Novel cellulose-producing bacteria including one capable of producing of a bacterial cellulose having a weight-average degree of polymerization in terms of polystyrene of 1.6&times;10 or above, one capable of producing a bacterial cellulose containing a small amount of the fraction with low degrees of polymerization, one producing a Bingham polysaccharide as a by-product, and one producing a small amount of water-soluble polysaccharide; a method for the production of bacterial cellulose, which comprises culturing these cellulose-producing bacteria; and bacterial cellulose thus obtained.

Cellulose-producing bacteria

Gene, group of genes, and novel &bgr;-glucosidase

The present invention provides a method for isolating a microbe whereby a sample of microbe cells is encapsulated in agarose gel particulates, wherein some of the particulates contain a single cell, and the other particulates contain more than one cell; incubating the particulates in nutritional and environmental conditions that enable the microbe contained in the sample solution that can grow on a plate of a plate culture method to grow in the agarose gel particulate; and isolating the particulates having single cells from the group of the particulates having more than one cell.

Culturing an L-amino acid producing microorganism belonging to the genus Brevibacterium or Corynebacterium and having a resistance to a peptide containing glutamic acid or aspartic acid gives L-amino acids in high yield.

Process for producing L-amino acids by fermentation

Acetic acid bacterium, plasmid derived from said bacterium and shuttle

A method of producing trehalose, in which a microorganism belonging to the genus Brevibacterium, Corynebacterium, Microbacterium or Arthrobacter and having the ability to produce trehalose is incubated in a liquid medium containing sucrose or maltose as an essential carbon source and the trehalose produced and accumulated in the culture is collected therefrom. Trehalose is produced inexpensively and efficiently by industrial mass-production.

Method of producing trehalose by microorganisms which can produce

A method for increasing .beta.-tyrosinase activity in Erwinia herbicola is disclosed. The activity is increased by culturing the microorganism until it reaches stationary phase and maintaining the stationary phase for a period of 6 to 24 hours while maintaining the pH between 7.0 and 8.3.

Method for increasing beta-tyrosinase activity in Erwinia herbicola

The present invention relates to improved methods for producing L-3, 4-dihydroxyphenylalanine from catechol, pyruvic acid and ammonium ion, or catechol and L-serine, by utilizing .beta.-tyrosinase activity of a microorganism which belongs to the genus Erwinia. According to the method of the present invention, L-3,4-dihydroxyphenylalanine can be produced at a lower cost and higher efficiency as compared with that in the conventional method.

Method for producing L-3, 4-dihydroxyphenyalanine by Erwinia having
