Chromatographic Profiles of Ethyl Acetate Extracts Produced by Bacillus sp. Collected from the Mangroves in the Brazilian Northeast

The genus Bacillus is Gram-positive, anaerobic or aerobic facultative bacteria, often described to be associated with the mangrove rhizosphere. Secondary products of their metabolism, coming from places affected by pollution and environmental stresses, such as mangroves, have been attracting interest from the biotechnological point of view. In view of this scenario, this work analyzed the ethyl acetate extracts of the cultured Bacillus species, previously isolated from mangroves located in the state of Sergipe, Brazil. Chromatographic profiles of seven bacterial isolates collected from two different mangroves were analyzed using gas chromatography/mass spectrometry (GC-MS) and many important compounds of biotechnological interests, mainly those derived from azo-aromatic compounds such as pyrazines, pyrrolo-pyrazines, and piperazinediones, were detected. This study is one of the first, in our knowledge, prospecting volatile or semi volatile organic compounds from ethyl acetate extracts produced by bacteria isolated from the mangroves, and intents to increase the interest in this coastal ecosystem as a source of compounds with biotechnological applications.
