The phrase "a decrease in enzyme" is correct and usable in written English.
It can be used in scientific or medical contexts when discussing the reduction of enzyme levels or activity.
Example: "The study revealed a decrease in enzyme activity, which may contribute to the observed symptoms."
Alternatives: "a reduction in enzyme" or "a decline in enzyme levels."
However, immobilization promoted a decrease in enzyme activity for all experiments.
A decrease in enzyme production was noted when the inoculum size increased, which is due to the shortage of nutrients available for the larger biomass and faster growth of the culture (Sathya et al. 2009).
For Aspergillus niger commercial inulinase, a decrease in enzyme activity was observed (residual activity of 39%) using CO2 treatment at 75 bar for 6 h exposure at the highest depressurization rate (200 kg m−3 m−3−1).
A decrease in enzyme activity was observed upon addition of more than 10 mM of divalent cations (results not shown).
IDE activity was decreased in soluble fractions from the brain of AD patients compared to normal control brains [48], which suggests that a decrease in enzyme activity could be responsible for the increased accumulation of pathologic amyloid peptides during AD.
A decrease in enzyme activity in neurons subjected to excitotoxic conditions may activate compensatory mechanisms in surviving neurons since the expression of GAD is regulated by the abundance of GABA by a mechanism independent of the activation of GABA receptors [73], [74].
In contrast, some results observed in rat muscle proteomic analyses were confirmed in human muscle, such as a decrease in enzymes involved in glycolytic metabolism and an increase in proteins involved in cytoprotection (carbonic anhydrase 3) and cytodetoxification (Hsp70) [ 20, 21].
Increasing GA concentration in the solution of Au-NH2 CTAB) Au-NH2 CTABes, a decreasinanoparticlesactivity was observedecreasingases at almost constant enzyme loading (92% to 96%) in 7 h.
These results are in accordance with that of Gancarz et al., 2003 [ 23], who observed that an increase in surface epoxy groups led to an increase in quantity of immobilized enzyme, but a decrease in retained enzyme activity.
28 Similarly, there is a decrease in oxidative enzyme activity in the profits of glycolytic enzymes.
Soil microbial biomass decreased with increasing application of PS-NP, wasch walsolso accompanied by a decrease in most enzyme activities suggesting broad antimicrobial effects of PS-NPs on soil microbiota and enzymes.
