Bdellovibrio-and-like organisms (BALOs) are predatory bacteria that prey upon Gram-negative bacteria and are taxonomically subsumed in the order Bdellovibrionales. Despite their unique lifestyle, these bacteria show remarkable genotypic diversities. The outer membrane of the predators is likely to play an important role during the recognition and invasion stage, as well as in the intraperiplasm...

The goals of this work are to characterize and evaluate the ability of strain OU40 to produce poly (3-hydroxybutyrate-co-3-hydroxyvalerate)(PHBV) using various agricultural wastes, isolated from polluted water.Growth of the isolate OU40 was assessed in mineral media containing glucose, starch, bagasse, whey and rice bran without adding any precursors. Biopolymers produced by strain OU40 had an ...

A Gram-negative strain, B11(T), was isolated from tidal flat sediment in Yeosu, Republic of Korea. Strain B11(T) did not require NaCl for growth and grew between 18 and 44 degrees C. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain B11(T) was associated with the genus Alishewanella and was closely related to the type strain of Alishewanella fetalis (98.3 % similarity). ...

The genetic diversity of antagonistic bacteria from the tobacco rhizosphere was examined by BOXAIR-PCR, 16S-RFLP, 16S rRNA sequence homology and phylogenetic analysis methods. These studies revealed that 4.01% of the 6652 tested had some inhibitory activity against Phytophthora nicotianae. BOXAIR-PCR analysis revealed 35 distinct amplimers aligning at a 91% similarity level, reflecting a high d...

Citrobacter freundii is a zoonotic pathogen that causes skin injuries and high mortality rates in fish. This study aims to determine the presence of C. antibiotic susceptibility 50 goldfish (Carassius auratus) wounds with local bleeding between ages 8–18 months three regions (A, B, C) located West Turkey. (22/50; 44%) strains were isolated from wound swab samples by phenotypic genotypic methods...

The bacterium Acidovorax avenae causes disease in a wide range of economically important monocotyledonous and dicotyledonous plants, including corn, rice, watermelon, anthurium, and orchids. Genotypic and phenotypic relatedness among strains of phytopathogenic A. avenae subsp. avenae, A. avenae subsp. citrulli, A. avenae subsp. cattleyae and A. konjaci, as well as all other Acidovorax species, ...

A moderate halophilic bacterium was isolated from the brine samples of Sambhar salt lake, Rajasthan (India). The isolate formed pigmented colonies and the bacterial cells are motile, Coccoid, Gram positive, strictly aerobic, catalaseand oxidasepositive, ferments carbohydrates, while failed to utilize citrate as sole carbon source. The isolate grew in presence of 2-20% (w/v) NaCl and at pH 7-11,...

The novel, Gram-stain-positive, ovoid, lactic acid bacterial isolates LMG 27205, LMG 27206, LMG 27207(T) and MRI-F 18 were obtained from throat samples of healthy humans. 16S rRNA gene sequence analyses indicated that these isolates belong to the genus Streptococcus, specifically the Streptococcus mitis group, with Streptococcus australis and Streptococcus mitis as the nearest neighbours (99.45...

Two mating-type genes, designated MAT1-1-1 and MAT1-2-1, were cloned and sequenced from the presumed asexual ascomycete Cladosporium fulvum (syn. Passalora fulva). The encoded products are highly homologous to mating-type proteins from members of the Mycosphaerellaceae, such as Mycosphaerella graminicola and Cercospora beticola. In addition, the two MAT idiomorphs of C. fulvum showed regions of...

Natural selection operates both directly, via the impact of a trait upon the individual's own fitness, and indirectly, via the impact of the trait upon the fitness of the individual's genetically related social partners. These effects are often framed in terms of Hamilton's rule, rb - c > 0, which provides the central result of social-evolution theory. However, a number of studies have question...
