摘要

世界各地都在使用鲜花，但由于它们的保质期较短，通常在使用一次后被丢弃。尽管产生了大量的废物，但对其的管理却很少。本研究探讨了花卉废弃物的厌氧消化，并评估了真菌预处理对该过程的影响，这方面的研究很少。经长直链木霉预处理的花渣在第9天出现甲烷峰，阳性对照在第18天出现甲烷峰。到第9天，真菌处理的花废物产生的甲烷比阳性对照多168.37%。宏基因组分析表明，真菌预处理样品具有较高的微生物多样性，梭状芽孢杆菌和拟杆菌的丰度高于阳性对照。据报道，梭状芽孢杆菌和拟杆菌的联合体可以提高系统的性能。因此，真菌预处理可以作为一种经济可行的方法来提高该过程的吞吐量。

Impact of fungal pretreatment on methane enhancement and microbiome dynamics in the anaerobic digestion of floral waste

Flowers are used all over the world, but because of their low shelf life, they are usually discarded after one-time use. Despite the huge amount of waste generation, its management is scarce. This study explores the anaerobic digestion of floral waste and assesses the impact of fungal pretreatment on the process, which is very less explored. Floral waste pretreated with the fungus Trichoderma longibrachiatum produced methane peak on day 9, while in positive control, methane peak was reported on day 18. Till day 9, fungal-treated floral waste produced 168.37 % more methane than the positive control. By metagenomic analysis, the fungal pretreated sample was revealed to have higher microbial diversity, and it was observed to have a higher abundance of Clostridium and Bacteroides than the positive control. Consortium of Clostridium and Bacteroides are reported to enhance system performance. Thus, fungal pretreatment can be used as an economically viable way to improve the throughput of the process.

期刊介绍： Biomass & Bioenergy is an international journal publishing original research papers and short communications, review articles and case studies on biological resources, chemical and biological processes, and biomass products for new renewable sources of energy and materials. The scope of the journal extends to the environmental, management and economic aspects of biomass and bioenergy. Key areas covered by the journal: • Biomass: sources, energy crop production processes, genetic improvements, composition. Please note that research on these biomass subjects must be linked directly to bioenergy generation. • Biological Residues: residues/rests from agricultural production, forestry and plantations (palm, sugar etc), processing industries, and municipal sources (MSW). Papers on the use of biomass residues through innovative processes/technological novelty and/or consideration of feedstock/system sustainability (or unsustainability) are welcomed. However waste treatment processes and pollution control or mitigation which are only tangentially related to bioenergy are not in the scope of the journal, as they are more suited to publications in the environmental arena. Papers that describe conventional waste streams (ie well described in existing literature) that do not empirically address ''new'' added value from the process are not suitable for submission to the journal. • Bioenergy Processes: fermentations, thermochemical conversions, liquid and gaseous fuels, and petrochemical substitutes • Bioenergy Utilization: direct combustion, gasification, electricity production, chemical processes, and by-product remediation • Biomass and the Environment: carbon cycle, the net energy efficiency of bioenergy systems, assessment of sustainability, and biodiversity issues.
