A group from Ecological Security and Protection Key Laboratory of Sichuan Province, Mianyang Normal University, Mianyang, China, etc. has reported Burkholderia gladioli strain KJ-34 exhibiting broad-spectrum antifungal activity.

It was shown that Burkholderia gladioli strain KJ-34 is a potential biocontrol bacterium isolated from the rhizosphere soil of rice and can fight multiple fungal pathogens (i.e. Ustilaginoidea virens, Alternaria solani, Fusarium oxysporum, Phytophthora capsica, Corynespora cassiicola).
Metabolites of this strain exhibiting antifungal activity appeared to be Ac-Yvad-cho, benzoylstaurosporine, TAXOL C, morellin, jubanine B, trichostatin A, thapsigargin, kabiramide B, scopolamine, enniatin B, latrunculin A, rifaximin, rigin, and garcinone C.
We have to be careful that some Burkholderia bacteria are pathogenic. For instance, Burkholderia gladioli BSR3 infects rice, causing bacterial blight, and another rice seed−borne bacterium, B. glumae, causes rice grain rot.
