15 صفحه اولHumic and fulvic acids stimulate the growth of Mycobacterium avium.
Mycobacterium avium, an environmental, opportunistic pathogenic mycobacterium, has been isolated frequently and in high numbers from waters in Finland and from acid, brown water swamps of the southeastern coastal USA. M. avium has also been recovered in high numbers from Finnish drinking water and frequently isolated from Finnish AIDS patients. Boreal forests and brown water swamps are similar ...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
15 صفحه اولPolyacrylamide Gel Electrophoresis of Humic and Fulvic Acids after Acid Hydrolysis
Two soil humic acids (HA), a marine sediment HA, and a soil fulvic acid (FA), were fractionated by polyacrylamide gel electrophoresis in the presence of denaturing agents before and after 6N HCl hydrolysis. After acid hydrolysis, the intensity of the high molecular size (MS) fraction decreased considerably in all HAs. On the other hand, a new high-MS fraction appeared in the FA after hydrolysis...
