They have found that acrylamide with improved qualities can be produced, and have completed the present invention.
- the present invention provides a method for producing acrylamide using a microbial catalyst for converting acrylonitrile to acrylamide, wherein the microbial catalyst washed with an aqueous acrylic acid solution is used as the microbial catalyst. It is a manufacturing method.
- the microbial catalyst that can be used in the present invention may be any microbial catalyst prepared from a microorganism having a catalytic activity of converting acrylonitrile to acrylamide (nitrile hydratase activity). Examples of the microorganism species include Bacillus, Bacteridium, Micrococcus, Brevibacterium, and Corynebacterium.
- Genus Nocardia genus, Pseudomonas genus, Microbacterium genus, Rhodococcus genus, Achromobacter genus Microorganisms belonging to the genus Pseudonocardia) are preferred.
- the microorganisms can be used alone or in combination.
- a transformant in which the nitrile hydrase gene derived from the microorganism is obtained, and is directly or artificially improved, and the gene is introduced into an arbitrary host may be used.
- Examples of the transformants include Escherichia coli MT10770 (FERM P-14756) (Japanese Unexamined Patent Publication No. 8-266277) transformed with nitrile hydratase of the genus Achromobacter, and nitriles of the genus Pseudonocardia.
- E. coli MT10822 (FERM BP-5785) transformed with hydratase (JP-A-9-275978) or nitrile hydrazine of Rhodococcus rhodoctirous species (JP-A-4-211379). Transformed microorganisms are preferred.
- the method for culturing the microorganism can be carried out by an appropriate method depending on the species of the microorganism.
- microbial catalyst prepared from microorganisms refers to the cultivation of microorganisms. Culture solution obtained, cells obtained by collecting cells, etc., crushed cells obtained by crushing cells by ultrasonic treatment, etc., crude enzyme prepared after crushing cells, partially purified enzyme or purified enzyme It means. These microbial catalysts may be immobilized on a carrier such as polyacrylamide gel, alginate, carrageenan, or ion exchange resin, if necessary. The use form of the microbial catalyst is appropriately selected depending on the stability of the enzyme, the production scale, and the like.
- washing refers to washing of the microorganism cells after culture and Z or the microbial catalyst used in the reaction. Therefore, in the washing, both the microorganism cells after the culturing and the microbial catalyst used in the reaction may be washed with acrylic acid, or only the microbial catalyst used in the reaction may be washed with acrylic acid.
- the microbial catalyst used in the reaction may be washed once with water, a buffer, or the like, and then washed with acrylic acid before being subjected to the reaction. 'The microbial catalyst only needs to be washed with acrylic acid immediately before the reaction.
- any washing method may be used.
- a method of repeating washing and centrifugation, a method of washing with a hollow fiber membrane, and the like can be exemplified.
- the immobilized microorganism catalyst when washed, it can be carried out by repeating stirring, sedimentation, and supernatant removal of the immobilized catalyst in the washing solution.
- the washing method and the number of washings can be appropriately set in consideration of washing efficiency, enzyme stability, and the like.
- the concentration of acrylic acid used at the time of washing is preferably from 0.01% by mass to 10% by mass in an aqueous acrylic acid solution. More preferably, it is 0.05% by mass to 1% by mass, and most preferably 0.1% by mass.
- the concentration of acrylic acid is 0.01% by mass or less, the washing time and the number of washings increase, and the operation becomes complicated. In addition, an increase in the number of washings may cause breakage of the cells during the washing and collapse of the immobilized cells. If the content is more than 10% by mass, the enzyme activity is lowered, which is not preferable. It is also not economically favorable.
- the pH of the aqueous acrylic acid solution is adjusted using sodium hydroxide, ammonia, or the like. Preferably, the pH is adjusted to 5-11, more preferably 6-10, most preferably 7.
- the microbial catalyst prepared as described above can be used as a microbial catalyst in a state of being suspended or dispersed in an aqueous acrylic acid solution or in a state of being subjected to solid-liquid separation.
- Rhodococcus rhodochrous Jl (FERM BP-1478) (described in Japanese Examined Patent Publication No. 6-55148) having nitrile hydratase activity was treated with a 30 L volume jar mentor (manufactured by Takasugi Mfg. Co., Ltd.) at 2% glucose.
- the cells were cultured aerobically for 60 hours at a temperature of 30 in a medium (pH 7.0) containing 1% by weight of urea, 5% by weight of peptone, 0.3% by weight of yeast extract, and 0.05% by weight of cobalt chloride.

Thereafter, 0.0004% of ammonium persulfate, 0.0004% of iron sulfate, and 0.01% of 4,4,4-azobis- (4-cyanovaleric acid) were added, and polymerization was carried out.
- the obtained hydrogel polymer is crushed into particles having a diameter of several mm with a meat grinder, dried at 80 for 10 hours, and ground with a wheel mill to a particle size of 2 mm or less. I got
- the obtained polymer powder was adjusted to a concentration of 0.2% with 500 g of water, stirred at room temperature for 4 hours and dissolved, and then subjected to Brookfield viscosity (B-type viscometer, rotor rotation speed 30 rpm, rotor No. 1). ) was measured. Then, the mixture was filtered through an 80-mesh wire gauze, washed with water, and the mass of insoluble matter remaining on the wire gauze was measured.
- Example 1 Put 50 g of the 50% aqueous solution of acrylamide monomer obtained in Example 1 (3) and an iron test piece into a 100 ml polyethylene bottle, and close the lid to prevent evaporation. did. This was stored in a high-temperature box at 50 ° C., and the stability was determined based on the presence or absence of the polymer.
