Metabolism of cobalamins by a soil microorganism.
The occurrence in soil of a large group of bacteria which require vitamin B12 has been reported by Lochhead and Thexton (1952). Thirty cultures obtained from 534 isolates showed dependence upon vitamin B12 for growth. Lochhead and Burton (1954) grouped these 30 cultures into 10 types, based on morphological and physiological characteristics. A study of the nature of the vitamin B12 requirements...
متن کاملMetabolism of alloxanic acid in a soil microorganism.
Alloxan is a polyoxy-pyrimidine of unusual biological interest, being the agent of choice for producing experimental diabetes (Shaw-Dunn, Sheehan, and McLetchie, 1943). Despite the fact that it has been used extensively for many years, very little is known of its ultimate fate in mammals or other forms of life. It is exceedingly unstable at physiological pH values and is spontaneously converted...
متن کاملBiotransformation of Artemisinin by using a Novel Soil Isolated Microorganism
Artemisinin is a potential antimalarial drug effective against the multidrug resistant forms of Malarial Parasites. The current production of artemisinin is insufficient to meet the global demand. In the present study microbial biotransformation of arteannuin B, a biogenetic precursor of artemisinin to the later has been investigated. Screening studies carried out on several soil borne microorg...
متن کاملBiodegradation of imidacloprid by an isolated soil microorganism.
Imidacloprid (1-[(6-chloro-3-pyridinyl)-methyl]-N-nitro-2-imidazolidinimine), a chloronicotinyl insecticide used to control biting and sucking insects, is very persistent in the soil with a half-life often greater than 100 days. Although a few soil metabolites have been reported in the literature, there are no reports of imidacloprid-degrading soil microorganisms. Our objectives were to discove...
متن کاملSoil carbon controlled by plant, microorganism and mineralogy interactions
Rhizosphere, a thin area of soil surrounding roots receiving carbon (C) exudation from plants, represents a site of intense competition for available C and nutrient between surface-reactive particles and soil microorganisms. This competition can reduce the amount of available C to a critical level, it becomes limiting for microbial growth and soil organic matter decomposition. On the other hand...
