(2008)Gibberellins (GAs) are tetracyclic diterpenoid phytohormones that were first identified as secondary metabolites of the fungus Fusarium fujikuroi (teleomorph, Gibberella fujikuroi). GAs were also found in the cassava ...
-
(Springer-Verlag, 1971)Larvae of Pleuroncodes monodon (Milne-Edwards, 1837), a red crab of commercial importance in South America, were reared in the laboratory at 2 different temperatures (15° and 20°C), from hatching up to the last larval ...
-
(2012)Microbiota presumably plays an essential role in inhibiting pathogen colonization and in the maintenance of health in oysters, but limited data exist concerning their different growth phases and conditions. We analyzed the ...
-
(Springer New York, 2009)Dominant bacterial microbiota of the gut of juvenile farmed Atlantic salmon was investigated using a combination of molecular approaches. Bacterial community composition from the stomach, the pyloric caeca, and the intestine ...
-
(2009)Epidemics of Vibrio parahaemolyticus in Chile have occurred since 1998. Direct genome restriction enzyme analysis (DGREA) using conventional gel electrophoresis permitted discrimination of different V. parahaemolyticus ...
-
(Blackwell Publishing Ltd, 2009)It is well known that nonlinear electrostatic instabilities can be triggered in a plasma with streaming ion species in the presence of finite-amplitude Alfvén cyclotron waves. The instability occurs when the phase velocity ...
-
(Blackwell Publishing Ltd, 2007)The effects of a finite-amplitude Alfvén wave in a plasma system with a proton and an alpha-particle beam, are studied. The system is described by a fourteenth-order polynomial providing, thereby, many decay channels for ...

Partial removal of lipopolysaccharide from Thiobacillus ferrooxidans affects its adhesion to solids (1994)Conditions for the partial removal of lipopolysaccharide (LPS) from Thiobacillus ferrooxidans are described. Raising the pH of the solution containing the cells from pH 1.5 to pH 6.8 to 8.0 releases about 50% of the LPS ...
-
(Oxford University Press, 1997)Exclusion experiments on global UV (A and B) radiation and global UVB were performed in 460 1 mesocosms with plankton communities from the oligotrophic Andean lake Laguna Negra (33°35'S-70°04'W; 2700 m a.s.1.). The ...
-
(1988)Two members of the genus Thermus were examined for their resistance to toxic inorganic compounds. They both proved to be fairly resistant to tellurite and selenite and to many other heavy metal salts. Cell extracts of ...
-
(2005)Nine biological species, or mating populations (MPs), denoted by letters A to I, and at least 29 anamorphic Fusarium species have been identified within the Gibberella fujikuroi species complex. Members of this species ...
-
(2002)Inorganic polyphosphate (polyP) polymers are widely distributed in all kinds of organisms. Although the presence of polyP in members of the domain Archaea has been described, at present nothing is known about the enzymology ...
