A dicarboxylic acid compound obtainable by oxidative degradation of pradimicin antibiotics, which are antibiotics consisting of the benzonaphthacene skeleton, a D-amino acid side chain and a sugar chain, for the second saccharide residue of the sugar chain, and use thereof utilizing a specific microorganism binding property thereof are provided. The dicarboxylic acid compound has significantly improved water-solubility compared with the raw material antibiotics, whist maintaining the specific microorganism binding property.

Benzonaphthacene glycoside derivative and use thereof

A disease control agent and a phytoalexin inducing agent, comprising Streptomyces sp. R-5 as an active ingredient are disclosed. Disease-resistant plants may be produced by inoculating plants with the disclosed Streptomyces sp. R-5. The disease control agent and a phytoalexin inducing agent are further useful in that they have low toxicity to humans and cause no environmental contamination.

Plant disease control agent

The present invention relates to a fermentation process for producing BMY-28960 and desxylosyl BMY-28960, and to a novel BMY-28960-producing organism belonging to the genus Actinomadura and designated as strain AB 1236 (ATCC 55208).
