Some factors affecting the process of photoinduced hydroxylaminolysis in different bacteriorhodopsin-based media.

This review presents the results of studies concerning some factors that affect the process of photoinduced hydroxylaminolysis (PHA) in bacteriorhodopsin (BR) and different BR-based media. We consider the peculiar properties of the PHA reaction in water suspensions of BR and BR-based media depending on variation in PHA ingredients, and in particular the use of O-substituted hydroxylamines instead of hydroxylamine hydrochloride. In addition, we discuss how such factors as preliminary ultra-sonication affect the reaction of PHA in the course of BR bleaching and following the reconstitution of bacterioopsin. All the results are considered from the viewpoint of improving the performance of BR-based media as photosensitive materials for the processing and storage of optical information.
