Abstract

The effect of nutrient liquids with the bacteria Acinetobactre johnsii str. J221 and Pseudomonas aeruginosa str. G.d. on the rheological properties of porcelain slip is studied. The surface activity of the nutrient liquid promotes a reduction of the fluidity and thixotropic hardening of porcelain slip. The mass increase of the casting upon pouring is due to the hydrophobization of the surface of the slip particles. The thickening of the porcelain slip is interrelated with the change in the redox state of the medium from weakly to strongly basic, favorable for the development of an aborigennic community of anaerobic microorganisms.
