There is currently a great deal of information available about the toxic effects oxyfluorfen on soil biochemical activity and microbial biodiversity. However, there no how this herbicide affects plant growth promoting bacteria (PGPB) or their properties, such as biofilm formation, nitrogen fixation, siderophore auxin production, phosphate solubilisation. As in study an agricultural was polluted...

Soil is a habitat where plant roots and microorganisms interact. In the region of the Brazilian Iron Quadrangle (IQ), studies involving the interaction between microbiota and plants have been neglected. Even more neglected are the studies involving the holoparasite plant Langsdorffia hypogaea Mart. (Balanophoraceae). The geomorphological peculiarities of IQ soil, rich in iron ore, as well as th...

An acid phosphatase activity was detected in the supernatant of Haemophilus parasuis, a Gram-negative pleomorphic bacillus and the causative agent of Glässer's disease in pigs. To identify the gene responsible for the secreted activity, a genomic library of H. parasuis strain ER-6P was produced in Escherichia coli. Screening of the library allowed identification of two homologs to known phospha...

Plant-microbe interactions in the rhizosphere are the determinants of plant health, productivity and soil fertility. Plant growth-promoting bacteria (PGPB) are bacteria that can enhance plant growth and protect plants from disease and abiotic stresses through a wide variety of mechanisms; those that establish close associations with plants, such as the endophytes, could be more successful in pl...

Four strains of plant growth-promoting bacteria (PGPB), including three strains of Azospirillum and Pseudomonas fluorescens 313 were used to inoculate seeds of wheat, tomato, pepper, and cotton. Inoculated seedlings were grown to the two or three-leaf stage. After harvest, seven different environmental and technical conditions were evaluated to determine the effect of these conditions on the re...

The overuse of agricultural chemicals such as fertilizer and pesticides aimed at increasing crop yield results in environmental damage, particularly in the Sahelian zone where soils are fragile. Crop inoculation with beneficial soil microbes appears as a good alternative for reducing agricultural chemical needs, especially for small farmers. This, however, requires selecting optimal combination...

The key to achieving successful, reproducible results following the introduction of beneficial microbes into soil relies on the survival rate of the inoculated bacteria in a heterogeneous soil environment and hence an improved encapsulation method was developed. Owing to the constraints associated with the inoculum formulation, in this study, encapsulation of a plant growth promoting bacteria (...

The use of microorganisms to improve the availability of nutrients to plants is of great importance to agriculture. This study aimed to evaluate the effect of triple inoculation of cowpea with arbuscular mycorrhizal fungi (AMF), plant growth-promoting bacteria (PGPB) and rhizobia to maximize biological nitrogen fixation (BNF) and promote plant growth. The experiment was conducted in a greenhous...

Soil salinization, one of the most common causes soil degradation, negatively affects plant growth, reproduction, and yield in plants. Saline conditions elicit some physiological changes to cope with imposed osmotic oxidative stresses. Inoculation plants bacterial species that stimulate their i.e., growth-promoting bacteria (PGPB), may help counteract saline stress, thus improving plant’s fitne...
