GC-MS, FTIR and Raman spectroscopic analysis of fatty acids of Pistacia vera (Greek variety “Aegina”) oils from two consecutive harvest periods and chemometric differentiation of oils quality

Structural equation model was used to evaluate the effects of soil chemical environment, fertility and enzyme activity on eucalyptus biomass

“…We believe that a systematic approach should be adopted to evaluate and establish the interaction pathways between soil fertility, organic fractions and enzyme activities, and to evaluate the effects of these factors on plant growth in a comprehensive manner. Fourier transform infrared (FTIR) spectroscopy can determine the quantity and chemical structural composition by measuring infrared radiation (400–4000 cm −1 ) of organic functional groups in soils [ 26 ]. In this study, we characterized the organic chemical structure of eucalyptus plantation soils of different successive planting generations using FTIR [ 27 ].…”

Fourier Transform Infrared (FTIR) Spectroscopic Study of Biofilms Formed by the Rhizobacterium Azospirillum baldaniorum Sp245: Aspects of Methodology and Matrix Composition

“…The diverse field of microbiology has been progressively developing over the last decades, largely owing to the steadily growing applications of a range of modern molecular spectroscopy techniques that provide molecular-level information on complicated microbiological objects and allow for successfully solving various bioanalytical problems, often in situ or in vivo (see, e.g., [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ]). We would like to emphasize the informativity of very relevant vibrational spectroscopic techniques, including various modifications of infrared (conventional absorption [ 2 , 7 , 11 , 16 ], diffuse reflectance [ 3 , 6 ], attenuated total reflectance (ATR) [ 5 , 17 ] and surface-enhanced absorption [ 15 ] modes; 2D infrared [ 8 ]) and Raman [ 1 , 2 , 13 ] spectroscopies, as well as their combinations [ 4 , 14 ]; vibrational circular dichroism [ 12 ], optical activity [ 9 ], etc. Of special notice are microbiological applications of Mössbauer spectroscopy, in both transmission and emission variants [ 2 , 10 ].…”

“…Among these techniques, Fourier transform infrared (FTIR) spectroscopy, which has already become a routine tool in material science, yet could not be regarded as routine in the life sciences [ 4 , 6 , 7 ], and particularly in microbiology [ 3 , 5 , 8 , 13 , 14 , 15 , 17 , 18 , 19 ]. This situation can in part be explained by the intrinsically sophisticated compositions and structures of diverse microbiological objects, making the processes of sample treatment or preparation for spectroscopic studies, together with treatment of the spectroscopic data and interpreting the results, a challenging task [ 19 ].…”

Accumulation Pattern of Flavonoids during Fruit Development of Lonicera maackii Determined by Metabolomics

“…Metabolomics uses metabolic information to reveal endogenous metabolic changes in plant systems [25,26]. A variety of tools are used for metabolomics analysis including high-performance liquid chromatography (HPLC) [27], liquid chromatography-tandem mass spectrometry (LC-MS) [28], gas chromatography-tandem mass spectrometry (GC-MS) [29], mass spectrometry (MSn) [30], thin layer chromatography (TLC)-UV spectrophotometry [31], capillary electrophoresis (CE) [32], electrochemistry [33], and NMRspectrometry [34]. Currently, ultra-high performance liquid chromatography-mass spectrometry (UPLC-MS/MS) is a leading technology for detecting plant-based metabolites and is often used as a guide for the separation and identification of phytochemicals [35].…”
