A new endosulfan-degrading fungus, Mortierella species, isolated from a soil contaminated with organochlorine pesticides

A new endosulfan-degrading fungus, Mortierella species, isolated from a soil contaminated with organochlorine pesticides

Endosulfan is a broad-spectrum cyclodiene insecticide that has been used extensively for over 30 years on a variety of crops. It is a mixture of two stereoisomers, a and b endosulfan, in a ratio of 7 : 3. Its toxicity is extremely high against fish and aquatic invertebrates, and it has increasingly been implicated in mammalian gonadal toxicity, genotoxicity and neurotoxicity; however, endosulfa...

Arthrobacter nitrophenolicus sp. nov. a new 2-chloro-4-nitrophenol degrading bacterium isolated from contaminated soil

Strain SJConT, a 2-chloro-4-nitrophenol (2C4NP) degrading bacterium, was isolated from soil collected from a pesticide-contaminated site in Punjab, India. The strain, which stained Gram positive, displayed a rod-coccus life cycle, and possessed a type A3α peptidoglycan (L-Lys-L-Ala3), MK-9(H2) as the major menaquinone, anteiso-C15 and iso-C15:0 as the major cellular fatty acids, and diphosphati...

Characterization of Bacteria Degrading Petroleum Derivatives Isolated from Contaminated Soil and Water

Three New Records of Mortierella Species Isolated from Crop Field Soil in Korea

Three new fungal species of the genus Mortierella, Mortierella zychae, Mortierella ambigua, and Mortierella indohii, have been reported in Korea. The fungi were encountered during a study on the fungal community of soil samples collected from different locations in Korea. The species were identified based on molecular and morphological analyses. This study presents detailed descriptions of the ...

Study of lipase production by a filamentous fungus isolated from soil contaminated with lipid residues

Lipases are the special kind of esterases belong to subclass 1 of hydrolytic enzyme class 3 and have been assigned subsub class 3.1.1 due to their specificity for carboxylic acid ester bonds. The biological function of lipase is to catalyze the hydrolysis of triacylglycerols to give free fatty acid, diacylglycerols, mono-acylglycerols and glycerol. They constitute the most important group of bi...
