7] cfu/g of microorganism colonies have grown in each biofilter cassette.A nearly ten-fold increase in AFLP citations in the scientific literature in the past five years is an indication of its wide acceptance as a useful DNA fingerprinting technique in the plant science area and its growing use for identifying microorganisms in other areas.It's much easier to do experimental work on such behavior in microorganisms than in traditionally studied animals.Most microorganisms grow in structured biofilms rather than individually in suspensions and while in this environment may display altered phenotypes (2).Another interest that has developed is the whole area of pollution and environmental damage, also allied to microorganisms.If the concentration of fluoroquinolone attained at the bacterial DNA targets is high enough to activate the SOS system for a duration that exceeds the capability of the particular microorganism to repair its DNA damage and replicate, the microorganism dies.A group of researchers studying methane-bearing sediments collected off the coast of Oregon has discovered aggregates of two fundamentally different microorganisms, which appear to be collaborating to consume the gas.Phytera plans to apply its ENRICH techniques to both the plant cell culture and marine microorganism areas.Microorganisms commonly attach to living and nonliving surfaces, including those of indwelling medical devices, and form biofilms made up of extracellular polymers.In Canada, biopesticidal uses of microorganisms are regulated by the Pest Management Regulatory Agency of Health Canada, under the Pest Control Products Act (PCPA); bioremedial uses are regulated by Environment Canada under the Canadian Environmental Protection Act (CEPA) (3).We might never find where it came from, " says Gellert, noting that the responsible microorganism might be extinct.Michael Treble, President of the Ibis Biosciences division and Vice President of Isis Pharmaceuticals, commented, "We're excited about the European introduction of the Ibis T5000 biosensor system, which has the potential to revolutionize infectious microorganism detection.
