摘要:
A process for forming a fine pattern comprised of a polyhydroxyalkanoate on a substrate is provided. The process comprises steps of applying a polyhydroxyalkanoate-synthesizing enzyme and a 3-hydroxyacyl CoA to coexist in an intended pattern on a substrate, and polymerizing the 3-hydroxyalkanoate by action of the enzyme to form the polyhydroxyalkanoate in a pattern on the substrate. In particular, the fine pattern can be formed by an inkjet system.

A construct that comprises a base material and a polyhydroxyalkanoate, wherein at least a part of the base material is coated with the polyhydroxyalkanoate, and the polyhydroxyalkanoate comprises a 3-hydroxyalkanoic acid unit other than 3-hydroxypropionic acid unit, 3-hydroxy-n-butyric acid unit, and 3-hydroxy-n-valeric acid unit.In addition, an electrostatic charge image developing toner allows to design the toner characteristics such as chargeability, flowability, stability in time and environmental stability uniform among the toners of different colors. The toner has a small particle size enough for enabling uniform dispersion and being excellent in color saturation and transparency. The toner also shows higher contribution to the environmental security. The toner includes a coloring agent of which at least a part of the surface is covered with polyhydroxyalkanoate (PHA). The toner is produced by dispersing the coloring agent in aqueous medium, then fixing PHA synthesizing enzyme to the coloring agent dispersed in the aqueous medium, then adding 3-hydroxyacyl CoA, and executing a PHA synthesizing reaction to cover at least a part of the surface of the coloring agent with PHA. The toner thus obtained is used for an image forming method.

A method is provided for culturing a microorganism in a culture medium containing a carbon source and an electrolyzed water containing not more than 0.4 ppm chlorine produced during electrolyzing water containing an electrolyte in an electrolytic cell. The culture medium may also contain a carbon source and an acidic water having a pH value of 1-4 and a redox potential from 800 mV to 1500 mV. The acidic water is obtained by electrolysis of water in an electrolytic cell. Further, the culture medium may contain a carbon source and an alkaline water having a pH value of 10-13 and a redox potential from −1000 mV to 800 mV. The alkaline water is obtained by electrolysis of water in an electrolytic cell. The redox potential for the alkaline water is determined by the use of a platinum electrode as a working electrode and a silver-silver chloride electrode as a reference electrode. The microorganism may be selected from Escherichia coli, strain J1, strain JM2N, or an artificial recombinant. The microorganism can decompose a pollutant, such as phenol, toluene, cresol, trichlorethylene and dichloroethylene.
