NOVELTY - Method for phototrophic production of polyhydroxyalkanoates from organic waste, involves anaerobically digesting organic waste for a digestion period to generate an organic acid enriched feedstock, inoculating organic acid enriched feedstock with a bacterial consortium, fermenting the inoculated organic acid enriched liquor through at least one light phase period and one dark phase period to generate a polyhydroxyalkanoate enriched biomass, and harvesting the polyhydroxyalkanoates from the polyhydroxyalkanoate enriched biomass.    USE - The method is useful in phototrophic production of polyhydroxyalkanoates from organic waste (claimed).    DETAILED DESCRIPTION - Method for phototrophic production of polyhydroxyalkanoates from organic waste, involves (a) (i) anaerobically digesting the organic waste for a digestion period to generate an organic acid enriched feedstock, (ii) inoculating the organic acid enriched feedstock with a bacterial consortium containing at least one species of bacteria from at least four of the bacterial families chosen from purple bacteria Chromatium, purple non-sulfur bacteria, green sulfur bacteria, filamentious green bacteria and colorless sulfur bacteria, to produce an inoculated organic acid enriched liquor, (iii) fermenting the inoculated organic acid enriched liquor through at least one light phase period and one dark phase period to generate a polyhydroxyalkanoate enriched biomass, and (iv) harvesting the polyhydroxyalkanoates from the polyhydroxyalkanoate enriched biomass, or (b) (i) performing the above-mentioned steps (a)(i) and (a)(ii), (ii) fermenting the inoculated organic acid enriched liquor with exposure to radiant energy for a light phase fermentation period to generate a glycogen enriched biomass, (iii) fermenting the glycogen enriched biomass in the absence of radiant energy for a dark phase fermentation period to generate a polyhydroxyalkanoate enriched biomass, and (e) harvesting the polyhydroxyalkanoates from the polyhydroxyalkanoate enriched biomass.
