Assessment of biodegradation activity of selected strains of lipolytic bacteria
Languages of publication
The existing experience point out to the fact that the application of microbiological methods to degrade fat contained in organic waste is the most effective method of their biodegradation. The efficacy of this method depends on the rational screening of fat biodegrading microorganisms. The examination assesses the lipolytic activity and the efficacy of waste oil biodegradation by selected lipolytic bacteria. The examination was carried out in laboratory conditions and it assessed such values as lipolytic activity, total bacteria count including lipolytic bacteria and the amount of fatty substances. Both archived strains and strains isolated from organic waste were used in the examination. The highest lipolytic activity was manifested by the bacteria of the Bacillus and Pseudomonas strains, including Bacillus subtilis, Pseudomonas fluorescens and Pseudomonas fragi. For those strains, the fatty substance reduction after 7 days of culturing was between 50 and 60%.
