An aflatoxin contamination inhibitor, which contains an actibiotic Blasticidin A of the following chemical formula (1) or its salt, ##STR1## and at least one selected from a solid carrier, a liquid carrier and an emulsion dispersant; and a method for inhibiting aflatoxin contamination by spraying a chemical containing from 10 to 5,000 ppm of the Blasticidin A or its salt on plants.

Aflatoxin contamination inhibitor and aflatoxin contamination-inhibiting

The antibiotic aflastatin A or its salt and its production by Streptomyces sp. MRI 142, FERM BP-5841 is presented. Aflastatin A is incorporated into a pharmaceutical composition and is employed as an aflatoxin contamination inhibitor, antimicrobial agent, antifungal agent and antitumor agent.

Production aflastatin A from streptomyces sp., a pharmaceutical

The present invention provides a cellulose solution prepared by dissolving a cellulose which has not previously been subject to explosive disruption at atmospheric pressures in an aqueous alkali solution which can be shaped into a fiber, film or other article or applied to the surface or treatment of other materials by coating, dipping, or other suitable methods.

Alkaline method for dissolving cellulose

New compound, designated as leucanicidin, is now provided and is useful as insecticide. Leucanicidin is fermentatively produced by a microorganism Streptomyces halstedii No. 3002-14, (FEKM BP-493).

Process for producing leucanicidin

A method of producing novel macrolides of the formula ##STR1## wherein R means ##STR2## in which n stands for an integer of 0-2 and m denotes an integer of 0 or 1, and R' denotes a methyl or ethyl group using Streptomyces hygroscopicus is described.

The production of KSB-1939 macrolides using STR eptomyces hygroscopicus

Described are KSB-1939 compounds represented by the following general formula (I): ##STR1## wherein R means ##STR2## in which n stands for an integer of 0-2 and m denotes an integer of 0 or 1, and R' denotes a methyl or ethyl group. A production process of the KSB-1939 compounds and pesticidal agents comprising, as an effective ingredient, one of the KSB-1939 compounds are also described.

Antibiotic KSB-1939 compounds as well as pesticidal agents containing

New compound, designated as leucanicidin, is now provided and is useful as insecticide. Leucanicidin is fermentatively produced by a microorganism Streptomyces halstedii No. 3002-14 (identifiable as FERM BP-493).

Leucanicidin

A plant growth regulator comprising, as its active component, one or more compounds selected from the group consisting of [+]-hexylitaconic acid, and the dihydro derivative and lower alkyl monoesters thereof is effective for growth regulation of plants.
