The legume nodules are a rich source not only of rhizobia but also endophytic bacteria exhibiting plant growth-promoting mechanisms with potential as biostimulants. In this work we analyzed the genomes Phyllobacterium endophyticum PEPV15 and Rhizobium laguerreae PEPV16 strains, both isolated from Phaseolus vulgaris nodules. silico analysis showed that these two strains contain genes related to ...

The microalgae–bacteria consortium is a promising and sustainable alternative for industrial wastewater treatment, since it may allow good removal of organic matter nutrients, as well the possibility producing products with added value from algae biomass. This research investigated best bacterial microalgae inoculation ratio system start-up evaluation removing (as chemical oxygen demand (COD)),...

یکی از روش های نوین حذف بیولوژیکی نیتروژن، فرایند نیتریفیکاسیون و دنیتریفیکاسیون همزمان (snd) است. انجام این فرایند در راکتورهای بیوفیلمی مزایایی نظیر هزینه پایین و راندمان بالا دارد. در این تحقیق حذف n-nh_4^+، cod،no_3^--n، tn (نیتروژن کل) و رشد بیومس معلق طی فرایند snd در راکتور mbbr (moving bed biofilm reactor) با انجام مدلسازی ریاضی مورد مطالعه قرار گرفت. در این مدل انتقال جرم اکسیژن از فاز...

The oceanic dissolved organic phosphorus (DOP) pool is mainly composed of P-esters and, to a lesser extent, equally abundant phosphonate and P-anhydride molecules. In phosphate-limited ocean regions, diazotrophs are thought rely on DOP compounds as an alternative source (P). While both phosphonates effectively promote dinitrogen (N 2 ) fixation, the role P-anhydrides for unknown. Here we explor...

Close to redox boundaries, dark carbon fixation by chemoautotrophic bacteria may be a large contributor to overall carbon fixation. Still, little is known about the relative importance of this process in lake systems, in spite the potentially high chemoautotrophic potential of lake sediments. We compared rates of dark carbon fixation, bacterial production and oxygen consumption in sediments fro...

The implementation of beneficial microorganisms for plant protection has a long history. Many rhizobia bacteria are able to influence the immune system of host plants by inducing resistance towards pathogenic microorganisms. In this report, we present a translational approach in which we demonstrate the resistance-inducing effect of Ensifer meliloti (Sinorhizobium meliloti) on crop plants that ...

Increasing nitrogen (N) deposition profoundly affects nutrient cycling in soil, thereby influencing forest ecosystem productivity and function. Soil microorganisms are integral driving turnover; the changes microbial communities response to N associated soil availability, especially of limited nutrients, far from clear. To explore bacterial fungal their key environmental drivers under depositio...

The potential coupling of nitrogen (N2) fixation and sulfate reduction (SR) was explored in sediments of the Peruvian oxygen minimum zone (OMZ). Sediment samples were retrieved by a multiple corer at six stations along a depth transect (70–1025 m water depth) at 12 S, covering anoxic and hypoxic bottom water conditions. Benthic N2 fixation, determined by the acetylene reduction assay, was detec...

Sugarcane is a globally important food, biofuel and biomaterials crop. High nitrogen (N) fertilizer rates aimed at increasing yield often result in environmental damage because of excess and inefficient application. Inoculation with diazotrophic bacteria is an attractive option for reducing N fertilizer needs. However, the efficacy of bacterial inoculants is variable, and their effective formul...
