“…The strains are characterized and tested with different concentrations of the pesticide studied. DDT-metabolising microbes have been isolated from a range of habitats, including animal feces, soil, sewage, activated sludge, and marine and freshwater sediments (Johnsen, 1976;Lal & Saxena, 1982;Rochkind-Dubinsky et al, 1987). The degradation of organochlorine pesticides by pure cultures has been proven to occur in situ.…”

“…Besides its high persistence in the environment, lindane also bioaccumulates in fat tissue due to its high solubility in lipids, affecting non-target organisms, also including human beings (Lal and Saxena, 1982;Willet et al, 1998;Zucchini, 2009). Use of lindane is therefore prohibited in many countries and it was listed under the Stockholm Convention on Persistent Organic Pollutants in 2009(UNEP, 2009.…”

“…However, many pesticides are nonspecific in their mode of action, resulting in changes to the composition of non-target microorganisms within the phyllosphere, including those that may have been of benefit to the plant. The effects of a particular pesticide on phyllosphere microbes are dependent upon the specific chemical properties of the pesticide (including any associated emulsifiers or other chemicals if the pesticide is mixed prior to application), the concentration at which the pesticide is used, the types of indigenous phyllosphere microorganisms present, and the environment in which the microorganisms are growing (Lal and Saxena, 1982). The application of pesticides may decrease the microbial biomass due to the direct toxicity of the pesticide (Ko and Lockwood, 1968), or in some cases increase the microbial biomass because of the pesticide (and other associated emulsifiers or solvents) supplying a nutrient source (Chinalia and Killham, 2006), in addition to changes due to indirect ecological effects such as the death of microbial predators, or in some cases there may be no effect at all (Pandey and Chauhan, 2007).…”

Although pesticides have been extensively used for controlling insects and disease pathogens of plants, little is known regarding the impacts of applying these pesticides on the microbial community in the plant phyllosphere. Here, we report the effects of cypermethrin pesticide application upon the microbial community of the pepper plant phyllosphere. Assessments were made using culture-independent techniques including phospholipid fatty acid analysis (PLFA) and 16S rRNA gene directed Polymerase Chain Reaction with Denaturing Gradient Gel Electrophoresis (PCR-DGGE). During the 21 day greenhouse study, PLFA results indicated that both total and bacterial biomass increased after application of the pesticide. PLFA profiles also indicated that Gram-negative bacteria became predominant. DGGE analysis confirmed a significant change in bacterial community structure within the phyllosphere following the pesticide application where different dendrogram clusters were observed between control and treated samples. Phylogenetic analysis also suggested a change in bacterial phyla following treatment, where bands sequenced within control cultures were predominantly of the Firmicutes phylum, but those bands sequenced in the treated samples were predominantly members of the Bacteroidetes and γ-Proteobacteria phyla. In conclusion, this study revealed an increase in bacterial abundance and a shift in community composition within the pepper plant phyllosphere following the pesticide application, and highlighted the effective use of PLFA and PCR-DGGE for studying the effect of pesticides upon indigenous phyllosphere microbes. IntroductionThe indigenous microbial communities that reside within the phyllosphere are highly diverse and include many different species of bacteria, filamentous fungi, yeasts and algae (Lindow and Brandl, 2003). The community composition of phyllosphere microbes are affected by many different factors including plant species, fluctuations in ambient temperature, changes to relative humidity, nutrient availability upon the plant surface and direct solar UV radiation (Lindow and Leveau, 2002). Phyllosphere microbes often have a direct positive influence in altering plant surface properties, where
