Abstract
In this study the technical feasibility of using cider by-products as a substrate for the production of medium chain length polyhydroxyalkanoates (mcl-PHAs) by Pseudomonas putida KT2440 is demonstrated. The untreated apple pomace was found to be composed of two main residual sugars, glucose and fructose, making it a promising cheap growth substrate. A PHA concentration of 1.1 g L−1 and a PHA accumulation of 25.5% were obtained in flask experiments using apple pomace as the sole carbon source without any pretreatment, employing a fed batch strategy. The biopolymer was extracted from the biomass and a detailed characterization was carried out. The solution-casted film was found to be a mcl-PHA copolymer composed by different saturated and unsaturated ester monomers with elastomeric characteristics making it suitable for applications in biomedicine or the processing of value added co-products such as environmentally friendly adhesives or biodegradable films for agricultural purposes.
