The pectic substances can be classed protopectins, pectins and pectin acids。 果胶物质分成原生质果胶,果胶和果胶酸。
Calcium pectate has been invoked as a material that binds together the cell walls of plants . 果胶酸钙起着粘结细胞壁物质的作用。
The best studied inducible and repressible enzyme in phytopathogenic prokaryotes is endo - pectate lyase in e . carotovora 植物病原原核生物中研究得最清楚的是胡萝卜软腐菌的果胶酸内裂解酶。
During the incubation of e . carotovora with combined glucose and pectate , two exponential growth phases occur as the bacteria first consume glucose , the preferred substrate , then pectate , the more slowly utilized substrate 在用葡萄糖与果胶酸同胡萝卜软腐菌共培养时,出现两个指数生长期,一个发生在细菌先利用葡萄糖这种容易利用的底物时,第二个出现在利用果胶酸这种利用得更慢的底物时。
