This study reports for the first time on the thermodynamics of microbial cathodes for nitrate and nitrite reductions using microbial microcosms isolated from a running denitrifying BES.
A microbial reduction model has been developed using the PEPT data, based on construction of a fractional time density as a function of distance from the UV source.
Iron III) in goethite (formed from schwertmannie transformation) was also reduced and likely proceeded via direct microbial reduction or via electron shuttling using the humic acids in the incubating water derived from pasture grass.
The effect of HP treatment and potassium lactate on microbial reduction was assessed in minced meat, using a full factorial design with three high pressure treatments (200, 350 and 500 MPa), three holding times (2, 8 and 14 min) and two potassium lactate concentrations (0 or 1.8% w/w).
Latanoprost with 0.02% BAK exhibited more effective microbial protection than travoprost with sofZia using rates of microbial reduction, time to no recovery for all challenges and evaluation against EP-A criteria as measures.
Laboratory denitrifying bioreactors, which use an organic carbon (C) rich media to enhance microbial reduction of nitrate (NO3−) to nitrogen (N) gases, are used worldwide to protect surface and groundwater.
The study found out that the treatments that used a commercial scourer in the cleaning had significantly (P < 0.05) less microbial reduction as compared to treatments that did not use the commercial scourer for the TVC and TCC but did not differ significantly (P > 0.05) for the reduction of the LAB.
The hydrodynamic performance of a Surepure Turbulator™ used as an ultraviolet (UV) light source to give microbial reduction in turbid food fluids such as milk has been determined using Particle Image Velocimetry and Positron Emission Particle Tracking (PEPT).
However on plastic jerry cans, use of the commercial scourer had a least microbial reduction of TVC, TCC and LAB when compared to where it was not used.
Microbial reduction and deposition of gold nanoparticles was achieved at 25 °C over the pH range 2.0 7.0 using the mesophilic bacterium Shewanella algae in the presence of H2 as the electron donor.
