Summary:Monitoring the growth status of microalgae is very important. Traditional techniques for the detection and evaluation of life information during the growth of microalgae are tedious, laborious, destructive and time-consuming. Objective quality assessments and efficacious safety surveillance for microalgal growth information are inseparable from innovative techniques. This review focuses on the applications of several valuable spectroscopic techniques, including visible and near-infrared spectroscopy, Raman spectroscopy, Fourier Transform Infrared (FTIR) spectroscopy and fluorescence spectroscopy, for the rapid and nondestructive detection of microalgae growth information, such as pigment content, oil content, biomass content and identification of algae species. The fundamentals of Spectroscopic Techniques are presented and discussed. Then, we illustrate the most typically and commonly used chemometric analysis, such as spectral preprocessing and modeling methods. Moreover, the advantages and disadvantages of these technologies are discussed, and the applications of these technologies are summarized.
