Original Abstract

The valorization of agricultural waste is a sustainable way of how to utilize renewable resources wisely. Grape pomace is a by-product of the manufacturing of the must. The potential of Cupriavidus necator, Halomonas halophila and Halomonas organivorans to produce poly(3-hydroxybutyrate) (PHB) by using oil and fermentable sugars derived from grape pomace has been studied. C. necator proved to be the best producer of PHB when utilizing grape pomace extract as a carbon source. After 29.5 h of fermentation of C. necator in 2-L bioreactor, PHB titers reached 8.3 g l−1 and 63 % PHB content in bacteria cell dry mass. The average molecular weight and the polydispersity of accumulated polymer was 512.2 kDa and 1.2, respectively. In addition to fermentable sugars, this work indicates that oil, pigments, phenolics, lignin and cellulose can be isolated from seeds and the rest of the grape pomace to support the cascading utilization of agricultural waste and natural valuable resources recovery.
