Abstract: Methods and systems for the enhancement of bioproduct process yields. The present invention provides systems and methods for improvement of the carbon conversion efficiency by yeast of an organic substrate such as a fermentable sugar to a fermentation product such as ethanol. Exemplary yield-increasing/growth-inhibitory compounds include tyrosol (TyrOH), 2-phenylethanol (PheOH), and tryptophol (TrpOH). Immobilization of the yeast, such as in a porous bead or pellet, can further increase yield. Exemplary immobilization included immobilization in calcium alginate beads. The system and methods taught herein demonstrate that product yield such as ethanol yield can be improved by adding yeast yield-increasing/growth-inhibitory molecules to reduce cell growth of yeast species, such as S. cerevisiae, suggesting a strategy to improve the yield of ethanol and other yeast fermentation products by manipulating native biological control systems.

Abstract: A distal tip, and associated method of producing, of a biosensor ion sensing transducer for use in detecting an analyte comprising an halogenated organic compound in an environment such as soil or an aqueous environment. Features include: a biocomponent comprising at least one enzyme for carrying out a dehalogenation of the compound; the biocomponent is immobilized to a surface of the tip; a treatment of the biocomponent for maintaining a period of enzymatic efficacy; and the biocomponent stabilized by means preferably selected from the group consisting of crosslinking a surface of the immobilized biocomponent, crosslinking a polymer layer to the biocomponent, adding a gel-hardening agent to the biocomponent, adding a stabilizing agent to the biocomponent, and modifying a component of the immobilizing means. Immobilization can be carried out by: (a) entrapment within a hydrogel; (b) entrapment within a polymeric network; (c) (micro)encapsulation; (d) covalent-bonding; and (e) adsorption.
