Biocontrol Of Fusarium Wilt By Bacillus Pumilus, Pseudomonas Alcaligenes And Rhizobium Sp. On Lentil, Mohd Sayeed Akhtar, Uzma Shakeel, Zaki A. Siddiqui
Turkish Journal of Biology
The present study examined the effects of Bacillus pumilus, Pseudomonas alcaligenes, and Rhizobium sp. on wilt disease caused by Fusarium oxysporum f. sp. lentis and on the growth of lentil. Inoculation with F. oxysporum caused significant wilting, and reduced plant growth, the number of pods, and nodulation. Inoculation with B. pumilus together with P. alcaligenes caused a greater increase in plant growth, number of pods, nodulation, and root colonization by rhizobacteria, and also reduced Fusarium wilting to a greater degree than did individual inoculation. Use of Rhizobium sp. resulted in a greater increase in plant growth, number of pods, and …

Soil samples were collected from an industrial area in Kazanlı, Mersin, Turkey. Six heavy metals, Cr, Cu, Ni, Co, Cd, and Zn, were tested. ICP-AES analyses were carried out to detect the heavy metal levels of the soil samples. The analysis of test samples revealed high levels of Ni and Cr. A total of 272 Pseudomonas spp. and 161 Bacillus spp. strains were isolated from soils from 4 different sampling locations. The maximum tolerable metal concentrations (MTCs) of Cr, Cu, Ni, Co, Cd, and Zn for each isolate were determined. Resistance to Cr was found in 73.9% of the bacterial …
