Utilization of synthetic microbial community in solid-state fermentation (SMC-SSF) for converting Chinese distiller grains into protein feed
Chinese distiller grains (CDGs) are a primary by-product of the Baijiu production process. This research focused on converting CDGs into high-protein, low-fiber, and non-toxic feed through the synergistic effects of the synthetic microbial community in solid-state fermentation (SMC-SSF) of CDGs. After fermentation promoted by inorganic nitrogen, the protein content indicated 33.32%. Concurrently, crude fiber, ethanol, lactic acid, and acetic acid content were decreased by 20.46%, 64.28%, 64.28%, and 90.96%, respectively. Additionally, zearalenone and aflatoxin B1 content decreased by 9.32% and 63.75%. The organic acid, ethanol, and mycotoxin content in fermented CDGs (FCDGs) complied with the standards of Food and Agriculture Organization (FAO). While the digestibility was enhanced 62.46%, it also showed the effective antimicrobial activity against Escherichia coli and Staphylococcus aureus. This study provides a viable pathway for producing protein feed with enhanced probiotic characteristics.
期刊介绍：
Chemical and Biological Technologies in Agriculture is an international, interdisciplinary, peer-reviewed forum for the advancement and application to all fields of agriculture of modern chemical, biochemical and molecular technologies. The scope of this journal includes chemical and biochemical processes aimed to increase sustainable agricultural and food production, the evaluation of quality and origin of raw primary products and their transformation into foods and chemicals, as well as environmental monitoring and remediation. Of special interest are the effects of chemical and biochemical technologies, also at the nano and supramolecular scale, on the relationships between soil, plants, microorganisms and their environment, with the help of modern bioinformatics. Another special focus is the use of modern bioorganic and biological chemistry to develop new technologies for plant nutrition and bio-stimulation, advancement of biorefineries from biomasses, safe and traceable food products, carbon storage in soil and plants and restoration of contaminated soils to agriculture.
This journal presents the first opportunity to bring together researchers from a wide number of disciplines within the agricultural chemical and biological sciences, from both industry and academia. The principle aim of Chemical and Biological Technologies in Agriculture is to allow the exchange of the most advanced chemical and biochemical knowledge to develop technologies which address one of the most pressing challenges of our times - sustaining a growing world population.
Chemical and Biological Technologies in Agriculture publishes original research articles, short letters and invited reviews. Articles from scientists in industry, academia as well as private research institutes, non-governmental and environmental organizations are encouraged.
