Aerobic granular sludge taken from a sequencing batch reactor at steady state was used in this study. After aerated for 1 and 4 hours at high organic loading rate, the mixed liquid suspended solids (MLSS) concentration of granular sludge increased from 1.16 g/L to 1.48 g/L and 1.56 g/L, respectively, similar to the growth process of floc-like sludge and small granules. The number per milliliter mixed...
Near infrared spectroscopy combined with chemometrics was investigated to determine the total amino acids (TAA) in oilseed rape leaves. The samples in calibration, validation and prediction set were 80, 40 and 30, respectively. Different spectral preprocessing were compared, and three calibration methods were employed including partial least squares (PLS), multiple linear regression (MLR) and least...
A new acetolactate synthase (ALS)-inhibiting herbicide of pyribambenz-propyl (PP) was applied to oilseed rape leaves with different positions. ALS could reflect the growing states of oilseed rape. Visible and near-infrared (Vis/NIR) spectroscopy was investigated for fast and non-destructive determination of ALS in rapeseed leaves. Partial least squares (PLS) analysis was the calibration method with...
Determination of protein structural class is a quite meaningful topic in protein science, because a priori knowledge of a protein structural class can provide useful information about its overall structure. The results of most previous studies used high homologous dataset with four structural classes should not be perceived as reliable, because the sequence homology has very significant impact on...
