Abstract

Istraživanje aktivnosti mješovite bakterijske kulture u razgradnji atrazina provedeno je usporedno u tekućoj podlozi i u tlu pri temperaturama 10°C i 30°C. Za ta istraživanja odabrana je kultura podrijetlom iz sedimenta uzetog u kanalu tehnološke otpadne vode iz sinteze atrazina. Analizom kinetičkih pokazatelja utvrđena je razgradnja atrazina u svim eksperimentalnim uvjetima te je ocjenjeno da istraživana kultura pokazuje bolju aktivnost u razgradnji atrazina od do sada opisanih pojedinačnih bakterija i mješovitih kultura. Dobar rast i preživljavanje bakterija u tlu te utvrđena katabolička aktivnost istraživane kulture ukazuje na njenu potencijalnu primjenu za ubrzanje razgradnje atrazina u onečišćenom okolišu.

Abstract (english)

Research of activity of a mixed bacterial culture in atrazine degrading was conducted in shake culture and soil at temperatures of 10°C and 30°C. A bacterial culture, from the sediment of technological wastewater canal from atrazine synthesis, was chosen for this research. With the analysis of kinetic properties the atrazine degradation was established in all experimental conditions and it was noted that the researched bacterial culture has a higher activity in atrazine degrading then any until now described single cultures and mixed cultures. Good growth and the survival of bacteria in soil and the established catabolic activity of the researched culture indicates it′s potential application for acceleration of atrazine degradation in the polluted environment.
