Silicon Polyethylene Glycolates and Silicon Glycerolates As Perspective Matrices for Yeast Cell Encapsulation in the Sol-Gel Synthesis

This report presents a comparative analysis of the structures and viability of methylotrophic yeast encapsulated into organosilica matrices of various compositions. The encapsulation of methylotrophic yeast is shown to result in the formation of cell-in-shell structures using biocompatible silicon polyethylene glycol and silicon glycerolate. After the encapsulation, the cells retain an intact membrane and are viable, which is important for their further application in biotechnology, ecology, and medicine.
