摘要:

柑橘罐头加工产生大量果胶污泥,利用高效菌株的快速腐解将果胶污泥转化成栽培基质,实现高持水难处理果胶污泥的资源化利用。结果表明,筛选的康宁木霉(Trichoderma koningii)LZ51果胶酶活性达684 U·mL-1;将果胶污泥分别和秸秆、蛭石混合发酵制得秸秆果胶基质(M1)、蛭石果胶基质(M2),在红樱桃萝卜、大叶菠菜和四季香葱发芽和育苗过程中发现,M1和M2的使用性能较蛭石基质(CK)均有显著提升。其中,M1对3种蔬菜的发芽率较CK平均提升5%;在育苗阶段,M1培育的樱桃红萝卜鲜重较CK增加30%,培育的大叶菠菜鲜重较CK增加50%。利用果胶污泥和秸秆混合发酵制备一种新型栽培基质,为罐头加工的果胶污泥资源化利用开辟一条新的利用途径,市场前景广阔。

Abstract:

The processing of citrus canning produces a large amount of pectin sludge, which was converted into a cultivation substrate using the rapid putrefaction of efficient strains to achieve the resourceful utilisation of pectin sludge that is difficult to be treated with high water-holding capacity. The results showed that the pectinase activity of Trichoderma koningii LZ51 reached 684 U·mL-1; straw pectin substrate (M1) and vermiculite pectin substrate (M2) were produced by mixing and fermenting pectin sludge with straw and vermiculite, respectively, and it was found that the germination and seedling development of cherry red radish, large-leafed spinach and four-season chive were better than that under vermiculite substrate (CK) culture. both had significantly higher performance than vermiculite substrate (CK). In particular, M1 increased the germination rate of the three vegetables by an average of 5% compared with CK; at the seedling stage, M1 produced a 30% increase in fresh weight of cherry red radish compared with CK, and a 50% increase in the fresh weight of large-leaf spinach compared with CK. The use of pectin sludge and straw mixed fermentation to prepare a new type of cultivation substrate opens up a new utilisation pathway for the resourceful utilisation of pectin sludge from canning processing, which has a promising market prospect.
