This is caused by a counterbalanced effect of viscosity decreasing (increase mobility) and decreasing relative permittivity (slightly decrease mobility) of the medium following Sinton et al. [ 12].
Independent of the presence of ferric (oxyhydr oxides, yeast growth in the presence of TNT occurred with a pH decrease of the synthetic medium from an initial pH of 6.0 to below 3.0 because of production of organic acids (Additional file 1: Table S1, Supporting Information, SI).
A cleavage reaction of the chemical bond between NPs and GS, effected by the contact of material with a solution presenting an acidic pH (in the case of infection, there is a decrease of the physiological medium pH), induces controlled release of the bioactive molecule in its native form.
It was shown, for the non-ionic hydrogels, that this deswelling occurs due to the mixing entropy of the linear polymer in the external solution, whereas, for the ionic gels, due to trapping of counterions caused by the decreased polarity of the medium.
The decreasing pH of the medium triggered H2 production.
Dopamine modulates cortical and thalamic glutamatergic inputs to the striatum by acting on D1- and D2-type receptors, increasing or decreasing excitability of the medium spiny neurons, respectively.
The OD and scattered light intensity decreased with decreasing phosphate content of the medium (as could be expected from results of Figure 2).
The excess amount of CO2 may present in the aqueous medium in the form of carbonic acid, which may lead to decrease the pH of the medium below 6 (Fig. 12).
Growth of M. pneumoniae causes decrease of PH of the medium, which is indicated by a color change (from red to yellow) in the indicator.
Protoplasts were recovered after centrifugation (30 min at 8,000 × g) and hypo-osmotic shock was applied in the presence of 10 μg/mL DNase I (Fluka, Buchs, Switzerland) to decrease the viscosity of the medium.
