Characterizing metabolic stress-induced phenotypes of Synechocystis PCC6803 with Raman spectroscopy.

abstract：:The evolution of the modern human (Homo sapiens) cranium is characterized by a reduction in the size of the feeding system, including reductions in the size of the facial skeleton, postcanine teeth, and the muscles involved in biting and chewing. The conventional view hypothesizes that gracilization of the human feedi...
