 Although a high yield was not produced, this displays the early use of genetic engineering for production of biodegradable plastics.Efforts are still being made in the direction of biodegradable plastic production through genetic fabrication and re-design.A paper published in 2014 titled “Genetic engineering increases yield of biodegradable plastic from cyanobacteria” outlines procedures conducted to produce a higher yield of PHBs that is industrially comparable.
