Cellular damage in dried lactobacillus acidophilus.

摘要: Lactobacillus acidophilus cells surviving freeze drying and vacuum became sensitive to oxgall lysozyme probably from damage the cell wall. The dried also NaCl permeable orthonitrophenol β-galactoside cytoplasmic membrane. Scanning electron microscopy indicated loss of some surface material damaged cells. Transmission (TEM) revealed partial wall membrane material, but these losses seemed have resulted treatments given during fixation for TEM as a consequence that occurred drying. A protein 46-kilodalton molecular weight, is bound by hydrogen bonding, was lost It postulated adversely affects weak bonds cellular macromolecules water.
