Among these, bacteria belonging to the genus Alteromonas, and precisely to the species A. macleodii, were identifi ed as being able to produce large amounts of biologically active exopolysaccharides (EPS). A close investigation of some of these biopolymers revealed that they could be of powerful value in the cosmetic industry by providing a new way to protect the skin from environmental injuries. The best example is a polysaccharide produced by A. macleodii, strain HYD657a (EPS657) that is the sole bioactive polymer in a described Alteromonas ferment extract formulationb (SEPS657). The present review will focus on this ferment extract with particular emphasis on its properties as exemplifi ed by a number of laboratory and clinical studies. A separate article on page 26 discusses the scheme of events that led to its discovery.
