Abstract: In the production and collection of a product through fermentation using a separation membrane, it becomes possible to retain filter performance for the high-concentration culturing of a microbe mixture, and at the same time control microbe concentrations, by a method for producing chemicals through continuous fermentation, including washing a membrane with a washing liquid supplied from a permeate side of a membrane unit in a continuous fermentation including: filtering a culture medium containing a fermentation feedstock, a chemical and a microbe or a cultured cell through a separation membrane; collecting the chemical from a filtrate; retaining or refluxing unfiltered remains in the culture medium; and adding a fermentation feedstock to the culture medium, in which the washing liquid is high-temperature water having a temperature higher than a temperature of the culture medium and of 150°C or less, and a concentration of the microbe in a fermenter is controlled by supplying the washing liquid.

Abstract: A method for producing a chemical through continuous fermentation, the method including: (a) culturing a cell in a culture medium in a fermentor to ferment a feedstock to produce a chemical; (b) conducting filtration of the culture medium by using a separation membrane module; (c) separating a permeate containing the chemical from the culture medium while retaining a non-permeated liquid in the fermentor, and (d) supplying a gas from at least one of a lower portion of the separation membrane module and a pipe communicating between the fermentor and the separation membrane module so as to adjust a gas linear velocity in the separation membrane module to 0.15 cm/s to 70 cm/s while supplying the separation membrane module with a liquid.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject spun yarn recyclable easily, benign to the environment even if burnt, having bulky and soft feel and excellent in openability and dyeability, by including specific flat polyester short fibers. SOLUTION: This polyester spun yarn comprises polyester short fibers (each with an average fineness of pref. =30 (pref. >=50) wt.% of the total constituent short fibers, and furthermore, the variance of boiling water shrinkage among the constituent short fibers is >=4.0 (pref. >=8.0) % and the short fibers with higher boiling water shrinkage account for >=20 (pref. >=30) % of the total constituent short fibers.
