Expression of glycosidase activities during germination of Dictyostelium discoideum spores.

abstract：:Sulfate-utilizing revertants of a cysteine auxotroph of Salmonella pullorum have been found that cause an accumulation in growth medium of a sulfur compound more oxidized than sulfide. The sulfur compound was presumptively identified as sulfite by the formation of a colored complex in the presence of basic fuchsin and...
