“…It showed the highest sequence similarities with P. resinovorans ATCC14235. These results are in agreement with previous finding reported by (Kopytko et al, 2002;Karpouzas et al, 2005;Belal et al, 2008;Derbalah and Belal, 2008;Megadi et al, 2010;Belal and El-Nady, 2013). It was found that enrichment culture technique led to the isolation of two bacterial strains, which were able to degrade different pesticides rapidly in liquid cultures.…”

“…The temperature 30°C appears to be the optimum for growth of the bacterial strain as well. The obtained results are in agreement with those reported by Belal and El-Nady (2013) who found that the optimum pH and temperature for pendimethalin degradation by Pseudomonas putida were 7 and 30°C, respectively.…”

“…The nitro group reduction and oxidative N-dealkylation destroys the herbicidal activity of pendimethalin, leading to its detoxification (Singh and Kulashrestha, 1991;Kole et al, 1994;Megadi et al, 2010). Belal and El-Nady (2013) found that Pseudomonas putida degraded pendimethalin completely in mineral salt medium.…”

“…Soil microorganisms that are repeatedly exposed to pesticides may develop new capabilities to degrade such chemicals (Vidali, 2001). There are some reports on the degradation of pendimethalin by microorganisms comprising Azotobacter chroococcum, A. vinelandii, Bacillus circulans, B. megaterium Pseudomonas putida and Phanerochete chrysosporium (Megadi et al, 2010;Belal and Hassan, 2013;Belal and El-Nady, 2013;Belal et al, 2014). The success of bioremediation depends not only on the high degradation ability but also on the stability of active microorganisms under varied conditions, such as changes in pH and temperature (Pattanasupong et al, 2004;Belal and Hassan, 2013;Belal and El-Nady, 2013).…”

Therefore, it is necessary to investigate the effects of various environmental factors on the growth ability of the tested microorganisms (Pattanasupong et al, 2004).…”

A b s t r a c t A r t i c l e I n f oBiodegradation of the selective herbicide pendimethalin which is used to control most annual grasses was investigated in water and soil. A pendimethalin degrading bacterial isolate (designated strain E20) was isolated using enrichment technique from wheat soil previously treated with the herbicide pendimethalin on the basis of morphological, physiological and genetical (16s rDNA) tests, this bacterial isolate proved to be identified as Pseudomonas resinovorans E20. Results showed that the optimum pH and temperature for the growth of pendimethalin degrading strain were 7 and 30°C, respectively. Additional carbon sources (glucose, lactose, starch, carboxymethyl cellulose and phenol) decreased pendimethalin degradation. Pseudomonas resinovorans E20 was used to remove pendimethalin from aquatic system with half-life of 5.9 days. Pendimethalin halflife was 49.2 days in untreated mineral liquid medium as control. Pseudomonas resinovorans E20 was also evaluated for degradation of pendimethalin in clay soil with half-life of 5.004 days, its half-life was 66.9 days in untreated clay soil. The obtained results illustrated that pendimethalin treatment reduced all measured plant features (plant height, root length, xylem vessels diameter, thickness of phloem tissue, vascular bundle as well as vascular bundle width) in comparison to the other treatments. On the other side, treatment with Pseudomonas resinovorans E20 led to improving and increasing the above investigated parameters. Evaluation of the genotoxic effects of pendimethalin on the genetic material of Vicia faba plants revealed that, the highest abnormal mitosis percentage (63.28%) was recorded for pendimethalin treated plants. On the other hand, Vicia faba plants treated with the bacterial strain Pseudomonas resinovorans E20 decrease the abnormal mitosis percentage which reached to 21.35% in comparison with the control treatment which gave a percentage of 3.85%. This indicates the degenotoxic effect of this bacterial strain pseudomonas resinovorans E20. At the biochemical genetic level, the two treatments (pendimethalin and pseudomonas resinovorans E20) induced some changes in protein banding patterns of Vicia faba plants. These changes included the disappearance of three protein bands with MW′s of 265, 175 and 40 KDa after treatment with the herbicide pendimethalin alone and appearance of the same bands after treatment with Pseudomonas resinovorans E20 bacterial strain.

In this study, we aimed to find out the biodegradation efficiency of some soil fungi types on herbicide acetochlor with acetochlor active material, chemical oxygen demand (COD), biochemical oxygen demand (BOD) and total organic carbon (TOC) parameters. We also try to determine the population dynamics of these fungi via turbidity. The fungi cultures were isolated from agricultural field in in Thrace region of Turkey. Each fungi enriched in malt extract broth media and 1 mL of these enriched media was inoculated into 100 mL of acetochlor solutions that suggested for using application concantrations in agricultural field for farmers (11000 mg L) for sunflower and corn agriculture. Bioremediation results of acetochlor have shown different results according to the types of fungi. Our results indicate that Tolypocladium geodes and Cordyceps cicadae might be used in acetochlor bioremediation with a significant acetochlor, COD, TOC and BOD reduction and can be used for rehabilitation of agricultural fields or receiving environments for removal the opposite effects of acetochlor or other herbicides.
