Intrasporangium zincisolvens sp. nov., A Novel Actinobacterium Isolated from Rhizosphere Soil.

A novel phosphate-solubilizing and zinc-solubilizing actinobacterium strain YIM S08009 was isolated from rhizosphere soil collected from Pinus yunnanensis in Wuliangshan National Nature Reserve, Pu'er City, Yunnan Province, southwest PR China. Cells of strain YIM S08009 were Gram-stain-positive, non-motile, irregular rods to cocci, and formed yellow and white colonies on nutrient agar. Growth was observed at 10-40 °C (optimum 25-35 °C), pH 6.

Solibacillus ferritrahens sp. nov., a novel siderophore-producing bacterium isolated from Wumeng Mountain National Nature Reserve in Yunnan Province.

A gram-stain-positive, aerobic, rod-shaped bacterial strain capable of producing siderophores, named YIM B08730, was isolated from a soil sample collected from Wumeng Mountain National Nature Reserve, Zhaotong City, Yunnan Province. Growth occurred at 10-45 °C (optimum, 35-40 ℃), pH 7.0-9.

Chitinolyticbacter albus sp. Nov., A Novel Chitin-Degrading Bacterium Isolated from Ancient Wood Rhizosphere Soil.

In this study, a novel aerobic mesophilic bacterial strain with capable of degrading chitin, designated YIM B06366, was isolated and classified. The rod-shaped, Gram-stain-negative, on-spore-forming bacterium originated from rhizosphere soil sample collected in Kunming City, Yunnan Province, southwest PR China. Strain YIM B06366 exhibited growth at temperatures between 20 and 35 °C (optimum, 30 °C) and at pH 6.

Pseudomonas subflava sp. nov., a new Gram-negative bacterium isolated from Guishan in Yunnan province, south-west China.

A new Gram-negative, rod-shaped, flagellated bacterium was isolated from soil in the Guishan, Xinping County, Yuxi City, Yunnan Province, China, and named YIM B01952. Growth occurred at 10-40 °C (optimum, 30 °C), pH 6.0-9.

Brevibacillus daliensis sp. nov., Isolated From Soil in Machangqing Nature Reserve.

A new aerobic bacterial strain, designated strain YIM B02290, was isolated from the soil of Machangqing, Dali city, Yunnan Province, China. Cells were Gram-stain-positive, sporogenous, rod-shaped, and motile with peritrichous flagella. Strain YIM B02290 showed the highest 16S rRNA gene sequence similarity with Brevibacillus laterosporus (97.

Cohnella mopanensis sp. nov., a new Gram-negative bacterium isolated from soil in Xinping Mountain National Forest Park.

A Gram-stain-negative, aerobic, rod-shaped bacteria strain, named YIM B01951, was isolated from a forest soil sample collected from Mopan Mountain National Forest Park, Xinping City, Yunnan Province, southwest PR China (101°58'06" N, 23°03'02" E). Growth occurred at 15-40 °C (optimum, 30 °C), pH 5.0-8.

[Mechanism on biodiversity managing crop diseases].

Reasonable utilization of natural resource and protection of ecological environment is the foundation for implementing agricultural sustainable development. Biodiversity research and protection are becoming an important issue concerned commonly in the world. Crop disease is one of the important natural disasters for food production and safety, and is also one of the main reasons that confine sustainable development of agricultural production.
