工业废弃物可以被收集和改性以分析微生物生长。木质纤维素提取技术提供了分析特定生物降解能力的组分。气相色谱-质谱法可识别在制浆废料上生长的微生物的发酵产物。这些方法确定微生物降解碎浆废料的代谢能力。

以下实验的总体目标是确定微生物或微生物群落利用制浆废料黑液促进生长、用于生长的黑液成分以及这种制浆废料的微生物代谢产生的产物的能力。这是通过收集制浆废液黑液并准备用作培养基成分来实现的。作为第二步,提取木质纤维素成分,用于确定微生物的碳源需求。

接下来,制备、接种并分析培养基的微生物生长情况,以确定微生物在黑液及其成分上生长的能力。结果表明,微生物环境分离物利用黑液作为代谢产物生长和合成的唯一碳源,基于其在最小培养基琼脂平板上可视化的生长,以及 GCMS。当我们讨论微生物能够在纸浆废料上生长的可能性,并且我们可能能够直接从纸浆厂分离这些微生物时,我们第一次想到了这种方法。
