Аннотация:Prosthecomicrobium consociatum Vasil’eva L.V., Semenov A. M. & Giniyatullina A. I. sp. nov. Strain 11 (5VKM B-24985CCM 7594)DD 2 17: Cells are short, thick rods, 0.5–1.0 μm in diameter and 0.8–1.35 μm in length. Prosthecae are 0.2 to 0.25 μm in length and arranged in five rows along cells. End view of cells shows a five-pointed star. Non-motile. Reproduce by budding. Aerobic and catalase- and oxidase-positive. Chemoheterotrophic. Uses some monosaccharides as carbon and energy sources for growth. Does not hydrolyse cellulose or other polysaccharides. Some sugar alcohols, organic acids of the TCA cycle and methanol and methylamine can be used as carbon sources. Yeast extract or B-vitamins are required for growth. Optimum growth temperature is 28–30 °C at neutral pH. Colonies are small (up to 1 mm in diameter) and grey with an entire margin. Widespread in soil habitats and compost where cellulolytic activity is high. The DNA G+C content of the type strain is 66.0–68.5 mol% (Tm).
The type strain is strain 11T (=VKM B-2498T =CCM 7594T).
Prosthecomicrobium mishustinii Vasil’eva L.V., Semenov A. M. & Giniyatullina A. I. sp. nov. Strain 17 (5VKM B-24995CCM 7569)dd 2 17: Cells are thick, short rods, 0.6–1.2 μm in diameter and 0.8–1.5 μm in length. Cells are unicellular or paired. Non-motile. Prosthecae are from 0.2 to 0.65 μm in length. Cells reproduce by budding. Cells are aerobic and catalase- and oxidase-positive. Uses many mono- and disaccharides and sugar alcohols, some organic acids as well as amino acids as energy sources for growth. Yeast extract or B-vitamins are required for growth. Optimum growth temperature range is 28 to 30 °C at neutral pH. Colonies are yellowish-orange, have an entire margin and a thick consistency so that they can be removed from agar medium. Colony variants lacking pigment may be produced. Widespread in soil, manure and other organically enriched habitats. The DNA G+C content of the type strain is 63.7–65.2 mol% (Tm). The type strain is strain 17T (=VKM B-2499T =CCM 7569T).
