“…Several bacterial species isolated from the soil showed lower degradation activity regarding parathion, molinate and isoxathion in a medium enriched by nutrients (e.g. glucose) than in a nutrient-poor medium (Imai and Kuwatsuka 1986;Ohshiro et al 1996). The less than 50 % of methomyl-degrading rates for Sphingomonas sp.…”

Complex microbial communities from river biofilms might contain microorganisms capable of degrading xenobiotic pollutants such as pesticides (e.g. methomyl, which is commonly detected in rivers). Therefore, this study was used to determine the methomyl degradation potential of bacteria consortia and single bacterial strains acclimatized and isolated from natural river biofilms to provide biomaterials for bioremediation of water that is contaminated with methomyl. Natural river biofilms were culture enriched with methomyl as the sole carbon source to obtain acclimatized bacterial consortia and single bacterial strains. The microbial consortium on the ceramic discs was able to remove 91 % of added methomyl (50 mg l -1 ) in 7 days. The longer-acclimatized bacterial consortium on loofah sponges removed methomyl more quickly than the shorter-acclimatized consortium, but both had similar removal capabilities (i.e. 92.4 and 92.2 %). This finding suggested that the former might contain more methomyl degraders than the latter. However, after preservation at 25, 4 and -20°C for 1 or 3 months, the methomyl degradation ability of the bacterial consortia decreased significantly, indicating loss of methomyl degraders during preservation. Three bacterial species were isolated from acclimatized river biofilms, and only one species, identified as Sphingomonas sp., was able to remove methomyl, with a 7-day removal rate of 44.7 % when sugar was added and of 32.5 % when no sugar was added. These results suggested that an additional carbon source might slightly improve the ability of Sphingomonas sp. to degrade methomyl. Acclimatized bacterial consortia have a higher potential for treating methomyl-contaminated water than isolated bacterial species.

IAZINON is an organophosphorous insecticide that is ……….commonly used to control various agricultural and household pests and is frequently found as contaminant in water bodies. In the present study, a diazinon degrading bacterium was isolated from agricultural drainage ditches (Fayoum, Egypt) by enrichment technique. Based on morphological, biochemical and 16S rDNA gene sequencing, it was identified as Pseudomonas aeruginosa. A pure culture of P. aeruginosa was grown in minimal medium supplemented with diazinon as sole carbon source. The influence of diazinon concentration, temperature and pH on the bacterial growth and rate of diazinon degradation was investigated. The maximum capability of diazinon degradation (83.6 %) was achieved at concentration 400 ppm of diazinon at pH value 7.0 and temperature 30°C within 14 days. Therefore, P. aeruginosa can be used efficiently for the environmental cleanup of agricultural wastewater contaminated with high levels of diazinon.

“…La especie Pantoea agglomerans, conocida también como Enterobacter agglomerans es una especie que obtuvo un resultado muy signifi cativo en cuanto a la degradación del clorpirifos en relación con la especie Bacillus sp, si bien esta última ha sido encontrada en la gran mayoría de suelos y se ha demostrado su capacidad degradadora de sustancias como los OPs (38)(39)(40), la especie Pantoea agglomerans ha mostrado su capacidad para otro tipo de sustancias como arsénico y derivados del petróleo (37,(41)(42)(43). Este es uno de los primeros trabajos en el que se evidencia la capacidad degradadora de las bacterias anteriormente mencionadas para compuestos de tipo organofosforado, utilizando como base el hecho de que esta clase de microorganismos utiliza enzimas especializadas para degradarlos.…”
