Example: "The study indicated a reduction in viable options for sustainable energy sources."
Alternatives: "a decrease in viable" or "a decline in viable".
The correlation deviated as a primary tumor grew due to a reduction in viable tumor fraction.
The reduction in fertility can result from impaired chromosomal pairing in meiosis, or from crossing-over between heterologous chromosomal blocks and a reduction in viable gametes.
Under these conditions, a reduction in viable count of 105 106-fold was achieved within 5–105 106-foldhigher irradiation energy levels up to 13 mwasm2 were necessachieved
The lowering of the intracellular pH and accumulation of anions disrupts metabolic processes crucial for the survival of the probiotic, leading to a reduction in viable cell counts and shortening the shelf life of the product (Wang et al. 2014).
By contrast, S. enterica serovar Enteritidis and E. coli O157 H7 showed a reduction in viable cells number after 8 h exposure, and the growth inhibition was determined by counting the numbers of CFUs for the bacteria (Fig. 4A: e, f).
For carboplatin treatment of SK-N-BE(2) cells a reduction in viable cell amount by 50% was not obtained within the concentration range used.
During this process, islets are exposed to a number of insults including ischemia, oxidative stress and cytokine injury that may result in cellular damage and functional impairment, which ultimately leads to a reduction in the viable islet mass recovered.
Cytotoxic assay revealed a 50%% reduction in viable cells at a concentration of 189.9 μg/mL.
A lower exposure time may be required to achieve a 6 log10 reduction in viable virus as Adenovirus is likely to become non-viable before DNA becomes non-detectable by PCR.
The reason why we applied formic acid to the drier forage was to determine whether this treatment could exert an acidic chock on the listeria and cause a quick reduction in viable counts.
In this study differences in the survival of Salmonella between acid treated feed materials and controls and increased with time, indicating that the effects observed were not an artefact of the detection method, but reflected a true reduction in viable Salmonella cells.
