The phrase "activity of cultures" is correct and usable in written English.
It can be used to discuss the various practices, traditions, and interactions that characterize different cultures.
Example: "The activity of cultures throughout history has shaped the way societies evolve and interact with one another."
Alternatives: "cultural practices" or "cultural activities".
Iron cylinder reduced mitochondrial activity of cultures with potency similar to cisplatin, inhibited the cell cycle, and increased cell death by apoptosis.
Electrogenic activity of cultures were then monitored under 24 h illumination cycles under light of the three individual colors for 3 consecutive days for each color.
Fresh medium was replenished every 24 72 h, depending on metabolic activity of cultures.
Perilla oil appeared to attenuate the T-cell-activating activity of culture supernatants in a dose-dependent fashion.
To assess the biological effects of passage through clinically relevant needles on the viability and metabolic activity of culture-expanded, human adipose tissue derived mesenchymal stromal/stem cells (AMSCs).
The MMP activity of culture supernatants was investigated by cleavage of a fluorescent MMP specific substrate.
Azoreductase, laccase, tyrosinase, phenol oxidase, and manganese peroxidase activity of culture supernatant of fungal pellets was carried out.
Fig. 1 The antimicrobial activity of culture supernatants from B. amyloliquefaciens N2-4 and N3-8 isolates against B. pseudomallei.
The total MMP activity of culture supernatants was evaluated using the MMP-substrate Mca-Arg-Pro-Lys-Pro-Tyr-Ala-Nva-Trp-Met-Lys(Dnp -NH2 (Bachem, UK) with a quencher anDnp -NH2ly fluorescent end.
The antimicrobial activity of culture supernatant from N2-4 were decreased by heat, abolished when autoclaved and can be completely destroyed by proteolytic enzymes suggesting that the main active compounds against B. pseudomallei are proteins.
