[Community structure and diversity formation of fermentation fungi in traditional Shaoxing Huangjiu].

To reveal the formation mechanism of fungal community and diversity during the production of Shaoxing Huangjiu, we examined fungal communities in the samples of Linfanjiumu, Maiqu and fermentation mash based on Illumina MiSeq PE300 high-throughput sequencing platform. A total of 136000, 215283, 166150, and 143624 sequences were obtained from the samples of Linfanjiumu, Maiqu, initial mash and mature mash, respectively. After clustering, 32, 133, 107 and 84 OUT (operational taxonomic units) were obtained, respectively.

A Series Three-Dimensional LnCr (Ln = Gd, Tb, Er) Heterometallic Cluster-Based Coordination Polymers Containing Interesting Nanotubes Exhibiting High Magnetic Entropy.

A series of novel 3D 3d-4f heterometallic cluster-based coordination polymers, [LnCr(μ-O)(μ-O)(NA)(HO)]·HO (Ln = , , ; HNA nicotinic acid; = 13 (), 11.33 (), 15 ()), have been successfully synthesized by hydrothermal method using nicotinic acid as bridging ligand. The single-crystal X-ray diffraction (SCXRD) analysis indicated that the basic unit of LnCr shows a butterfly-shaped structure.

Prediction of enological parameters and discrimination of rice wine age using least-squares support vector machines and near infrared spectroscopy.

The use of least-squares support vector machines (LS-SVM) combined with near-infrared (NIR) spectra for prediction of enological parameters and discrimination of rice wine age is proposed. The scores of the first ten principal components (PCs) derived from PC analysis (PCA) and radial basis function (RBF) were used as input feature subset and kernel function of LS-SVM models, respectively. The optimal parameters, the relative weight of the regression error gamma and the kernel parameter sigma 2, were found from grid search and leave-one-out cross-validation.
