Draft Genome Sequence of Glyphosate-Degrading Achromobacter insolitus Strain Kg 19 (VKM B-3295), Isolated from Agricultural Soil.

The genome of an strain isolated from an agricultural soil polluted with the herbicide glyphosate is reported. The genome size is 6.4 Mb, with an average G+C content of 65.

Organophosphonates utilization by soil strains of Ochrobactrum anthropi and Achromobacter sp.

Four bacterial strains from glyphosate- or alkylphosphonates-contaminated soils were tested for ability to utilize different organophosphonates. All studied strains readily utilized methylphosphonic acid and a number of other phosphonates, but differed in their ability to degrade glyphosate. Only strains Ochrobactrum anthropi GPK 3 and Achromobacter sp.

Glyphosate acetylation as a specific trait of Achromobacter sp. Kg 16 physiology.

The growth parameters of Achromobacter sp. Kg 16 (VKM B-2534 D), such as biomass and maximum specific growth rate, depended only on the source of phosphorus in the medium, but not on the carbon source or the presence of growth factors. With glyphosate as a sole phosphorus source, they were still 40-50 % lower than in media supplemented with orthophosphate or other organophosphonate-methylphosphonic acid.

[Microbial degradation of glyphosate herbicides (review)].

This review analyzes the issues associated with biodegradation of glyphosate (N-(phosphonomethyl)glycine), one of the most widespread herbicides. Glyphosate can accumulate in natural environments and can be toxic not only for plants but also for animals and bacteria. Microbial transformation and mineralization ofglyphosate, as the only means of its rapid degradation, are discussed in detail.

[The kinetic parameters of retainment and release of deposited in human tissue structures calcium].

The analysis of retainment and release kinetics of deposited in tissue structures calcium was made in the hypercalcemic conditions in 28 healthy volunteers (22 males and 6 females) of the age of 33 ± 6.5 years via drip infusion (Groups 1, 2) and in 9 individuals (3 males and 6 females) in 12 trials via stream infusion (Group 3). By the end of each hour after the termination of calcium infusion the amount of calcium retained in tissues was calculated (Mtis.
