The metabolism of carbohydrates by extremely halophilic bacteria: identification of galactonic acid as a product of galactose metabolism.

abstract：:The addition of various concentrations of monensin (1,5, and 10 micrograms/mL) to the culture medium inhibits the fungal growth and perturbs exopolysaccharides secretion, provoking a decrease of production in Botrytis cinerea and an increase in Sclerotium rolfsii. The ionophore induces also modifications in both polym...
