Special Issue Information

Dear Colleagues,

In recent decades, increasing attention has been paid to the application of fermentation in the agricultural and food industry. Fermentation is one of the most traditional, but still prevalent, bio-processing approaches in the agricultural and food industry and is a low-cost, high efficiency, eco-friendly and promising process technology that has great potential to improve the properties of agricultural products (e.g., flavor and health effects). Agro-industrial raw materials (legumes, tea, flower, fruits, vegetables, etc.) can be used as excellent substrates for fermentation to produce flavor and bioactive compounds, which could be used as natural food additives to meet consumer demands. Over the past few years, with the rapid progress in microbial fermentation technologies and in-depth investigation of the modernization of the agricultural and food industry, the microbial fermentation and transformation of agricultural products have gained considerable interest and appear as a promising way to produce flavor and bioactive metabolites. In addition, a large number of agricultural byproducts or wastes are produced worldwide every year, which aggravate the burden of industry production costs and cause serious environmental sustainability issues. The microbial biotransformation of low-cost agricultural residues/byproducts could not only create a high-value-added flavor and/or bioactive compounds but also be beneficial toward waste treatment and environment problems.

In view of the above potential and developments, the journal Agronomy is inviting authors to submit unpublished original contributions, critical review articles, and short communications for consideration in the Special Issue, “Effects of Fermentation on Flavor Compounds and/or Biological Activity in Agricultural Products”. Topics covered in this Special Issue include but are not limited to:

  1. The accumulation of flavor or bioactive compounds using agricultural material by microbial biosynthesis or biotransformation;
  2. Aromatic precursors and fermentation metabolites;
  3. The high-added-value utilization of agricultural products via fermentation;
  4. The improved health benefits of fermented agricultural products;
  5. The microbial production of flavor or bioactive compounds using agro-residues;
  6. The valorization of agro-industrial residues/byproducts by fermentation to produce bioactive compounds, such as antioxidant compounds, bioactive peptides, polysaccharides, etc.

There are a variety of amino acids and polysaccharides contained in Pleurotus eryngii that can improve immunity and prevent cancer in humans. The purpose of this research was to investigate the improved quality hypha of P. eryngii-3, which could shorten the ripening cycle of the hypha and increase economic benefits to industries. In this paper, the quality hypha of P. eryngii-3 was investigated for the DCW, total protein, polysaccharides, laccase activity, and so on. The medium was screened and carbon and nitrogen sources were screened and optimized as 40 g/L of corn flour and soybean meal by P. eryngii-3. Then, the effects of pH, temperature, volume, and rotation speed were investigated, in which the suitable fermentation conditions were, respectively, pH = 6, a temperature of 27 °C, 90 mL of fermentation broth, and a 150 r/min rotation speed. Meanwhile, the transcription levels of Lcc1, Lcc5, Lcc8, and Lcc12 were upregulated by 10.25-, 3.32-, 2.33-, and 6.29-fold, respectively, after the optimization. In addition, the response surface method of the BBD was utilized for further improvements to the DCW by P. eryngii-3, in which the optimized DCW reached 17.2345 ± 0.7845 g/L. Full article
