Isolation and Characterization of Halotolerant Plant Growth Promoting Rhizobacteria From Durum Wheat ( subsp. ) Cultivated in Saline Areas of the Dead Sea Region.

Plant growth promoting rhizobacteria (PGPR) are beneficial microorganisms that can be utilized to improve plant responses against biotic and abiotic stresses. In this study, 74 halotolerant bacterial isolates were isolated from rhizosphere and endorhizosphere of durum wheat ( subsp. ) plants cultivated in saline environments in the Ghor region near the east of the Dead Sea.

Incidence and characterization of diarrheal enterotoxins of fecal Bacillus cereus isolates associated with diarrhea.

A total of 490 stool specimens were collected from patients with diarrhea and healthy controls without diarrhea to investigate the incidence of Bacillus cereus and its enterotoxins. B. cereus was found more significant in stools of persons with diarrhea than without diarrhea (9.

Characterization of Bacillus thuringiensis ser. jordanica (serotype H71), a novel serovariety isolated in Jordan.

The novel strain of Bacillus thuringiensis J112 isolated from a soil sample in Jordan was classified and characterized in terms of toxicity against dipteran and nematode larvae, crystal protein pattern, plasmid profile, and cry gene content. A new name, Bacillus thuringiensis serovariety jordanica (H serotype 71), is proposed for the reference strain J112. The parasporal crystal proteins were toxic to 3(rd) instar larvae of Drosophila melanogaster and to 2(nd) stage juveniles of root knot nematodes Meloidogyne javanica and M.

Toxicity of Bacillus thuringiensis and B. sphaericus to laboratory populations of Drosophila melanogaster (Diptera: Drosophilidae).

A total of 65 samples, consisting of 8 sample types, collected from the Jordan Valley, were examined for the presence of Bacillus thuringiensis and B. sphaericus and for their toxicity against the larvae of the fruit fly Drosophila melanogaster. The frequency of samples containing toxic aerobic spore-forming bacilli was 12%; of which 21.
