Changes in microorganisms and metabolites during long-term fermentation of commercially manufactured anchovy sauce

引用

Food Science and Human Wellness 2024年

作者： Daehyeon Kim Seong-Eun Park Eun-ju Kim Seung-Ho Seo Kwang-Moon Cho Sun Jae Kwon Hong-Seok son Department of Biotechnology， College of Life Sciences and Biotechnology， Korea University sonlab Inc. 3. AccuGene Inc.

This study was performed to investigate the changes in microbial communities and metabolites during the long-term fermentation of commercially manufactured anchovy sauce. Samples of commercial anchovy sauce were collected from large-scale fermentation tanks with fermentation periods of up to 7.87 years. The complex bacterial community was simplified to two genera， Tetragenococcus and Halanaerobium， after approximately 0.55 years of fermentation. Although genera， such as Saccharomyces， Cladosporium， Candida， and Aspergillus， were relatively dominant， no clear pattern was identified in fungal community analysis. The longitudinal metabolite profile demonstrated that approximately half (55.8%) of the metabolites present in anchovy sauce were produced within a year of fermentation due to rapid fermentation. Despite the static microbial community， the contents of several metabolites including amino acids and biogenic amines changed continuously during the long-term fermentation of anchovy sauce. This study provides novel insights into the changes in microbiota and metabolites in fish sauce produced without any starter inoculation.

本文将介绍一种采用了微分(derivative)叠加线性化技术的28GHz CMOS毫米波下变频混频器,以及我们为5G蜂窝通信系统所设计的低耦合源负反馈电感器,以此来改善下变频混频器的线性性能。在的情况下,本文所提出的低磁耦合源极负反馈电感器可避免原理图设计(不考虑磁耦合)与布局设计中(考虑了源极负反馈电感器引起的磁耦合效应)之间的线性退化差距。带有本地振荡器缓冲器的下变频混频器是通过采用65nm CMOS技术实现,并且IV电源电压时的电流为21m A。在26.5-29.5GHz的频率范围内,它的增益为10.1dB,噪声系数低于10dB,三阶输出截取点为19.3dBm。
