Linear Six-Carbon Sugar Alcohols Induce Lysis of NIES-298 Cells.

Cyanobacterial blooms are a global concern due to their adverse effects on water quality and human health. Therefore, we examined the effects of various compounds on growth. We found that NIES-298 cells were lysed rapidly by linear six-carbon sugar alcohols including mannitol, galactitol, iditol, fucitol, and sorbitol, but not by other sugar alcohols.

sp. nov., isolated from soil.

A strict aerobic bacterium, strain JW14 was isolated from soil in the Republic of Korea. Cells were Gram-stain-positive, non-endospore-forming and motile rods showing catalase-positive and oxidase-negative activities. Growth of strain JW14 was observed at 20-37 °C (optimum, 30 °C), pH 6.

sp. nov., isolated from a culture of .

Strain MaA-C15, a Gram-stain-negative, non-spore-forming and strictly aerobic bacterium, was isolated from a xenic culture of in the Republic of Korea. Cells were motile rods showing positive reactions in catalase and oxidase tests. Growth was observed between 15 and 37 °C (optimum, 30 °C), between pH 6.

sp. nov., isolated from seawater and reclassification of as a later heterotypic synonym of .

A Gram-stain-negative, orange-pigmented and strictly aerobic bacterium, designated strain MJ115, was isolated from seawater in Pohang, South Korea. Cells were non-motile rods and showed positive reactions for catalase and oxidase tests. Growth of strain MJ115 was observed at 4-35 °C (optimum, 30 °C), pH 6.

sp. nov. and sp. nov., isolated from soil.

Two Gram-stain-negative, facultative anaerobic and non-motile bacteria, strains R11 and S1162, were isolated from soil in the Republic of Korea. Both strains were catalase- and oxidase-positive and contained menaquinone-7 as the major isoprenoid quinone. Strain R11 contained summed feature 3 (C ω7 and/or C ω6), iso-C, C and iso-C 3-OH as major fatty acids and phosphatidylethanolamine, an unidentified aminophospholipid and an unidentified aminolipid as major polar lipids; while strain S1162 contained summed feature 3 (C ω7 and/or C ω6), iso-C, iso-C 3-OH, C and summed feature 9 (10-methyl C and/or iso-C ω9) as major fatty acids and phosphatidylethanolamine and an unidentified aminophospholipid as major polar lipids.

Flavihumibacter soli sp. nov., Isolated from Soil.

A novel Gram-stain-positive, strictly aerobic, non-motile, rod-shaped bacterium, designated strain R14T was isolated from steep grove soil and taxonomically characterized using a polyphasic approach. Cells showed oxidase-negative and catalase-positive activities and grew at 25-37 °C (optimum, 30 °C), pH 5.0-8.

sp. nov., isolated from a culture of .

A Gram-stain-negative, yellow-pigmented, strictly aerobic bacterium, designated strain MaA-Y11, was isolated from a culture of in the Republic of Korea. Cells were non-motile rods showing catalase- and oxidase-positive reactions. Growth of strain MaA-Y11 was observed at 25-37 °C (optimum, 30 °C) and pH 6.
