Whole genome analysis, thermal and UV-tolerance of Lactococcus phage BIM BV-114 isolated from cheese brine.

Lactococcus phages that belong to the genus Ceduovirus are among the three most frequently isolated phage groups infecting Lactococcus lactis starter strains in dairy plants. In this study, we characterized virulent Lactococcus phage BIM BV-114 isolated from industrial cheese brine in Belarus and identified as Ceduovirus. The bacteriophage demonstrated a relatively short lytic cycle (latent period of 23 ± 5 min, lysis time of 90 ± 5 min), high thermal stability (inactivation after 7 min at 95 °C in skimmed milk) and tolerance to UV radiation (inactivation time - 15 min), indicating adaptation for better persistence in dairy facilities.

sp. nov., isolated from freshwater.

A Gram-stain-negative, rod-shaped, amylolytic bacterial strain, designated as bsSlp3-1, was isolated from the Slepian water system, a freshwater reservoir. Strain bsSlp3-1 was found to be aerobic, oxidase-positive and catalase-negative, grew at 5-37 °C (optimum, 28 °C), pH 5.0-9.

Isolation and characterization of fast-growing green snow bacteria from coastal East Antarctica.

Snow microorganisms play a significant role in climate change and affecting the snow melting rate in the Arctic and Antarctic regions. While research on algae inhabiting green and red snow has been performed extensively, bacteria dwelling in this biotope have been studied to a much lesser extent. In this study, we performed 16S rRNA gene amplicon sequencing of two green snow samples collected from the coastal area of the eastern part of Antarctica and conducted genotypic and phenotypic profiling of 45 fast-growing bacteria isolated from these samples.

Complete Genome Sequence of Pseudomonas putida BS3701, a Promising Polycyclic Aromatic Hydrocarbon-Degrading Strain for Bioremediation Technologies.

The strain BS3701 was isolated from soil contaminated with coke by-product waste (Moscow Region, Russian Federation). It is capable of degrading crude oil and polycyclic aromatic hydrocarbons (PAHs). The BS3701 genome consists of a 6,337,358-bp circular chromosome and two circular plasmids (pBS1141 with 107,388 bp and pBS1142 with 54,501 bp).

Isolation and characterization of Hena1 - a novel Erwinia amylovora bacteriophage.

Fire blight, caused by plant pathogenic bacterium Erwinia amylovora, is one of the most important diseases of Rosaceae plants. Due to the lack of effective control measures, fire blight infections pose a recurrent threat on agricultural production worldwide. Recently, bacterial viruses, or bacteriophages, have been proposed as environmentally friendly natural antimicrobial agents for fire blight control.

Complete Genome Sequence of Rhodococcus erythropolis X5, a Psychrotrophic Hydrocarbon-Degrading Biosurfactant-Producing Bacterium.

X5 is a psychrotrophic (cold-adapted) hydrocarbon-degrading bacterium, as it showed effective -alkane destruction at low positive temperatures. Here, the genome of strain X5 was completely sequenced; it consists of a 6,472,161-bp circular chromosome (62.25% GC content) and a 526,979-bp linear plasmid, pRhX5-526k (62.
