Summary: The goal of this work is to investigate how mixed culture of microorganisms degrade organic matter when molasses slops is the model substrate. After the continuous work of the reactor is obtained, beside molasses slops, the waste water from various productions (antibiotic, sorbitol, chlorhexidine,chemical synthesis) will be used. If such waste water hinders the biological degradation of molasses slops, it will be pretreated. The parameter will be done by physical and chemical methods in such a way that the organic matter is recycled, translated into biodegradable form or totally destroys. The mixed microbial culture from anaerobic reactor, ie. its facultative anaerobic members will be isolated and identified according to their morphological, cultural and physiological characteristics.

Keywords: Mixed culture, anaerobe consortium, facultative anaerobe, molasses slops, biogas, volatile acids, microbial degradation, pretreatment.

Research goals: The goal of the proposed project is to obtain stable anaerobic culture able to pure the waste water from the Bakers' yeast production. Such mixed culture with precisely determined parameters will be used as a model culture for the treatment of waste waters from sorbitol, chlorhexidine, antibiotic, vitamin C ect. productions both separetely and their total mixture. In such a way, the real parameters will be obtained and they will prove whether it is possible to treat all the waste waters on the location Savski Marof at once or will it be necessary to pretreat the waters. Isolated and defined microorganisms are collected in the bank of microorganisms what will enable the breeding of the required defined mixed cultures.
