Agro-industrial oily wastes as substrates for PHA production by the new strain Pseudomonas aeruginosa NCIB 40045: Effect of culture conditions

PHA accumulation ranged between 66.1% when waste-free fatty acids from soybean oil (WFFA) were used as carbon substrate, 29.4% when waste frying oil (WFO) was used and 16.8% when glucose was used. Depending on the substrate supplied a wide range of components was observed. Major saturated or unsaturated components of the polymer found were C10:0, C12:0 and C8:0 or C12:1 and C14:1, respectively. When glucose was used as carbon substrate C9:0, C11:0 and C16:0 were found.
