The integration of probiotics in aquaponics systems is a strategy for mitigating environmental impacts and promoting sustainable agriculture. In order to understand the role probiotics, we investigated effect commercial probiotic mixture Bacillus subtilis B. licheniformis on growth lettuce (Lactuca sativa L.) under deep-water culture integrated with Mozambique tilapia (Oreochromis mossambicus)....

A total of 119 Bacillus thuringiensis strains (83 type strains and 26 native isolates), as well as five B. cereus group species, were analyzed by repetitive extragenic palindromic sequence-based PCR analysis (Rep-PCR) fingerprinting. Primers Bc-REP-1 and Bc-REP-2 were specifically designed according to an extragenic 26-bp repeated sequence found in the six B. cereus group genomes reported. A to...

C1 is an endospore forming gram-positive rod isolated from snow-covered soil in Massachusetts. Colonies were white and feathery in appearance and grew after 22 hours. The isolate was motile with ellipsoidal spores that are subterminal. The strain grew best at temperatures between 5-25 ̊ C with a pH range between 5–7 and NaCl concentration 1% (w/v). Phylogenetic analysis based on 16S rRNA gene se...

Bacillus strains are often isolated from biofilms in the food industries. Previous works have demonstrated that sporulation could occur in biofilms, suggesting that biofilms would be a significant source of food contamination with spores. In this study, we investigated the properties of mono-species and mixed Bacillus biofilms and the ability of Bacillus strains to sporulate inside biofilms. Ba...

The cilia-associated respiratory (CAR) bacillus is an unclassified, gram-negative, motile bacterium that has been implicated as an etiologic agent of respiratory disease in laboratory rodents. In the present study, approximately 1,200 bases of the 16S rRNA gene from three CAR bacillus isolates were sequenced. CAR bacillus-specific primers were designed on the basis of the 16S rRNA gene sequence...

Studies were carried out on the decolorization of azo dyes by Bacillus species from effluent of textile industries. About 10 bacterial strains were isolated from the effluent of textile industries, Bacillus sp. showed remarkable ability in decolorizing the widely utilized azo dyes. Phenotypic characterization and phylogenetic analysis based on 16S rDNA sequence comparisons indicate that these s...

Deoxyribonucleic acid-ribonucleic acid (DNA-RNA) and DNA-DNA hybridization studies were performed to determine the degree of genetic relatedness between Sarcina ureae and several members of the genus Bacillus. DNA-RNA hybridization showed a high degree of homology between S. ureae RNA and DNA from Bacillus species having a similar guanine plus cytosine content. The DNA from other genera of the ...

Spores of Bacillus megaterium, Bacillus cereus, and Bacillus subtilis were found to exhibit intrinsic paramagnetic properties as a result of the accumulation of manganese ions. All three Bacillus species displayed strong yet distinctive magnetic properties arising from differences in manganese quantity and valency. Manganese ions were found to accumulate both within the spore core as well as be...

Seventy five eye drops samples were collected from different pharmacies in Cairo, Egypt. Out of 75 tested samples, 58 (77.3%) are contaminated with bacterial growth when cultured on MYP medium. The bacterial count ranging from 1.0 CFU/ml to 6.0x10 CFU/ml. The microscopic examination indicated that 2 57 out of 133 isolates are Gram positive, spore forming bacilli. From 58 positive samples 32 sam...
