Abstract Anaerobic degradation of bioplastics is a controversial challenge. Size reduction must for while it requires significant amount energy, which lowers the overall energy efficiency system. On other hand, inoculum to substrate ratio has interaction effects in process. The present work aimed optimize these two parameters improvement through response surface methodology. central composite d...

The amount of environmental contamination brought on by the careless disposal plastic garbage has increased to 400 million tons every year a global scale. These synthetically generated traditional polymers are not easily biodegradable. This work was therefore undertaken isolate Bacillus subtilis from soil with potential produce bioplastic: Poly-ß-hydroxybutyrate (PHB). Samples were collected va...
