    摘要： This invention provides an Amycolatopsis sp. strain (zhp06), and a method of using the whole cell preparation of the strain for vanillin production. The strain was deposited in China Center for Type Culture Collection on Jul. 26, 2011 with the number of CCTCC NO: M 2011265. Under high concentrations of ferulic acid substrate, the vanillin production by this method can reach more than 10 g/L. The molar conversion rate of ferulic acid is more than 50% and the purity of vanillin is from 80% to 95%. The advantage of this invention includes: repeated use of biocatalyst cells, mild biotransformation condition, low environmental pollution, short production cycle, high product purity and simple purification procedure. It has a great potential for industrial applications.

    摘要： [Problem]To provide a bacterial cellulose which is highly dispersible in a liquid, shows excellent molding properties and high miscibility with other materials when applied to materials, and, therefore, has a high applicability as a practical material, and a bacterium which produces the bacterial cellulose.[Solution]A bacterial cellulose, water that contains said bacterial cellulose at a final concentration of 0.1±0.006 (w/w) showing a light transmittance at a wavelength of 500 nm of 35% or greater, and a bacterium producing the bacterial cellulose. According to the present invention, the bacterial cellulose that is uniformly dispersible in a liquid such as water can be obtained. The bacterial cellulose shows excellent molding properties and high miscibility with other materials and, therefore, can contribute to the improvement in the qualities of a final product or production efficiency thereof or to the reduction of production cost.
