The phrase "as a function of cultivation time" is correct and usable in written English.
It is typically used in scientific or technical contexts to describe how one variable changes in relation to the duration of cultivation.
Example: "The growth rate of the plants increased significantly as a function of cultivation time."
Alternatives: "in relation to cultivation time" or "depending on cultivation time".
In 2009, Fuchs et al. analysed the dynamic processes involved in the differentiation and functionality of both cell types in the coculture system as a function of cultivation time [ 32].
The DNA content of monolayer cultures as a function of cultivation time was analyzed.
Since it's expression decreases as a function of cultivation time, the data indicate that ESCM must either be actively withdrawing from the cell cycle or undergoing a checkpoint delay in G1.
All the parameters calculated according to Eqs. 1– 7, are expressed as time-averaged functions of cultivation time (i.e. the value at the time point of interest corrected by amount present at time zero and divided by the time from inoculation).
The hypo-phosphorylated or active (inhibitory) form of Rb markedly increased as a function of in vitro cultivation time.
The Fv/Fm of untreated cells as a function of the time of dark cultivation is also shown.
a Cell concentration (cells mL−1) as a function of time (h), for recombinant C. reinhardtii Gluc (strain expressing Gaussia luciferase) cultivations containing: 0.0, 0.1.0,.0, 2.0, 5.0, 10.0, 25.0 and 100.0 µM selenocystamine final concentration in the culture medium, compared to control w1.1 (psbA knockout).
b Cell concentration (cells mL−1) as a function of time (h), for recombinant C. reinhardtii GFP (strain expressing green fluorescent protein) cultivations containing: 0.0, 0.1.0,.0, 2.0, 5.0, 10.0, 25.0 and 100.0 µM selenocystamine final concentration in the culture medium, compared to control w1.1 (psbA knockout).
The volumetric glycerol uptake rates in the glycerol cultivations were estimated by linear regression of the substrate concentration as a function of time, and results are summarised in Table 1.
The temperature in the shake flask was continuously monitored as a function of time and samples were taken at predefined temperatures in the range from 30 to 62°C over a total time span of 12 minutes for all cultivation-dependent and independent analyses described throughout this study.
