Conclusions<br />

There were tested 5 commercial preparations with aim to<br />

find out, if they have lipolytic activity and if they have ability to<br />

degrade fats. Samples were cultivated at the agar plates and submerged<br />

cultivation in Erlenmeyer flasks. The comparison results<br />

of lipolytic activities of both cultivations were followed. The<br />

submerged cultivation, after 2 days of EP demonstrated approximately<br />

the same value of activities as cultivation on agar<br />

plates after 7 days.<br />

All tested EP had ability to degraded olive oil and released<br />

fatty acids. The best degrading ability had EP 1, the<br />

lowest ability EP 4.<br />

It was made a laboratory verification of function 5 EP<br />

for liquefaction and decomposition of fats and oils in the<br />

wastewater. On the basis obtained by dates, it might be choosen<br />

the best EP for suggestion technology. Biotechnology<br />

effects were made out for EP 1 and 5, the lowest efficiency<br />

was made out by EP 4.<br />
