“…Advances in the 1990s were favored by the development of interferometric IR spectroscopy and Fourier transform (FT) techniques. The reference work of Helm and colleagues (14) prompted a large amount of research, reviewed by Mariey and colleagues (26). Since 2001, more groups and genera have been studied: Lactobacillus (3,36,37), Carnobacterium (21), Bacillus (1), Brucella (27), Acinetobacter (52), yeasts (20,41), enterococci (7,10,19), coryneforms (24,34), and actinomycetes (54).…”
