Statistical analysis of the obtained quantitative data was carried out by using Student’s t-test.
According to the data, the activity of polyphenol oxidasedepends nonlinear on the concentration of MWCNTs in growth medium, and reaches a maximum at 10 mg/l content of MWCNTs.
Reduction in the activity of peroxidase enzyme with increasing concentration of MWCNTs was observed (Fig. 4).
The acquired data correlates with the results of other researches [15, 21].

The water loss data and microstructure of these samples are of primary interest.
This agrees with pore distribution obtained from mercury infiltration porosimetry data, not included in this manuscript.
Mass loss data indicates that CAP90 lost the largest amount of water which increases the likelihood of void formation.

%Al, observed the contrary, that the size of the microstructure promoted the reduction of resistance to corrosion.
These data allowed to obtain the tip growth rate and the cooling rate.
By means of an automatic data acquisition system, the polarization curves are expressed as a function of the logarithm of current density and electrode potential, from which the corrosion current density (Icorr.) and corrosion potential (Ecorr.) values are obtained using the Tafel extrapolation method.
