However, in outdoor cultivations, light availability, besides being influenced by total irradiance, is also determined by reactor configuration (vertical or horizontal) and design.
However, in up-scale or large volume cultivation, mean light intensity is a better indication of light condition; light intensity at the illumination surface, IS and opposite surface, BS (end of light path) need to be considered (Ogbonna and Tanaka 2000).
This classification hints to a function of phlp1 also upon prolonged cultivation in light, i. e. under constant conditions of growth on cellulose in light or darkness.
Thus, all levels of fatty acid contents detected at 18 days were higher than that detected at 14 days of cultivation under light intensity of 220 μmol/m2s.
The objective of this study was to quantify the effect of long-term no-till cultivation with light grazing on soil quality, land productivity, and resource use efficiency.
In another report, the highest biomass (5.03 g/L), TFA (24.9% DCW) and DHA contents (82.8 mg/g) of Crypthecodinium sp. SUN were achieved at 96 h of cultivation under light conditions (Sun et al. 2017).
However, cultivation under light intensity of 220 μmol/m2s, both TFA and ARA volumetric contents were rather low due to low cellular contents (Table 1) in spite of the high growth rate (Fig. 5).
However, due to higher growth rates (Fig. 5), cultivation at light intensity of 220 μmol/m2s resulted in higher yield of TFA (ca. 219.04 mg/L, Fig. 6c) than that at 110 μmol/m2s.
This regulatory impact differs between cultivation in light or darkness.
In Aspergillus ornatus, glucose uptake (but not lysine uptake) is significantly decreased upon cultivation in light.
