초록

A method for inexpensive and efficient PHA biosynthesis includes operating a sequencing bioreactor in alternating phases of nutrient deprivation and carbon feedstock deprivation to select for robust PHA-producing microbes. Preferably, the bioreactor is operated in a non-sterile manner with mixed cultures of methanotrophs. The method also preferably uses periodic biomass-wasting (PHA harvesting) at the end of the carbon feed phase, gradually lengthening the time period of carbon deprivation phase to create a penalty for rapid PHA degradation and incentive...

The invention claimed is: 1. A method for producing PHA polymers, the method comprising:performing in a bioreactor aerobic microbial biosynthesis of PHA polymers from a feedstock using mixed bacterial cultures in non-sterile conditions, wherein the feedstock comprises anaerobic degradation products;extracting the biosynthesized PHA polymers to obtain PHA granules; andrepeatedly cycling the bioreactor through a first period and a second period;wherein the first period comprises maintaining in the bioreactor excess feedstock and limited nutrients;wherein t...
