摘要

利用潜在微生物进行可生物降解固体废物管理是一门新兴的科学。微生物在有机固体废物的循环利用中起着重要的作用。因此,本项目旨在从当地相关分解基质中分离出潜在的本地非植物病原真菌,用于有机废物循环利用作为生物有机肥(BOF)。共分离到13株真菌。应用13种分离真菌悬浮液对绿豆(Vigna radiata)、芥菜(Brassica campestris)和小麦(Triticum aestivum)种子的萌发进行了评价。与对照相比,RW-T02、PL-P01和CD-T01/MSW-T05处理的绿豆、芥菜和小麦的发芽率分别显著提高(98.35%)、96.65%和93.35%。但在大多数情况下,真菌处理并没有促进胚根和胚珠的长度。对照处理中绿豆和芥菜的胚根和胚芽最长。相反,在小麦中,MSW-T05和RW-T03处理的胚根和胚粒长度分别最长。基于发芽率和胚根/胚芽长度的优异表现,选择了6株真菌进行混合培养的相容性试验。在相容性试验中,两个真菌组合(ABF和BCE)表现出较好的相互混种现象。这些组合可能在有机废物的生物降解中发挥重要作用。

Exploration of Potential Indigenous Non-phytopathogenic Fungi for Bio-organic Fertilizer Recycling from Organic Waste
Using potential microbes in biodegradable solid waste management is an emerging science. Microbes play a significant role in recycling of organic solid wastes. Therefore, the present project was carried out to isolate indigenous potential non-phytopathogenic fungi from local relevant decomposed substrates for the purpose of organic waste recycling as bio-organic fertilizer (BOF). A total of thirteen fungal strains were isolated. Seven of them were identified as Trichoderma spp., and the rest were Penicillium spp. Germination of mung bean (Vigna radiata), mustard (Brassica campestris), and wheat (Triticum aestivum) seeds were assessed by application of 13 fungal isolate suspensions. Significant increase of germination percent was achieved in mung bean (98.35%), mustard (96.65%), and wheat (93.35%) by fungal treatments RW-T02, PL-P01, and CD-T01/MSW-T05, respectively, compared to the controls. But radicle and plumule lengths were not promoted by fungal treatments in the majority of cases. Significantly, the longest radicle and plumule lengths of mung bean and mustard were found in control treatments. Conversely, in wheat the longest radicle and plumule length were achieved in treatments MSW-T05 and RW-T03, respectively. Based on superior performances of percent germination and radicle/plumule length, six fungal isolates were selected for compatibility performance in mixed cultures. In the compatibility tests, two fungal combinations (ABF and BCE) presented superior mutual intermingle appearances. Perhaps these combinations may play significant roles in biodegradation of organic wastes.

期刊介绍: The Environment and Natural Resources Journal is a peer-reviewed journal, which provides insight scientific knowledge into the diverse dimensions of integrated environmental and natural resource management. The journal aims to provide a platform for exchange and distribution of the knowledge and cutting-edge research in the fields of environmental science and natural resource management to academicians, scientists and researchers. The journal accepts a varied array of manuscripts on all aspects of environmental science and natural resource management. The journal scope covers the integration of multidisciplinary sciences for prevention, control, treatment, environmental clean-up and restoration. The study of the existing or emerging problems of environment and natural resources in the region of Southeast Asia and the creation of novel knowledge and/or recommendations of mitigation measures for sustainable development policies are emphasized. The subject areas are diverse, but specific topics of interest include: -Biodiversity -Climate change -Detection and monitoring of polluted sources e.g., industry, mining -Disaster e.g., forest fire, flooding, earthquake, tsunami, or tidal wave -Ecological/Environmental modelling -Emerging contaminants/hazardous wastes investigation and remediation -Environmental dynamics e.g., coastal erosion, sea level rise -Environmental assessment tools, policy and management e.g., GIS, remote sensing, Environmental -Management System (EMS) -Environmental pollution and other novel solutions to pollution -Remediation technology of contaminated environments -Transboundary pollution -Waste and wastewater treatments and disposal technology
