Changes of the main components, physicochemical properties of distiller's grains after extrusion processing with focus on modification mechanism.

Distiller's grains (DGs) possessed great potential utilization value due to their rich active ingredients. However, its utilization efficiency was limited by the large amount of lignocellulose components and water-insoluble proteins. In this work, single screw extrusion was applied to modify physicochemical properties of DGs.

Scopulibacillus daqui sp. nov., a thermophilic bacterium isolated from high temperature daqu.

A Gram-stain-positive, facultatively anaerobic, thermophilic bacterium, designated ZQ18-1T, was isolated from a high temperature daqu sample collected from the sesame-flavour liquor-making process. Oval endospores were formed at the centre of cells with swollen sporangia. The isolate was able to grow at temperatures of 20-60 °C (optimum growth at 50 °C), at pH 4-9 (optimum growth at pH 8) and in the presence of 0-10 % (w/v) NaCl (optimum growth with 2 % NaCl).

Genome Sequence of Thermoactinomyces daqus H-18, a Novel Thermophilic Species Isolated from High-Temperature Daqu.

Thermoactinomyces daqus H-18 is a new species of Thermoactinomyces isolated from high-temperature Daqu used in the fermentation of Bandongjing sesame-flavor liquor. Its genome was sequenced and assembled (3.44 Mb).

Thermoactinomyces daqus sp. nov., a thermophilic bacterium isolated from high-temperature Daqu.

Daqu is a fermentation starter used in the production of Chinese liquors. A thermophilic bacterium, designated strain H-18(T), was isolated from a high-temperature Daqu sample collected from the manufacturing process of a sesame-flavoured liquor in Shandong province, China. It was investigated in a taxonomic study using a polyphasic approach.
