Thermoplastic starch wastes are converted and stored into acetone through butanol in a depressurised digester

摘要: Abstract A biofilm containing both hydrolytic fermentative bacteria and acidogenic (including acetogenic acetoclastic bacteria) was developed for the treatment of plastic wastes in a two-phase, batch digester. The biotransformation further degradation were electrochemically observed. It found that organic initially fermented single-phase (i.e. liquid phase) digester, where it entirely obeyed microbial growth kinetics accumulating acetate. As carbonates produced vaporised, became two-phase fermentation (gas liquid) volatile fatty acids (VFAs), proton driving force based on Le Chatelier’s principle. Interestingly, as digester depressurised to saturated vapour pressure water, accumulated VFAs rapidly transformed into acetone via butanol, so forms not observable. extreme conditions, feeds converted stored acetone, butanol.
