The methods suggested for the identification of species of the genus Bacillus in the invaluable monographs of Smith et al. (1946, 1952) have been applied to a collection of named cultures, and also have been utilized for the classification of approximately 400 strains of these organisms isolated from samples of blood, spinal fluid, surgical tissue, and other human and animal sources, as well as...

AIM To investigate the effect of oral administration of two Bacillus strains on fecal coliforms, Lactobacillus and Bacillus spp. in rat animal model. MATERIALS AND METHODS An in vivo experiment was conducted for 49-day period on 36 adult male albino Wister rats divided equally into to four groups. After 7-day adaptation period, one group (T1) was fed on sterile skim milk along with basal diet...

This study was to isolate, screen, and identify microorganisms from fermented food Red Oncom and Tempeh Gembus that can produce fibrinolytic proteases. Forthy-three isolates showed proteolytic activities on skim milk agar, while thirthy-eight of them showed fibrinolytic activities both on a fibrin plate and a fibrinogen zymography. The isolates that showed activity in fibrin plate and fibrinoge...

Plasmid pSL103 was previously constructed by cloning a Trp fragment (approximately 2.3 X 10(6) daltons) from restriction endonuclease EcoRI-digested chromosome DNA of Bacillus pumilus using the neomycin-resistance plasmid pUB110 (approximately 2.8 X 10(6) daltons) as vector and B. subtilis as transformation recipient. In the present study the EcoRI Trp fragment from pSL103 was transferred in vi...

Background: Enantiopure epoxides are important intermediates in the synthesis of high-value chiral chemicals. Epoxide hydrolases have been exploited in biocatalysis for kinetic resolution of racemic epoxides to produce enantiopure epoxides and vicinal diols. It is necessary to obtain sufficient stable epoxide hydrolases with high enantioselectivity to meet the requirements of i...

BACKGROUND In this study, we attempted to screen and investigate antibacterial activity of Bacillus species, which were isolated from conjunctiva, against other eyes pathogens. METHODS To examine predominant isolates of Bacillus subtilis, B. pumilus, B. cereus and B. mojevensis, isolated from conjunctiva for their antimicrobial activity against indicator microorganisms as Micrococcus luteus, ...

Spore-forming microbes recovered from spacecraft surfaces and assembly facilities were exposed to simulated Martian UV irradiation. The effects of UVA (315 to 400 nm), UVA+B (280 to 400 nm), and the full UV spectrum (200 to 400 nm) on the survival of microorganisms were studied at UV intensities expected to strike the surfaces of Mars. Microbial species isolated from the surfaces of several spa...

Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), the Mediterranean fruit fly (medfly), is one of the most important fruit pests worldwide. The medfly is a polyphagous species that causes losses in many crops, which leads to huge economic losses. Entomopathogenic bacteria belonging to the genus Bacillus have been proven to be safe, environmentally friendly, and cost-effective tools to cont...
