Waste Materials in the Microbial Production of Lactic Acid and Butanol

Popis výsledku v původním jazyce

The objective of our project was to design and optimize the process of microbial production of lactic acidor butanolusing an alternative, inexpensive substrate with achievement of lactic acid or butanol high yield. Fermentations were performed using a low-cost source of carbon, hydrolysate of straw or molasses, and a low cost source of nitrogen, hydrolysate of chicken feather. Straw and feather werehydrolysed with sodium hydroxide at a concentration of 0.6 %by weight. In further experiments the hydrolysate ofchickenfeather (hydrolysed with 20% sodium hydroxide) was used as a neutralizing agent.Homofermentative strain Lactobacillus casei (for a lactic acid production) and solventogenic strain of Clostridium beijerinckii(for a butanol production)wereusedas production microorganisms. Obtained data showed that usageof complete medium containing featherand strawhydrolysateswas a good choice for these purposes and that molasses can be used as an additionalsource of carbon in fed-batch fermentation.Chicken feather hydrolysate (NaOH 20 % by weight) couldbe used to neutralize formed lactic acid. From the results obtained, it is obvious thatboth strainscan utilize pentoseswhich is indisputable advantage if lignocellulose hydrolysate is used.
