The effects of adding biochar rice husk (R), white popinee (WP), bamboo (BB), or coconut (CT) on microbial community in fermentation broths from glucose were investigated. The added biochars acted as biofilm carriers on which Sporolactobacillus spathodeae, Clostridium sensu stricto 11 sp., Clostridium sensu stricto 12 sp., Clostridium sensu stricto 1 sp., and Clostridium sensu stricto 5 sp. were enriched. Fermentation reactions substantially increased the amounts of acid-producers in biofilm. The homoacetogens, Clostridium carboxidivorans and Clostridium drakei, were identified in the biofilm in the first two batches of fermentation with biochars as electron conductors between acid-producers and homoacetogens to assist homoacetogenesis. The heterotrophic bacteria overcompeted the acid-producers in the biofilm in long-term fermentation.

用生物炭修饰的财团进行葡萄糖发酵：微生物财团转移。

研究了添加生物炭稻壳（R），白罂粟（WP），竹子（BB）或椰子（CT）对葡萄糖发酵液中微生物群落的影响。所添加的生物炭充当以下生物膜载体，即：Sporolactobacillus spathodeae，严格梭状芽孢杆菌11 sp。，严格梭状芽孢杆菌12 sp。，严格梭状芽孢杆菌1 sp。和严格梭状芽胞杆菌5 sp。被丰富了。发酵反应大大增加了生物膜中产酸剂的数量。在前两批发酵过程中，以生物炭作为产酸剂和高纯酶原之间的电子导体，以协助高纯乙酸生成，在生物膜中鉴定出了纯乙酸原，碳氧化梭菌和德氏梭状芽胞杆菌。在长期发酵中，异养细菌竞争生物膜中的产酸剂。
