| dc.description.abstract | Plastics are used in almost every part of modern life, from making aeroplanes, cars, and buildings to making clothes, shoes, packaging for food and drinks, and medical devices. As a result, plastic waste is gathered globally, worsening the effects on the ecosystem. Synthetic plastics/conventional plastics takes many years to disintegrate in nature, and incineration produces toxic substances and raises CO2 levels in the atmosphere, causing issues like global warming. As a result, alternatives to petrol-based polymers are being sought. Polyhydroxyalkanoates (PHAs) have been proposed as a feasible substitute for petrochemical-based polymers because of their biodegradable nature. In the present study, Cupriavidus malaysiensis USMAA1020, a Gram-negative bacterium was able to produce biodegradable polymer P(3HB-co- 3HV) by utilizing glycerin pitch which is a by-product of the biodiesel synthesis obtained during the transesterification as low-cost feedstock. The aim of the research was to screen various concentrations of glycerin pitch (5 g/L, 10 g/L, 15 g/L, 20 g/L, 25 g/L), 1-pentanol (0.03 wt% C, 0.06 wt% C, 0.09 wt% C, 0.12 wt% C), ammonium sulfate (0.8 g/L, 1.1 g/L, 1.4 g/L, 1.7 g/L, 2.0 g/L), and different precursors nonaoic acid, valeric acid, propionic acid, with respect to 1-pentanol at concentration of 0.06 wt%C. To enhance the production of PHA, oleic acid concentrations was used as a secondary carbon source. | |
