This book provides definitive methods to perform stable isotope probing (SIP) experiments, covering a wide spectrum of stable isotope techniques used in microbial ecology, such as methods to target and analyze labeled DNA, rRNA, mRNA, protein, and PLFA. Protocols to study stable isotope fractionation by microbial pathways, the analysis of labeled communities with Raman microscopy, Chip-SIM, as well as quantitative SIP (qSIP) and high-resolution SIP (HR-SIP) are also featured. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their...
