Abstract: A biosynthetic method for producing glucosamine and N-acetylglucosamine is disclosed. Such a method includes the fermentation of a genetically modified microorganism to produce glucosamine and/or N-acetylglucosamine. Also disclosed are genetically modified microorganisms that are useful for producing glucosamine and N-acetylglucosamine. In addition, methods of recovering N-acetylglucosamine that has been produced by a fermentation process, including methods that result in N-acetylglucosamine of high purity, are described. Also disclosed is a method to produce glucosamine from N-acetylglucosamine.

Abstract: Devices for the detection of small quantities either of divalent inorganic mercury ion (Hg.sup.2+) or of both Hg.sup.2+ and monomethyl mercury in water are disclosed. These devices comprises a bioluminescence detecting means and a bioluminescent biosensory microorganism cells, that emit significant light only when exposed to either to Hg.sup.2+ or to Hg.sup.2+ or momomethyl mercury. Plasmid cassettes and host microorganisms containing such cassettes are also disclosed The plasmid cassettes comprises a lux gene operon complex from Xenorhabdus luminescens. The lux operon complex comprises luxC, luxD, luxA, luxB, and luxE genes but is free of (1) a promoter for the complex and (2) an inducible regulatory gene for the complex.
