Auxin, one of the most important phytohormones enhances the root architecture, nutrient acquisition and plant growth. Present study provides the screening, characterization and optimization of auxin producing bacteria from wheat rhizosphere. Effects of auxin producing isolates on seed germination and growth of T. aestivum were also evaluated. The Bacillus megaterium, Escherichia coli, Klebsiell...

In this review it is hoped to trace the evolution of our concepts of the absorption of digestion products of dietary protein. Many of the ideas current today were readily accepted by the end of the last century but were ignored by orthodox physiologists during the first half of this century-concepts of sugar absorption suffered a similar fate. Although it has now become clear that brush border ...

A novel anamorphic species of yeast belonging to the genus Candida was isolated from tar in Canada. Morphological and physiological observations, as well as phylogenetic analyses, were performed. Conidiophores were produced, were usually short and had sympodial growth, numerous bud scars and a rachis-like structure. They bore one or more conidia. Pseudomycelium was scarcely produced and true my...

Burkholderia glumae is the primary causal agent of bacterial panicle blight of rice. In this study, 11 naturally avirulent and nine virulent strains of B. glumae native to the southern United States were characterized in terms of virulence in rice and onion, toxofalvin production, antifungal activity, pigmentation and genomic structure. Virulence of B. glumae strains on rice panicles was highly...

the objective of this study was to produce fish peptone from tuna (thunnus tonggol) viscera, by alcalase. response surface methodology (rsm) was employed for optimizing the temperature and ph. hydrolysis was done in different tempratures (50-65˚c) , ph (8-8. 5) and selected 13 treatments. samples with higher value of protein were used instead of the standard peptones which applied in commercial...

BACKGROUND Fresh sprouted seeds have been associated with a number of large outbreaks caused by Salmonella and Shiga toxin-producing E. coli. However, the high number of commensal bacteria found on sprouted seeds hampers the detection of these pathogens. Knowledge about the composition of the sprout microbiome is limited. In this study, the microbiome of mungo bean sprouts and the impact of buf...

The Leptothrix species, Fe-oxidizing bacteria, produce an extracellular, microtubular sheath with a complicated organic–inorganic hybrid nature. We have discovered diverse industrial functions for this material, e.g., electrode material for Li-ion batteries, catalyst enhancers, pigments, plant growth promoters, and plant protectants. To consistently obtain material with the qualitative and quan...

We report here the first analysis of chitinase regulation in Moniliophthora perniciosa, the causal agent of the witches' broom disease of cacao. A multivariate statistical approach was employed to evaluate the effect of several variables, including carbon and nitrogen sources and cultivation time, on M. perniciosa non-secreted (detected in mycelium, i.e. in symplasm and cell wall) and secreted ...

Renanthera imschootiana Rolfe is an endangered tropical epiphytic orchid that is threatened with extinction due to over-collection and the loss of suitable habitats. In vitro propagation is a useful way to mass produce plants for re-establishment in the wild and for commercial propagation. Seeds collected 150 days after pollination (DAP) were the optimum stage for in vitro culture. Seed germina...
