Eukaryotic algae represent a highly heterogeneous group in terms of organization, lifestyle, and metabolic capabilities. Unicellular green microalgae are capable biohydrogen production through direct indirect photolysis as well dark fermentation. Most hydrogen studies focus on axenic algal cultures, although these difficult expensive to maintain for continuous operation. Moreover, the complex i...

Three bacterial strains; Pseudomonas sp. TRMK1, Stenotrophomonas sp. TRMK2 and Xanthomonas sp. TRMK3 were isolated from agro-industrial waste by enrichment culture technique that are capable of utilizing phenolic acids as sole source of carbon and energy. These strains were found to utilize p-coumaric, ferulic and caffeic acid. The individual strains utilized 5 mM of mixed phenolic acids within...

Bacillus sp. PS3 produces a glycosylated flagellin. In this study, a number of the glycosylated residues of the flagellin protein were found to be located in the central variable region of this protein. We also report that the motility defect of the Bacillus subtilis flagellin mutant was complemented by Bacillus sp. PS3 flagellin variants without glycosylation, which contained amino acid substi...

In the present study we examined the performance of a thermoalkalophilic bacterial consortium, where the predominant strain was Bacillus sp. SF, in the degradation of Reactive Black 5 (RB5). We used a reactor working in continuous mode and investigated the effects of pH, hydraulic retention time (HRT) and several added salts on colour and chemical oxygen demand (COD) reductions. For the chosen ...

Bioaccumulation of Cd(2+) in soil bacteria might represent an important route of metal transfer to associated mycorrhizal fungi and plants and may have potential as a tool to accelerate Cd(2+) extraction in the bioremediation of contaminated soils. The present study examined the bioaccumulation of Cd(2+) in 15 bacterial strains representing three phyla (Firmicutes, Proteobacteria, and Bacteroid...

The search for cultivation practices that provide productive, social and environmental benefits to the agroecosystem is of great importance sustainable intensification agriculture. objective this study was determine effect multifunctional microorganisms (MM) mix cover crops on gas exchange, production components grain yield soybean. In field experiment, conducted by two growing seasons, experim...

Para la caracterización microbiológica y molecular se aislaron e identificaron microorganismos cultivables de 4 bioinsumos comerciales provenientes del occidente norte Nicaragua. Esto involucró tipificación morfológica a través de: tinción Gram para bacterias observación esporas hongos filamentosos. Se realizó extracción secuenciación ADN (gen ADNr 16S – bacterias, región ITS1- ITS4 filamentoso...

Biological wastewater treatment is economically feasible and ecofriendly. This study was aimed at isolating bacteria from brewery wastes and evaluating their bioremediation potential as individual isolate and/or their consortium in reducing the pollutants of brewery effluents. A total of 40 bacterial isolates were recovered and of these the three best isolates were selected. The selected bacter...

AIMS The aim of this study was to investigate the role of proteases in Bacillus spp. of rhizobacteria in suppressing nematode populations and to understand their mechanism of action. METHODS AND RESULTS Rhizobacteria with nematicidal activity were isolated from soil samples of five root knot nematode-infested farms. Among these strains, nematotoxicities of Bacillus strains were intensively an...
