Abstract

Method for production and regeneration of Acetobacter pasterianus protoplasts is described. The protoplasts were obtained by treatment of cells with lysozyme in protoplast buffer at pH 8.0 with different osmotic stabilizers. The protoplasts were regenerated on Acetobacter medium with various osmotic stabilizers. Maximum protoplast formation was obtained in protoplast buffer with NaCl (0.5M) as an osmotic stabilizer and lysozyme (0.5mg/ml). Addition of mutanolysin did not show enhancement in protoplast formation. Maximum protoplast regeneration was obtained on Acetobacter medium with NaCl (0.5M) as an osmotic stabilizer. This is, to our knowledge, the first report on protoplast formation and efficient regeneration in case of Acetobacter pasteurianus.
