Toxic-metabolite-producing bacteria and fungus in an indoor environment

Article Abstract:

Researchers isolated bacteria and mold from a water-damaged house that produced toxic substances that affected cell mitochondria. The microorganisms included Bacillus simplex, Streptomyces, Nocardiopsis, Trichoderma harzianum and Bacillus pumilus.

The mitochondrial toxin produced by Streptomyces griseus strains isolated from an indoor environment is valinomycin

Article Abstract:

A study was conducted to characterize Streptomyces griseus strains emitting a toxin in indoor air and in indoor dust. An Andersen sampler and tryptic soy agar were utilized to collect actinomycetes while electrospray mass spectra were determined with a model API300 triple quadrupole mass spectrometer. Experimental results indicated that S. griseus isolates determined from dust and air in water-damaged buildings generated valinomycin.

Toxigenic strains of Bacillus licheniformis related to food poisoning

Article Abstract:

Research was conducted to examine the genetic diversity of toxin producing Bacillus licheniformis implicated in food poisoning. Results show that more than one bacterial types can be isolated from each of the three different food sources.
