Development of efficient screening method coupled with cell functionality evaluation is highly needed in contemporary microbiology. The presented novel concept and fast non-destructive method brings in to play the water spectral pattern of the solution as a molecular fingerprint of the cell culture system. To elucidate the concept, NIR spectroscopy with Aquaphotomics were applied to monitor the...

Two rapid vibrational spectroscopic approaches (diffuse reflectance-absorbance Fourier transform infrared [FT-IR] and dispersive Raman spectroscopy), and one mass spectrometric method based on in vacuo Curie-point pyrolysis (PyMS), were investigated in this study. A diverse range of unprocessed, industrial fed-batch fermentation broths containing the fungus Gibberella fujikuroi producing the na...

The physiological and biochemical processes of Aspergillus flavus (A. flavus) are complex. Monitoring the metabolic evolution products during growth A. is critical to overall understanding fungal aflatoxin production detection mechanism. dynamic process B1 (AFB1) accumulation in culture media was investigated with a visible/near-infrared hyperspectral imaging (Vis/NIR HSI) system range 400 1000...

Leaf area index (LAI) is an important essential biodiversity variable due to its role in many terrestrial ecosystem processes such as evapotranspiration, energy balance, and gas exchanges as well as plant growth potential. A novel approach presented here is the retrieval of LAI using thermal infrared (8–14 μm, TIR) measurements. Here, we evaluate LAI retrieval using TIR hyperspectral data. Cano...

We study bias of predictors when a multivariate calibration procedure has been applied to relate a scalar y (concentration of an analyte, say) to a vector x (spectral intensities, say). The model for data is assumed to be of latent factor regression type, with multiple regression models and errors-in-variables models as special cases. The calibration procedures explicitly studied are OLSR, PLSR...

Aboveground biomass (AGB) is an important indicator for crop-growth monitoring and yield prediction, accurate of AGB beneficial to agricultural fertilization management optimization planting patterns. Imaging spectrometer sensors mounted on unmanned aerial vehicle (UAV) remote-sensing platforms have become technical method because the convenient, rapidly collects data provides image with high s...

Abstract Detailed knowledge of a soil’s lime requirement (LR) is prerequisite for demand-based fertilization to achieve the optimum soil pH and thus sustainably increasing fertility crop yields. LR can be directly determined by base neutralizing capacity (BNC) obtained soil-base titration. For site-specific acidity management, detailed information on within-field variation BNC required. However...

The purpose of this paper was to explore the utility of an electronic nose to detect the quality of litchi fruit stored in different environments. In this study, a PEN3 electronic nose was adopted to test the storage time and hardness of litchi that were stored in three different types of environment (room temperature, refrigerator and controlled-atmosphere). After acquiring data about the hard...
