“…The two atrazine addition levels were selected according to the range of contamination levels in soil (0.017 mg kg À1 -482.7 mg kg À1 ) reported by Grigg et al (1997) as well as its limited phyto-availability because only the roots penetrating through the mesh would be exposed to atrazine in the side-arm compartment. Four replicate pots of each treatment were set up.…”

a b s t r a c tThe effects of an arbuscular mycorrhizal (AM) fungus (Glomus etunicatum) on atrazine dissipation, soil phosphatase and dehydrogenase activities and soil microbial community structure were investigated. A compartmented side-arm ('cross-pot') system was used for plant cultivation. Maize was cultivated in the main root compartment and atrazine-contaminated soil was added to the side-arms and between them 650 or 37 mm nylon mesh was inserted which allowed mycorrhizal roots or extraradical mycelium to access atrazine in soil in the side-arms. Mycorrhizal roots and extraradical mycelium increased the degradation of atrazine in soil and modified the soil enzyme activities and total soil phospholipid fatty acids (PLFAs). Atrazine declined more and there was greater stimulation of phosphatase and dehydrogenase activities and total PLFAs in soil in the extraradical mycelium compartment than in the mycorrhizal root compartment when the atrazine addition rate to soil was 5.0 mg kg À1 . Mycelium had a more important influence than mycorrhizal roots on atrazine degradation. However, when the atrazine addition rate was 50.0 mg kg À1 , atrazine declined more in the mycorrhizal root compartment than in the extraradical mycelium compartment, perhaps due to inhibition of bacterial activity and higher toxicity to AM mycelium by atrazine at higher concentration. Soil PLFA profiles indicated that the AM fungus exerted a pronounced effect on soil microbial community structure.

“…Therefore, it is necessary to investigate the effects of various environmental factors on the growth ability of the tested microorganisms (Pattanasupong et al, 2004). On the other hand, it was found that various materials were used as soil amendments, nutrients, to increase and enhance the degradation potential of xenobiotics such as Yard manure compost (Guo et al, 1991;Cole et al, 1995;Gan et al, 1996;Zheng and Cooper, 1996;Vogel, 1996;Grigg et al, 1997;Leoni et al, 1997), biogas slurry and compost (Kadian et al, 2008;Belal et al, 2008). However, after remediation toxicity assessments are needed.…”

One strain of microorganisms was isolated from soil previously treated with pendimethalin using enrichment technique and identified using 16S rDNA as Pseudomonas putida (E15). The effect of pH and temperature on the growth ability of the tested strain was investigated. The results show that the optimum pH and temperature for the growth of pendimethalin dissipating strain were 7 and 30°C, respectively. P. putida was used to dissipate pendimethalin from mineral liquid medium with half-live of 5.46 days. Pendimethalin half-live was 51.9 days in untreated mineral liquid medium. P. putida and compost were also evaluated for detoxification of pendimethalin in clay soil. P. putida and compost were effective in pendimethalin dissipation in soil with half-live of 4.67 and 5 days, respectively. Pendimethalin half-live was 62.43 days in untreated soil. Pendimethalin treatment affected analysis of the microbial population growing in P. putida or compost treating soil leachates showed an overall increase in the population of microorganisms. There is no toxicity of pendimethalin detected in soil on cucumber plants after treatment with P. putida or compost. Pendimethalin significantly decreased germination and increased cucumber seedlings mortality rate. P. putida and compost treatments increased the growth parameters. Moreover, no significant difference was observed in the most growth parameters between P. putida and compost treatments. Abnormal development of xylem tissue was observed in pendimethalin contaminated soil as a result of phytotoxicity. The results suggest that bioremediation by P. putida and compost was considered to be effective method for detoxification of pendimethalin in soil.

“…This is important since, to date, pure strains able to mineralize a pesticide have been reported only for a few pesticide compounds. Moreover, bioaugmentation using lab‐cultured pollutant‐degrading isolates often had limited success (Chatterjee et al , 1982; Grigg et al , 1997; Struthers et al , 1998; Topp, 2001; Mertens et al , 2006; Moran et al , 2006; Singh et al , 2006; Bazot & Lebeau, 2008). On the other hand, the few reports on bioaugmentation of contaminated matrices with pollutant‐primed materials showed promising results (Barbeau et al , 1997; Runes et al , 2001; Grundmann et al , 2007).…”

Microcosms were used to examine whether pesticide-primed soils could be preferentially used over nonprimed soils for bioaugmentation of on-farm biopurification systems (BPS) to improve pesticide mineralization. Microcosms containing a mixture of peat, straw and either linuron-primed soil or nonprimed soil were irrigated with clean or linuron-contaminated water. The lag time of linuron mineralization, recorded for microcosm samples, was indicative of the dynamics of the linuron-mineralizing biomass in the system. Bioaugmentation with linuron-primed soil immediately resulted in the establishment of a linuron-mineralizing capacity, which increased in size when fed with the pesticide. Also, microcosms containing nonprimed soil developed a linuron-mineralizing population, but after extended linuron feeding. Additional experiments showed that linuron-mineralization only developed with some nonprimed soils. Concomitant with the increase in linuron degradation capacity, targeted PCR-denaturing gradient gel electrophoresis showed the proliferation of a Variovorax phylotype related to the linuron-degrading Variovorax sp. SRS16 in microcosms containing linuron-primed soil, suggesting the involvement of Variovorax in linuron degradation. The correlation between the appearance of specific Variovorax phylotypes and linuron mineralization capacity was less clear in microcosms containing nonprimed soil. The data indicate that supplementation of pesticide-primed soil results in the establishment of pesticide-mineralizing populations in a BPS matrix with more certainty and more rapidly than the addition of nonprimed soil.
