Fungal infections cause heavy losses to plants and are usually controlled using common fungicides, which cause environmental pollution and affect health. Thus, the study aims to isolate and identify the highly active chitinolytic endophytic actinomycetes from healthy cucumber plants and evaluate their biological activity against soil-borne pathogen...

This study evaluated the activity of a newly identified endophytic actinobacterium strain Streptomyces rochei OM182844 as an antifungal agent against soil-borne pathogenic fungi, Fusarium oxysporum f.sp. cucumerinum, Sclerotinia rolfsii, and Pythium aphanidermatum. The antifungal activity was performed using Strep. rochei culture and its crude cult...

A consortium of three heavy metals tolerant-plant growth promoting bacteria (HMT-PGPB) (Bacillus cereus MG257494.1, Alcaligenes faecalis MG966440.1 and Alcaligenes faecalis MG257493.1) was tested for its beneficial effects on microbial activities in sorghum’ rhizosphere (Sorghum vulgare L.). Moreover their ability to reduce heavy metals bioaccumula...

This study was designed under laboratory conditions to isolate, identify and characterize some cadmium-tolerant bacteria from heavy metals-contaminated regions of Egypt. These regions included three sites along Al-Rahawy drain, Giza Governorate and two agricultural soils from Kaluybia Governorate, Egypt. Three of sixty-nine cad-mium-tolerant bacter...

This study aimed to evaluate three heavy metal tolerant bacterial strains (HMTB) namely Alcaligenes faecalis MG257493.1, Bacillus cereus MG257494.1 and Alcaligenes faecalis MG966440.1 as antioxidant agents and plant growth promotors under laboratory conditions. Their abilities to inhibit 2,2-DiPhenyl-2-Picrylhydrazyl hydrate (DPPH) as non-enzymatic...

A green-house experiment was conducted to investigate the efficiency of three heavy metal-tolerant plant growth promoting bacterial strains (HMT-PGPB) (Alcaligenes faecalis MG257493.1, Bacillus cereus MG257494.1 and Alcaligenes faecalis MG966440.1 to alleviate the heavy metal's toxic effects on sorghum plant (Sorghum bicolor, L.) in addition to the...

A total of 71 zinc tolerant bacteria were ,isolated from Four heavy metals contaminated sediments and soils in Egypt, three sediment samples (Upstream, midstream, downstream Al-Rahawy drain, Giza Governorate) and two agricultural soil samples (Al-Gabal Al-Asfar region and Kafr-Ilwan village, Qalubia Governorate). The minimum inhibitory concentratio...

The aim of this study was to isolate and identify of some heavy metals-tolerant bacteria from different heavy metals contaminated sites in Egypt to be used as bioremoval agents as well as plant growth promoters. Additionally, studying the efficiency of those strains on sorghum growth performance in heavy metals contaminated soil. This study was div...
