Molecular view by Fourier transform infrared spectroscopy of the relationship between lactocin 705 and membranes: Speculations on antimicrobial mechanism
Article Abstract:
Fourier transform infrared spectroscopy is used to examine the interactions of two peptides, lactocin 705 [alpha] and lactocin 705 [beta], with dipalmitoylphosphatidylcholine liposomal membranes. The results have shown that component Lac705[alpha] might induce the dehydration of the bilayer interfacial region and the Lac 705[beta] peptide might insert in the hydrophobic region of the membrane where the peptide has adequate conditions to achieve the oligomerization.

Investigating microbial (micro)colony heterogeneity by vibrational spectroscopy.
Article Abstract:
Researchers should use bacterial colonies that are six hours old or less when determining the spectral properties of the bacteria. After six hours, the spectra become very heterogeneous. Fourier transform infrared and Raman microspectroscopy are being tested as a rapid technique for identifying microorganisms in body fluids.

Quantitative determination of the biodegradable polymer poly(beta-hydroxybutyrate) in a recombinant Escherichia coli strain by use of mid-infrared spectroscopy and multivariate statistics
Article Abstract:
Fourier transform infrared (FTIR) spectroscopy can be used to measure the amount of poly(beta-hydroxybutyrate in bacterial cells. It requires no solvent, minimal sample preparation, and can be done quickly.
