Effects of growth-promoting endophytic Methylobacterium on development of Citrus rootstocks

Endophytic Methylobacterium spp. were inoculated on citrus seed and evaluated for their ability to promote growth of Citrus limonia and Citrus sunki seedlings under commercial nursery conditions. The germination rate and seedlings growth differed according to the combination between Methylobacterium species and citrus rootstock, showing that the interaction depends on their compatibility. Methylobacterium had no effect...

Removal capacity of faecal pathogens from wastewater by four wetland vegetation: Typha latifolia, Cyperus papyrus, Cyperus alternifolius and Phragmites australis

The ability of four wetland vegetation: Typha latifolia, Cyperus papyrus, Cyperus alternifolius and Phragmites mauritianus in removing pathogenic and indicator microorganisms in the wetlands were studied in bucket experiments. The findings suggested that vegetated systems can effectively reduce faecal pathogens in wastewater. Both Salmonella species and Escherichia coli removal efficiencies were above 98%. This proved...

Molecular characterization and virulence of Beauveria bassiana and Metarhizium anisopliae against Galleria mellonella (Lepidoptera: Pyralidae) and Tenebrio molitor (Coleoptera: Tenebrionidae) larvae

Entomopathogenic fungi considerably vary in their action and virulence mode. The contamination mainly depends on the adhesion and penetration of the fungus in the host integument. Four isolates from Beauveria bassiana and Metarhizium anisopliae were molecularly characterized by rDNA-ITS sequencing. Their virulence against last instar larvae of Galleria mellonella and Tenebrio molitor at four conidia concentrations:...

Penicillium citrinum VFI-51 as biocontrol agent to control charcoal rot of sorghum (Sorghum bicolor (L.) Moench)

In our earlier investigation, a fungal isolate Penicillium citrinum VFI-51 and its secondary metabolite was reported to have antagonistic potential against Botrytis cinerea, the causative agent of Botrytis gray mold disease in chickpea. In the present investigation, P. citrinum VFI-51 was further evaluated for its antagonistic potential against Macrophomina phaseolina, the causative agent of charcoal rot in sorghum. P....
