Conjugation by mosquito pathogenic strains of Bacillus sphaericus.
A mosquito pathogenic strain of Bacillus sphaericus carried out the conjugal transfer of plasmid pAM beta 1 to other strains of its own and two other serotypes. However, it was unable to conjugate with mosquito pathogens from three other serotypes, with B. sphaericus of other DNA homology groups or with three other species of Bacillus. Conjugation frequency was highest with a strain having an a...
متن کاملDistribution of Alginate Lyase Activity among Strains of Bacillus circulans.
Strains from four different DNA relatedness groups of Bacillus circulans showed apparent alginate lyase activity; the activity of three strains examined had mannuronidase specificity. A representative strain of group 4 also produced apparent inducible unsulfated chrondroitin lyase activity.
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 اولGenetic Variability among Strains of the Entomopathogenic Nematode Steinernema feltiae.
A systematic program of genetic improvement was initiated by assessing the phenotypic variation of Steinernema feltiae strains for two traits assumed to limit efficacy: ultraviolet tolerance and host-finding ability. All of the strains assayed showed both low ultraviolet tolerance and poor host-finding ability, indicating that the likelihood of improving these traits through more extensive popu...
متن کاملPhylogenetic analysis of Bacillus sphaericus and development of an oligonucleotide probe specific for mosquito-pathogenic strains.
The 16S rRNA gene sequences for six strains of Bacillus sphaericus representing five distinct DNA homology groups and one strain of Bacillus fusiformis have been determined. An-oligonucleotide probe based on the area approximately between position 186 and 198 (Escherichia coli numbering) of the 16S rRNA gene of the mosquito pathogen, strain 2362, hybridised to DNA from strains of DNA homology g...
