A green biorefinery enables the material and energetic use of biomass via lactic acid and methane production. Different ensiling techniques were applied to maize and amaranth with the aim to increase the amount of lactic acid in the silage. In addition the methane formation potential of the ensiled samples and the remaining solid residues after separating the organic juice were assessed. Treating maize with homofermentative lactic acid bacteria in combination with carbonated lime increased the amount of lactic acid about 91.9%. For amaranth no additional lactic acid production was obtained by treating the raw material. Specific methane yields for the solid residues of amaranth were significantly lower in comparison to the corresponding silages. The most promising treatment resulted in a production of 127.9±4.1 g kg(-1) DM lactic acid and a specific methane yield for the solid residue of 349.5±6.6 lN kg(-1) ODM.
绿色生物炼制厂通过乳酸和甲烷的生产实现生物质的物质和能量利用。采用不同的青贮技术对玉米和苋菜进行处理，目的是增加青贮料中的乳酸含量。此外，还评估了青贮样品的甲烷生成潜力以及分离有机汁液后剩余的固体残渣。在与碳酸石灰结合使用同型发酵乳酸细菌处理玉米时，乳酸的含量增加了约 91.9%。对于苋菜，未经处理的原料没有额外产生乳酸。与相应的青贮料相比，苋菜固体残渣的特定甲烷产率明显较低。最有前途的处理方法可生产 127.9±4.1 g kg(-1) DM 乳酸和 349.5±6.6 lN kg(-1) ODM 固体残渣的特定甲烷产率。
