A Light Microscopical Investigation And
113 randomly selected frustules of Cyclotella taxa, taken from the plankton of four lakes, have been investigated with respect to variation between the two thecae of each frustule and also variation within and between populations occorring in the different lakes. Multivariate statistical analyses of phenetic similarity of the 226 thecae were based on a data matrix recording the status of 11 cha...
متن کاملElectron microscopical investigation of asbestos fibers
Examination of asbestos fibers by electron microscopical techniques enables the observer to distinguish among the fiber types by morphological and structural characteristics. Chrysotile asbestos fibers are composed of bundles of fibrils. Fibers are often curvilinear with splayed ends. Individual fibrils consist of a central capillary defined by an electron dense crystalline wall. With increasin...
متن کاملCloning of poly (3-Hydroxybutyrate) synthesis genes from Azotobacter vinelandii into Escherichia coli
The Azotobacter vinelandii is an aerobic, nitrogen-fixing bacterium with the ability to accumulate polyesters such as poly (3-hydroxybutyrate), a particular group of the polyhydroxyalkanoates (pha), when will be cultivated on several carbon sources, including sucrose. Although the capacity of Azotobacter strains to accumulate polyesters is well known, and the genes responsible for their synthes...
متن کاملLocalization of poly(3-hydroxybutyrate) (PHB) granule-associated proteins during PHB granule formation and identification of two new phasins, PhaP6 and PhaP7, in Ralstonia eutropha H16.
Poly(3-hydroxybutyrate) (PHB) granules are covered by a surface layer consisting of mainly phasins and other PHB granule-associated proteins (PGAPs). Phasins are small amphiphilic proteins that determine the number and size of accumulated PHB granules. Five phasin proteins (PhaP1 to PhaP5) are known for Ralstonia eutropha. In this study, we identified three additional potential phasin genes (H1...
متن کاملThe GacS sensor kinase regulates alginate and poly-beta-hydroxybutyrate production in Azotobacter vinelandii.
Azotobacter vinelandii produces two polymers: the extracellular polysaccharide alginate and the intracellular polyester poly-beta-hydroxybutyrate (PHB). A cosmid clone (pSMU588) from an A. vinelandii gene library diminished alginate production by A. vinelandii mucoid strain ATCC 9046. The nucleotide sequence and predicted amino acid sequence of the locus responsible for the mucoidy suppression ...
