Abstract

Adsorption of phenylurea derivatives and chlorosubstituted anilines by Pseudomonas and Aspergillus was studied. All these substances were adsorbed by the microorganisms in large quantities. The bacteria adsorbed more of these substances per biomass unit than the fungi. Adsorption of herbicides by the microorganisms is a physical process and is characterized by the same correlation as adsorption of herbicides by soil. Derivatives of phenylurea and chlorosubstituted anilines are easily washed from the cells with water. Conditions under which the substances were completely desorbed have been studied. Acetylation of 3,4-dichloroaniline by Pseudomonas aurantiaca results in desorption of 3,4-dichloroaniline from the cells of Pseudomonas boreopolis.

Aspergillosis (ASM)

Aspergillosis is the name given to a wide variety of diseases caused by infection by fungi of the genus Aspergillus. Aspergillosis occurs in chronic or acute forms which are clinically very distinct. Most cases of acute aspergillosis occur in patients with severely compromised immune systems. Chronic colonization or infection can cause complications in people with underlying respiratory illnesses. Discover the latest research on aspergillosis here.
