform multiple modes of metabolisms such as photoautotrophy, photoheterotrophy, chemoautotrophy and chemoheterotrophy (26)(27)(28). Similar to the other strains of Rhodopseudomonas that have been used to produce value-added compounds (29)(30)(31)(32)(33)(34), TIE-1 can also produce compounds such as bioplastics and biofuels under various growth conditions ((35), Bai et al, submitted for publication). Electron transfer during the synthesis of these compounds requires Fecontaining proteins, such as cytochromes.…”

Breakdown of food waste by anaerobic fermentation and non-oxygen producing photosynthesis using a photosynthetic bacterium

“…Rhodopseudomonas has also been used successfully to break down palm oil mill waste (Suwansaard et al, 2009). R. palustris is also very efficient in breaking down fatty acids which would arise from the hydrolysis of cooking oils (Choorit et al, 2011). Breakdown of oils and greases are a major environmental problem and Rhodopseudomonas can break down both the glycerol and fatty acid components.…”
