Molecular identification and relative abundance of microorganisms in douchi koji and salted egg white sufu during processing

A novel animal protein-based douchi koji-inoculated steamed salted egg white sufu (SEWS) has been developed. This study determined the relative abundance of microorganisms in the douchi koji and semi-finished (5-day fermentation) and finished (5-day fermentation and 14-day ripening) SEWS by using 16S and 18S ribosomal DNA and gene-cloning methods. The results revealed that Bacillus spp. and Aspergillus oryzae were dominant in the douchi koji. In the semi-finished SEWS, the percentages of Bacillus amyloliquefaciens and Bacillus subtilis were considerably lower, whereas those of Enterococcus and Staphylococcus were substantially higher. In the finished SEWS, Bacillus spp. became dominant again and A. oryzae was the only fungus detected. In conclusion, by using molecular techniques, microbial population dynamics in SEWS can be evaluated. During processing, the relative abundance of microorganisms in SEWS changed and Bacillus spp. and A. oryzae remained dominant. This study provides crucial information for designing starter cultures for producing SEWS.     

Study on Design of Bio-clean Operating Room

The design of Bio-clean operating room in modern hospital is quite different from that of traditional operating room. This paper discusses three aspects of Bio-clean operating room design: air clean standard and air purification, interior equipment system and interior finish. It is hoped that this discussion will conduce to later designs.

敦煌西晋画像砖所绘“白象”形象溯源

敦煌佛爷庙湾西晋早期墓出土的白象画像砖,是佛教在当时被视为一种神秘性方术而存在的现实表现。本文对敦煌西晋画像所绘“白象”形象进行溯源,认为画像砖上的六牙白象应该是中国早期佛教朝着神秘主义方向发展的一个缩影。     

农村妇女能力开发在发展贵州草地畜牧业标准化中的作用

着眼于农业从传统方式向现代农业演变的历史性进程,采用实证分析方法,具体分析了贵州省农村妇女的普遍性别特点及其在草地畜牧业标准化中的重要作用,指出进一步加强对贵州农村妇女能力这一人力资源的开发,不但对发展草地畜牧业标准化本身,而且对于发挥农村妇女的巨大潜力,促进贫困山区的开发式脱贫,推动贵州省现代农业发展进程,都具有十分重要的意义。最后就如何加强农村妇女能力开发,以及要注重创新对这一特殊群体的培训方式等方面提出了建议。     

大力推行国际标准化草地畜牧业建设促进贵州喀斯特山区生态畜牧业可持续发展
