Two thiomarinol derivatives, which have antibacterial and anti-mycoplasmal properties, are obtainable from microorganisms of the genus Alteromonas and are named 'thiomarinol B' and 'thiomarinol C'. Thiomarinol B can also be prepared by the oxidation of thiomarinol.

Thiomarinol compounds

A new compound, named Substance No. 51262, may be produced by cultivating a suitable microorganism of the genus Streptomyces, especially the new strain SANK 63584 (FERM BP-958). Said compound has herbicidal and growth retardant properties. Said compound has the following structural formula: ##STR1##

Process for the production of an imidazoledione compound by a strain of

Novel compounds, called chloropolysporins B and C, and salts thereof have antibiotic properties and would appear to be members of the class of glycopeptide antibiotics containing chlorine. They may be produced by cultivating a suitable strain of microorganism of the genus Micropolyspora, especially Micropolyspora sp. SANK 60983 (FERM BP-538). They may be combined with conventional pharmaceutically acceptable carriers or diluents for therapeutic use or incorporated into edible excipients, such as feed or water, for use as a growth-promoting agent, especially for farm animals.

Mycoplanecin derivatives and their preparation

A novel antibiotic substance, named 'Mycoplanecin', of presently unknown structural formula, is produced by cultivating a Mycoplanecin-producing microorganism of the genus Actinoplanes, especially the Actinoplanes nov. sp. Strain No. 41042, NRRL No. 11462.

Antibiotic substance

Antibiotic substance named 'Pholipomycin' which is useful as a growth promoting agent for domestic animals, poultries and the like and produced by the cultivation of a new microorganism, Streptomyces lividoclavatus strain No. 3176, NRRL 8022.
