Liposome‐protoplast interactions

A large number of different biological compounds can be encapsulated in liposomes and then delivered into the cytoplasm of cells by fusing these lipid vesicles with protoplasts. The essential properties of protoplasts and liposomes are briefly described. Examples of two liposome-protoplast interactions, involving the delivery of intermediates of antibiotic biosynthesis into fungi and DNA into Streptomyces are discussed. References are made to other experiments suggesting that liposomes may be useful in many areas of biotechnology.
