A destructive sampling process was adopted at five time points for dividing the entire cultivation at intervals of four, five, or six days (for growth periods of 20, 25, or 30 days, resp ., in order to determine pH, electric conductivity, biomass, total phenolics, decolorization, plant seed germination, and enzymes activity.
Additionally, the submerged cultivation process was explained using the optimized cultivation medium.
The cultivation process, however, needs to be repeated until the seed bank is depleted.
President Brian Lade has automated many tasks in his cultivation process.
Table 1 Yield coefficients during the fed-batch process of the yeast cultivations in triplicate Cultivation phase YX/G (gbiomass/gglucose) Batch phase 0.31 ± 0.01 Controlled feeding phase 0.49 ± 0.01 Entire cultivation 0.46 ± 0.02 The values in the table are mean value ± standard deviation The starting time of the controlled feeding phase is shown in Fig. 3d.
Mold, pesticides and other chemicals used in the cultivation process can also bring as yet undetermined negative effects.

Throughout the entire cultivation, A. niger displayed a dispersed morphology.
In all experiments treatment was done for the entire cultivation period starting at DIV 1.
Ideally, the entire process, from cultivation to fuel burning in engines, should favour carbon sequestration, reduce water needs and promote energy efficiency.
