摘要:
The present invention relates to a fungicidal and/or bactericidal composition comprising a combination of iturin and surfactin which are a cyclic peptide produced by a mircoorganism, preferably a microorganism belonging to the genus Bacillus, with an amphipathic organic material having a hydrocarbon chain, its production process and sterilization method using the same. The fungicidal and/or bactericidal composition of the present invention is highly safe to human body or environment, is free of generation of resistant bacteria even on repeated use and has a wide sterilization spectrum.
摘要:
(1) A method for producing iturin A and its homologues by cultivating a Bacillus microbe that produces iturin A and its homologue in a medium containing 2 mass % or more of soybean pulverisate or its extract as a nitrogen source to allow the microbe to accumulate iturin A and its homologue in the medium at a concentration of 1.5 g/L or more, (2) a culture containing iturin A and its homologue accumulated by the method, (3) a solid obtained from the culture and (4) a method of using the culture or the solid, are provided.
摘要:
A process for producing Surfactin, comprising culturing a microorganism of the genus Bacillus in a liquid culture medium containing flour of beans such as soybean or an extract thereof as a nitrogen source and accumulating Surfactin in the culture broth, and a microorganism of the genus Bacillus which have an activity to produce a crude Surfactin in a concentration of from 8 to 50 g/L on culturing for 20 to 90 hours.
摘要:
An agent for skin external use of the invention contains a salt of higher fatty acid ester of ascorbic acid-2-phosphoric acid ester and a polyhydric alcohol. According to the present invention, occurrence of turbidity or precipitation with time can be prevented to enhance stability even when the agent for skin external use is prepared using a specific salt of higher fatty acid ester of ascorbic acid-2-phosphoric acid ester. Therefore, the present invention is useful for all agents for skin external use, particularly cosmetics.

摘要:
Disclosed are: a novel catalyst for the hydrolysis of cellulose, which does not require the use of a large quantity of sulfuric acid for the preparation thereof and from which sulfuric acid cannot be eluted; a novel catalyst for the hydrolysis of cellulose, which is not changed in structure even in hot water and therefore does not undergo the deterioration in activity; and a process for producing a cellulose hydrolysate, mainly including glucose, using any one of the aforementioned catalysts. Specifically disclosed are: a catalyst for the hydrolysis of cellulose, which comprises a porous carbon material having a specific surface area of 800 to 2500 m2/g inclusive and a phenolic hydroxy group content of 100 to 700 mmol/kg inclusive, such as a porous carbon material having such a structure that carbon is filled in pores of mesoporous silica that is used as a template; and a catalyst for the hydrolysis of cellulose or hemicellulose, which comprises the aforementioned porous carbon material and a transition metal belonging to Group 8 to Group 11 and supported on the porous carbon material.
