Simplified X-ray film method for detection of bacterial volatilization of mercury chloride by Escherichia coli.

abstract：:Symbioses with gut microorganisms provides a means by which terrestrial herbivores are able to obtain energy. These microorganisms ferment cell wall materials of plants to short-chain fatty acids (SCFA), which are then absorbed and used by the host animal. Many marine herbivorous fishes contain SCFA (predominantly ace...
