Degradation and biosynthesis of terpenoids by lactic acid bacteria isolated from cheese: first evidence
The aim of this study was to investigate whether lactic acid bacteria (LAB), isolated from cheese, were able to degrade terpenes. Five strains of LAB were grown on M17 and reconstituted skim milk in the presence of alpha-pinene, beta-myrcene, alphaterpineol, myrtenal, and alpha-campholenal. Cultures were incubated at 37 °C and samples collected at 6, 24, and 48 h for analysis by headspace-solid...

متن کاملEffects of trace elements and calcium on diabetes and obesity, and their complications: Protective effect of dairy products A mini-review
Trace elements and minerals influence the pathogenesis of obesity and diabetes and their complications, mainly through their involvement in peroxidation and inflammation. On the other hand, peroxidation and inflammation are liable to alter themetabolism of these nutrients, which should be taken into account when assessing their status. Milk products are capable of preventing iron-induced peroxi...
متن کاملInvestigation of Ion Channel Mechanism of Regulatory - Volume - Decrease
【摘要】 研究背景 细胞在新陈代谢和完成各种生理功能过程中,不断面临着细胞内外渗透活性分子在细胞内外的流动,从而不断产生细胞内外渗 透压的变化,使细胞处于不断变化的渗透梯度中。由于细胞对水的自由通透性,水分会依据渗透梯度通过渗透或水通道流入或流出细胞,从而产生 细胞容积的变化。可见既使在正常生理条件下,细胞的容积也处于不断的变化中,与此相适应,许多细胞进化了自身的细胞容积调节功能,即当细 胞受到非等渗刺激而产生容积增大或缩小时,细胞自身会通过调节机制使变化了的细胞容积向正常体积恢复。细胞的容积调节功能在细胞的免疫应 答、细胞的迁移、细胞的增殖与分化过程中具有十分重要的意义。 细胞的容积调节功能主要包括两种:一种为调节性细胞容积增大(regulatory vol ume increase,RVI),指当细胞受到高渗透压的刺激而皱缩后,细胞能够调节性的使已经皱缩的细胞体积向正常体积恢复;...
متن کاملDairy propionibacteria as human probiotics: A review of recent evidence
Probiotics have been the subject of intensive research, mainly focusing on bifidobacteria and lactic acid bacteria. However, there is evidence that dairy propionibacteria also display probiotic properties, which as yet have been underestimated. The aim of this paper is to review recent data which report probiotic characteristics of dairy propionibacteria and to distinctly organise them based on...
