Arbuscular mycorrhizal fungi in the Jatropha curcas rhizosphere
Jatropha curcas L. is a Euphorbiaceae characterized as drought tolerant, with low nutrient exigency and resistant to pests and diseases; furthermore, its seeds have a high content of good quality oil, which makes it a potential plant species for biodiesel production. The association of J. curcas with arbuscular mycorrhizal fungi (AMF) may enhance some of these promising features. The aim of this work was to assess AMF...

The role of phenolic compounds in the defense of sooty mold of olive leaves (Olea europea L.)
The aim of this study is to demonstrate the role of phenolic compounds in the olive leaves infected by sooty mold. The results show that the presence of sooty mold induces a high production of polyphenols in infected leaves of olive compared to the uninfected ones. The high concentrations of flavonoids and alkaloids in the infected trees suggest that they make the olive tree resistant to this fungi disease. Analyses by...

Reduced intracellular drug accumulation augments fluoroquinolone and β-lactam drugs resistance in clinical Gram negative bacteria from Nigeria
In Nigeria, quinolones and β-lactam antibiotics are widely used as broad-spectrum antibiotics to treat infections caused by various Gram-negative pathogens. The outer membrane is the major permeability barrier limiting target access to quinolones and other drugs in Gram-negative bacteria. This study aimed to identify the role of outer membrane porins (OMPs) and uptake in fluoroquinolone (FQ) and β-lactam drugs...

Variability in Fusarium oxysporum f.sp. ciceris causing wilt in chickpea
Fusarium wilt caused by Fusarium oxysporum f.sp. ciceris (Padwick) Matuo and K. Sato is a major constraint in successful cultivation of chickpea. Therefore, in the present study, 24 isolates of F. oxysporum f.sp. ciceris collected from different chickpea growing areas of Punjab and adjoining states were assessed for morphological variations. Among 24 isolates, the maximum (8.78 mm/days) and minimum (5.00 mm/day) growth...

Exploiting novel rhizosphere Bacillus species to suppress the root rot and wilt pathogens of chickpea
Thirty isolates of Bacillus were collected from chickpea rhizosphere and screened for their in vitro inhibition against root rot (Rhizoctonia bataticola) and wilt (Fusarium oxysporum f.sp. ciceri) pathogens and growth promotion of chickpea. Based on the in vitro inhibition and growth promotion tests, the best eight isolates were selected and PCR-based detection of antibiotics genes viz., surfactin, iturin, fengycin and...

Different dosages of SALMEX® to control Clostridium perfringens in poultry feed ingredients
Ingredients of animal origin are important for the animal feed industry because they contain significant amounts of nutrients, minerals, and vitamins. However, the use of these raw materials is a problem due to pathogenic bacterial contamination, especially Clostridium perfringens and Salmonella spp. One way to control contamination is the addition of chemical products during ingredient production. Thus, the objective...

Bacterial inoculation effect on soil biological properties, growth, grain yield, total phenolic and flavonoids contents of common buckwheat (Fagopyrum esculentum Moench) under hilly ecosystems of North-East India
Field experiments were carried out at Research Farm, ICAR Sikkim Centre, Tadong during two consecutive Rabi seasons of 2012 and 2013 to determine the effect of different microbial inoculants on selected soil biological properties, growth, yield, and quality of common buckwheat, and then identify the best inoculant for application for local common buckwheat production in hilly ecosystem of North-East India. The results...
