Plenty of Metabolites produced by Antibiotic-Producing Bacterium

The bacterium Streptomyces chartreusis is an antibiotic-producing bacterium that releases more metabolites into the surrounding medium than scientists assumed based on the analysis of the genome. Many of the substances are likely released to mediate interactions with its environment. They might also include molecules that are of interest as potential pharmaceutical agents.

The researchers analyzed a broad spectrum of the bacterium's metabolic products under various culture conditions. The study is published in the journal Proceedings of the National Academy of Sciences.

Study Finds Source of Toxic Green Algae Blooms

In St. Lucie Estuary, Florida, a massive amount of toxic green slime found that covered parts of the 7-mile-long inlet linked to a coastal river system.  Microcystis aeruginosa – a freshwater blue-green alga that can produce toxins – wreaked havoc on this important ecosystem prompting researchers from Florida Atlantic University's Harbor Branch Oceanographic Institute (HBOIto get to the root of the problem. Results of the study, which uncovered a major source of nutrients driving the harmful algal blooms, stink.
