*2.2.2 Analysis of biomass yield results*

**Table 6** shows the statistical treatment of the biomass production in the experimental tests performed.

*Ethanol production in the 12 experimental tests of the alcoholic fermentation process.*

In **Table 6**, showing the inter-subject effects, a significant value of 0.000 ˂ 0.05 is observed. Therefore, Ha is accepted. This value indicates that there is a significant difference between the groups (Test and time).

In **Figure 7** of estimated marginal means, it is shown that test 8 has the highest biomass yield.
