Evaluation of mexican avocado (Persea americana) seed starch as a carbon source for PHA production

The study evaluates Mexican avocado (Persea americana) seed starch as an economical carbon source to produce polyhydroxyalkanoates (PHA). Extraction and quantification methods were used to determine the efficiency of starch extraction and its acid hydrolysis with 0.4 M HCl, releasing up to 46.7% glucose. Spectrophotometric techniques, such as the turbidity test and the DNS method, analyzed bacterial growth and glucose consumption. The results indicate that this agro-industrial by-product is a viable alternative for PHA production, with the help of a suitable microorganism and a viable fermentation mode and may be the future of biopolymer production.
