“…Microbial reduction of Cr(VI) to less toxic and less mobile Cr(III) is considered an effective method for remediation of Cr(VI)-contaminated soil (Kanmani et al 2012 ). Certain microorganisms have been reported to reduce Cr(VI) in soil, such as strains of Pseudomonas (Oves et al 2013 ), Microbacterium (Soni et al 2014 ), Brucella (Maqbool et al 2015 ), Bacillus (He et al 2010 ; Kathiravan et al 2011 ; Kumari et al 2014 ), Streptomyces (Polti et al 2009 ; Aparicio et al 2015 ), Staphylococcus (Zhang et al 2014 ) and Pannonibacter phragmitetus (Chai et al 2009 ; Liao et al 2014 ; Wang et al 2015 ). However, most of the studies on bioreduction of Cr(VI) were performed with direct addition of pure cultures to soil, which is inconvenient for transportation and storage.…”

Lysinibacillus fusiformis ZC1 is an efficient Cr(VI)-reducing bacterium that can transform the toxic and soluble chromate [Cr(VI)] form to the less toxic and precipitated chromite form [Cr(III)]. As such, this strain might be applicable for bioremediation of Cr(VI) in soil by reducing its bioavailability. The study objective was to prepare a microcapsule agent of strain ZC1 for bioremediation of Cr(VI)-contaminated soil. Using a single-factor orthogonal array design, the optimal fermentation medium was obtained and consisted of 6 g/L corn flour, 12 g/L soybean flour, 8 g/L NH4Cl and 6 g/L CaCl2. After enlarged fermentation, the cell and spore densities were 5.9 × 109 and 1.7 × 108 cfu/mL, respectively. The fermentation products were collected and embedded with 1 % gum arabic and 1 % sorbitol as the microcapsule carriers and were subsequently spray-dried. Strain ZC1 exhibited viable cell counts of (3.6 ± 0.44) × 1010 cfu/g dw after 50-day storage at room temperature. In simulated soil bioremediation experiments, 67 % of Cr(VI) was reduced in 5 days with the inoculation of this microcapsule agent, and the Cr(VI) concentration was below the soil Cr(VI) standard level. The results demonstrated that the microcapsule agent of strain ZC1 is efficient for bioremediation of Cr(VI)-contaminated soil.

“…Thus, Cr(VI) (25 mg L −1 ) and lindane (250 μg L −1 ) were mixed to evaluate their combined effect on the actinobacteria Streptomyces M7, cultured on artificially contaminated liquid medium. Previous studies have already demonstrated that this strain was tolerant to both contaminants in solid medium and soil . However, its performance in a liquid system where contaminants are highly available has never been evaluated.…”

“…Currently, members of the phylum Actinobacteria are being studied because of their ability to bioremediate co‐polluted soils. In particular, Streptomyces strains are able to bioremediate Cr(VI) and lindane from non‐sterilized co‐contaminated soils . In turn, lindane‐degrading Streptomyces strains were shown to be able to remove lindane in the presence of maize plants and its REs .…”

Environmental mixed pollution by both organic and inorganic compounds are detected worldwide. Phytoremediation techniques have been proposed as ecofriendly methods for cleaning up polluted sites. Several studies have demonstrated enhanced dissipation of contaminants at the root-soil interface through an increase in microbial activity caused by the release of plant root exudates (REs). The aim of this study was to evaluate the effectiveness for Cr(VI) and lindane removal by Streptomyces M7 cultured in a co-contaminated system in presence of maize REs. Our results showed when REs were added to the contaminated minimal medium (MM) as the only carbon source, microbial removal of Cr(VI) and lindane increased significantly in comparison to contaminant removal obtained in MM with glucose 1 g L . The maximum removal of 91% of lindane and 49.5% of Cr(VI) were obtained in the co-contaminated system. Moreover, Streptomyces M7 showed plant growth promoting traits which could improve plant performance in contaminated soils. The results presented in this study provide evidence that maize REs improved growth of Streptomyces M7 when REs were used as a carbon source in comparison to glucose. Consequently, lindane and Cr(VI) removal was considerably enhanced making evident the phytoremediation potential of the actinobacteria-plant partnership.

P ESTICIDES play an important role in preventing insect pests and weeds in crops. However, excessive use of pesticides has been known to be unsafe, due to their toxicity to non-target organisms and the ecosystem. Biodegradation is an innovative approach for decontaminating pesticide pollution. However, compared with the list of extensively used pesticides there are few well-characterized strains of microbes that transform pesticides into less-toxic or more labile products at environmentally useful rates. Fortunately, the technology required to isolate and characterize such microbial strains has improved immensely in the recent years. Furthermore, recent experimental developments have made practical the modification of potentially beneficial biodegradation genes so that they may be optimally expressed in a wide range of microbial species. This reviews article explore the recent studies that have focused on biodegradation of pesticide residues, the mechanism of microbial degradation of pesticides, the factors that affect the degradation of pesticides and the new application of microbial degradation of pesticides.
