词汇 biocatalyst
释义

Definition of biocatalyst in US English:

biocatalyst

noun ˌbīōˈkadələstˌbaɪoʊˈkædələstˌbaɪoʊˈkædələst
  • A substance, such as an enzyme or hormone, that initiates or increases the rate of a chemical reaction.

    Example sentencesExamples
    • Functioning as biocatalysts, enzymes increase and control the rate of chemical reactions.
    • The simple end result is that considerably more enzyme per unit volume of fermentation liquor is produced; biocatalyst activity is effectively increased several hundred times.
    • For example, by manipulating the microenvironment of an enzyme, through solvent or biocatalyst engineering, it has become possible to modulate enzyme activity, tailor biocatalyst selectivity, and alter enzyme stability.
    • Chapter 22 provides an industrial perspective on the use of biocatalysts in biotechnology processes.
    • Critical to the success of this technology is a bio-transformation process step, using an enzyme biocatalyst.
    • Thus, there must be an efficient transport system to shuttle them across the various layers of membrane and cell wall, and the outer cell wall must also possess a biocatalyst that takes care of the mineral's reduction.
    • Decontamination of soil and water via efficient biocatalysts is a promising cost-effective remediation strategy.
    • He wanted to create a biocatalyst, using enzymes to try and find applications in the pharmaceutical industry.
    • The alternative synthesis uses a biocatalyst, the yeast Zygosaccharomyces rouxii, and a novel three phase reaction system.
    • But Rath's most monumental achievement is the discovery of cellular medicine, the study of ‘the role of micronutrients as biocatalysts in a multitude of metabolic reactions at the cellular level.’
    • For decades, there were only two types of catalyst - metals and enzymes - but since 1986 two new classes of biocatalyst have emerged along with the enzymes, ribozymes, and catalytic antibodies.

Derivatives

  • biocatalytic

  • adjectiveˌbīōˌkatlˈitik
    • Organic solvents have been widely used as solvents in biocatalytic reactions due to all known advantages that such media offer.
      Example sentencesExamples
      • In addition, our group is currently developing combined chemical / biocatalytic systems in novel solvents, allowing the use of reactive intermediates as substrates for enzymatic catalysis.
      • Enzymes produced by extremophiles (bacteria and fungi living in harsh conditions) are also highly exploitable in the biocatalytic industry.
