Orrella daihaiensis sp. nov., a bacterium isolated from Daihai Lake in Inner Mongolia.

A novel aerobic, Gram-staining-negative, non-motile, short-rod-shaped strain, designated f23, was obtained from Daihai Lake, Inner Mongolia, Republic of China. 16S rRNA gene sequences analysis showed that f23 belongs to the genus Orrella and is most closely related to Orrella marina H-Z20 with 98.35% sequence similarity.

[A new discrimination method of maize seed varieties based on near-infrared spectroscopy].

A new discrimination method for the maize seed varieties based on the near-infrared spectroscopy was proposed. The reflectance spectra of maize seeds were obtained by a FT-NIR spectrometer (12000-4000 cm(-1)). The original spectra data were preprocessed by first derivative method.
