The application of microbial extracellular polymers began in the 1960s
, and since then there has been a remarkable increase in their commerc
ial use. They are used in the food, textile, pharmaceutical, agricultu
ral, paint and petroleum industries. Volcaniella eurihalina, a moderat
ely halophilic eubacterium, produces an extracellular polysaccharide w
hose physical and chemical properties could be of interest for various
industrial applications. The aim of this investigation is to analyze
the different environmental parameters which influence the production
of polysaccharide, and to study its chemical composition and the theol
ogical properties of its solutions.
