Erguven, Gokhan Onder; Bayhan, Hurrem
The study is about the removal of herbicide Trifluralin as COD parameter and monitoring the population dynamic of isolated cultures. These cultures were isolated from soil samples taken from these areas for their identifications before the use of herbicide. Removal of Trifluralin was determined by microbiological degradation with these produced bacteria and fungi in liquid media. With these growing bacteria and fungi, removal rate by bioremediation method studies were carried out. In addition to biodegradation mechanism, with the measurements of the turbidity; the colony number of microorganisms is monitored with isolated bacteria and fungi species. The removal efficiency for Bacillus simplex was 95% and Clostridium tetani species was 86%, by the fungi Penicillium simplicissimum, and Metacordcyceps chlamydosporia species, were 59% and 80% respectively in five days. Bioremediation study results have shown differences with respect to species in liquid media. Degradation time of these herbicides in liquid culture media with isolated cultures varied between 5 min. and 135 min.

Bioremediation is the use of microorganisms to degrade environmental contaminants (pesticides, polyaromatic hydrocarbons etc.) into less toxic forms or compounds. In this study microbial biodegradation of trifluralin was performed in liquid media with 11 different types of identified fungi and bacteria cultures and their mixtures in agiated culture media. The isolated fungi and bacteria mixtures showed the highest degradation, reaching 93% in the chemical oxygen demand (COD) parameter in four days and 82% as trifluralin active ingredient in five days. Bacteria and fungi mixtures achieved 69% and 66% degradations of trifluralin active ingredient respectively. In the fungi studies, the best removal was achieved by M. Chlamydosporia at 80%, in the bacteria studies, the best removal was achieved by Bacillus simplex about 95% in five days. These different removal rates were due to the microbial differencies.
