Many studies indicate the favorable effect of biochar on soil quality and plant fitness. A few interactions with rhizosphere bacteria their impact development nutrient acquisition have been reported. In this study, pot experiments in a glasshouse were performed to figure out interactive beneficial Pseudomonas putida TSAU6 amendment wheat (Triticum aestivum L.) growth, uptake, biological activit...

The study evaluated chemical composition, fermentation profile, microbial population and dry matter recovery of silages made from mixtures palisade grass (Urochloa brizantha cv. Marandu) forage peanut (Arachis pintoi Belmonte). experiment was conducted analyzed in a complete randomized factorial design using 5 levels each (0, 25, 50, 75 100% on fresh basis), with without inoculant 3 replication...

Symbiotic nitrogen fi xation has important role in sustainable soybean production because of utilization of atmospheric nitrogen for soybean nutrition. Pre-sowing soybean seed inoculation with selected rhizobial strains is used to improve the amount of symbiotically fi xed nitrogen. Besides strain selection, suitable inoculant formulation is important for the success of inoculant application. T...

OBJECTIVE Four lactic acid bacteria (LAB) strains isolated from common vetch, tall fescue and perennial ryegrass on the Tibetan Plateau were characterized, and their effects on the fermentation quality of Italian ryegrass (Lolium multiflorum Lam.) silage were studied. METHODS The four isolated strains and one commercial inoculant (G, Lactobacillus plantarum MTD-1) were evaluated using the aci...

Microbiol. 38:493-500. Understanding the impact of environmental variables on interstrain competition is important to ensure the successful use of rhizobial inoculant. In eight inoculation trials cond...

Recent advances in silage microbiology are reviewed. Most new techniques in silage microbiology use the polymerase chain reaction (PCR) to make copies of a portion of the DNA in microorganisms. These techniques allow us to identify and quantify species as well as do community analysis. The PCR-based techniques are uncovering new species, both bacteria and fungi, during storage and feeding. Sila...

Rhizobium sullae strain WSM1592 is an aerobic, Gram-negative, non-spore-forming rod that was isolated from an effective nitrogen (N2) fixing root nodule formed on the short-lived perennial legume Hedysarum coronarium (also known as Sulla coronaria or Sulla). WSM1592 was isolated from a nodule recovered from H. coronarium roots located in Ottava, bordering Sassari, Sardinia in 1995. WSM1592 is h...

The reestablishment of autochthonous shrubs species is an essential strategy for recovering degraded soils under semiarid Mediterranean areas. A field experiment was carried out to assess the effectiveness of an immobilized microbial inoculant (Azospirillum brasilense and Pantoea dispersa) and the addition of organic olive residue (alperujo), for plant growth promotion of Cistus albidus L. and ...

The objective of this study is to verify the population density and the dynamics of tillering in the Marandu palisade grass sward subjected to nitrogen (N) fertilization strategies, characterized by the N supply via urea or bacterial inoculant (Azospirillum brasilense). The treatments comprised of four nitrogen fertilization strategies: (A) Without fertilization, (B) 80 kg N/ha, (C) inoculant (...

Mesorhizobium loti strain R7A was isolated in 1993 in Lammermoor, Otago, New Zealand from a Lotus corniculatus root nodule and is a reisolate of the inoculant strain ICMP3153 (NZP2238) used at the site. R7A is an aerobic, Gram-negative, non-spore-forming rod. The symbiotic genes in the strain are carried on a 502-kb integrative and conjugative element known as the symbiosis island or ICEMlSym(R...
