Abstract |
Raman spectroscopy is a promising tool for identifying microbial
phenotypes based on single cell Raman spectra reflecting
cellular biochemical biomolecules. Recent studies
using Raman spectroscopy have mainly analyzed phenotypic
changes caused by microbial interactions or stress responses
(e.g., antibiotics) and evaluated the microbial activity or substrate
specificity under a given experimental condition using
stable isotopes. Lack of labelling and the nondestructive pretreatment
and measurement process of Raman spectroscopy
have also aided in the sorting of microbial cells with interesting
phenotypes for subsequently conducting physiology
experiments through cultivation or genome analysis. In this
review, we provide an overview of the principles, advantages,
and status of utilization of Raman spectroscopy for studies
linking microbial phenotypes and functions. We expect Raman
spectroscopy to become a next-generation phenotyping
tool that will greatly contribute in enhancing our understanding
of microbial functions in natural and engineered
systems. |
