Fermented milks are consumed in many parts of the world and are relished for their acidic taste and health benefits. The aim of this study was to compare effects of different ratios of DL-type starter culture： mould Geotrichum candidum grown in milk on its viscosity and sensory properties on the 5th, 10th and 15th day of storage at 4 ~C~ in order to determine the best ratio to prepare fermented milk on basis of Iranian acceptance. We have examined the production of fermented milk by 80： 20, 70： 30, and 60：40 ratios of DL-type starter culture： mould Geotrichum candidum grown in milk. The results obtained from viscosity measurement and sensory evaluation showed no significant difference between these treatments used in the study and were not satisfactory; their viscosity was not accepted and scores attributed to odour and flavor of fermented milks by panelists were low.展开更多

The diagnosis was established by culture of dialysis fluid. The purpose of this report is to provide data on a fungal peritonitis due to a non-common agent.展开更多
从云南昆明地区的开菲尔粒中分离得到K2、Z7-1和Z8-4菌株,3株菌发酵产物可产生愉悦的花果香味。在基因组重测序基础上,分析菌株K2、Z7-1、Z8-4与白地霉(Geotrichum candidum)LMA-244基因组相似度,DNA杂交分析相似度分别为99.50%、99.40%...从云南昆明地区的开菲尔粒中分离得到K2、Z7-1和Z8-4菌株,3株菌发酵产物可产生愉悦的花果香味。在基因组重测序基础上,分析菌株K2、Z7-1、Z8-4与白地霉(Geotrichum candidum)LMA-244基因组相似度,DNA杂交分析相似度分别为99.50%、99.40%、99.50%;平均核酸一致性分析,相似度分别为98.66%、98.65%、98.68%。结合形态特征和26S rDNA序列同源性分析,K2、Z7-1和Z8-43株菌均鉴定为白地霉。利用基因本体论、京都基因与基因组百科全书(Kyoto Encyclopedia of Genes and Genomes,KEGG)、直系同源簇等数据库对白地霉K2进行基因功能注释,注释基因中40.74%与细胞组成相关,47.54%与生物过程相关,11.73%与分子功能相关。KEGG代谢途径分析发现萜类合成的相关基因,白地霉K2具有合成挥发性香味成分的遗传基础。采用气相色谱-质谱联用仪对白地霉K2菌株的发酵液挥发性成分进行检测分析,共检出50种挥发性成分,其中3-蒈烯、α-蒎烯和对伞花烃呈花香,L-α-松油醇呈松木香,4-萜烯醇、(-)-4-萜品醇呈丁香味,乙酸α-松油酯呈清甜香。推测白地霉是开菲尔酸奶香味物质的重要贡献菌株。本研究为白地霉K2用于发酵乳制品及其他发酵食品提供了理论基础。展开更多
