Fresh potatoes are one of the commodities with the highest wastage rates. A green, sustainable, and productive technology for the enzymatic generations of ammonium gluconate from potatoes was developed. The process comprised simultaneous α-amylase and glucoamylase treatment and fermentation to produce glucose. The final glucose yields after 40 h were around 90 g/L. The glucose was then converted to ammonium gluconate by fermentation for 36 h. Analysis of the ammonium gluconate showed a carbon content of 33.73%, a nitrogen content of 6.585%, and a sulfur content of 0.091%. The ammonium gluconate softened seed coats, increasing both water uptake and germination. It also enhanced the activity of α-amylase which loosened the seed endosperm cells and hydrolyzed their amyloplast. Ammonium gluconate also increased the number of dividing cells, thereby increasing the length of the apical meristematic zone, which, in turn, promoted the elongation and growth of roots. In conclusion, ammonium gluconate produced by waste potatoes can be used as a good seed-soaking agent or seed coating, which has the potential for widespread agricultural application.

新鲜马铃薯是浪费率最高的商品之一。开发了一种用于从马铃薯中酶促产生葡萄糖酸铵的绿色、可持续和高产技术。该过程包括同时进行α-淀粉酶和葡糖淀粉酶处理和发酵以产生葡萄糖。40 小时后的最终葡萄糖产量约为 90 g/L。然后通过发酵36小时将葡萄糖转化为葡萄糖酸铵。葡萄糖酸铵的分析表明碳含量为33.73%，氮含量为6.585%，硫含量为0.091%。葡萄糖酸铵软化种皮，增加水分吸收和发芽。它还增强了α-淀粉酶的活性，使种子胚乳细胞松散并水解其淀粉体。葡萄糖酸铵也增加了分裂细胞的数量，从而增加顶端分生组织区的长度，进而促进根的伸长和生长。综上所述，废马铃薯生产的葡萄糖酸铵可作为良好的浸种剂或种衣剂，具有广泛的农业应用潜力。
