Abstract

Physically crosslinked PVA‐hydrogel microparticles are utilized for encapsulation of E. coli and M. luteus. The bacteria survive dry storage or treatment with bacteria‐hostile organic solvents significantly better than unprotected bacteria as proven by culture‐test experiments. The bacteria‐protecting PVA microparticles are available for standard polymer‐solution‐processing techniques, as exemplarily shown by co‐electrospinning of living bacteria encapsulated in dry PVA‐hydrogel microparticles together with PVB‐, PLLA‐, and PCL‐form organic solvents. magnified image
