Biogas is one of the practical vitality sources of energy that can be delivered from numerous sorts of biomass. Biogas production from fresh digestate bacterial crude culture; Providencia alcalifaciens and Alcaligenes aquatilis isolated from municipal wastewater treatment plants located in Port Said, Egypt and identified with 16S rRNA; amended with aquatic macrophytes; Pistia stratiotes and Potamogeton pectinatus, collected from some irrigation canals in Port Said, Egypt as a substrate in the presence of different concentrations of chemically prepared nickel oxide nanoparticles (NiONPs) subjected to anaerobic conditions were successfully investigated. The produced biogas was collected by the water displacement method and subsequently measured using GC/MS analysis. As found in this present work, the optimum NiONPs concentration was 2 ppm for biogas production, where the highest productivity was 42.90 mL and 31.33 mL/3.4 g of P. stratiotes and P. pectinatus with enhancing % 87.91% and 82.38%, respectively compared with the control (without NiONPs) at 30 days of incubation period. Biogas production was slightly greater using P. stratiotes than P. pectinatus particularly with the addition of NiONPs. The present examination may have a noteworthy task in the generation of reasonable biogas amounts utilizing monetary wellsprings of reusing the horrible water system trenches macrophytes and control of environmental defilement issues that may have come about in light of these unfortunate macrophytes.

氧化镍纳米颗粒在提高利用某些废水细菌和水生植物生物质的沼气生产中的应用

沼气是可以从多种生物质中释放出来的实用生命力能源之一。从新鲜的消化细菌粗培养物中生产沼气；的Providencia alcalifaciens和产碱杆菌属aquatilis从位于塞得港，埃及并用的16S rRNA确定市政污水处理厂中分离; 用水生植物进行修订；开心果和Potamogeton pectinatus从埃及塞得港的一些灌溉渠中收集的水作为底物，在存在不同浓度的化学制备的氧化镍纳米颗粒（NiONPs）的条件下，已成功进行了研究。通过水置换法收集产生的沼气，然后使用GC / MS分析进行测量。正如目前的工作所发现的，用于沼气生产的最佳NiONPs浓度为2 ppm，其中最高生产率为42.90 mL和31.33 mL / 3.4 g P. stratates和pectinatus，分别提高了87.91％和82.38％的百分比。在温育期30天与对照组（无NiONP）一起使用。沼气产量稍大使用P. stratiotes比P.嗜特别是添加NiONP。当前的检查在利用货币水源来产生合理的沼气量方面可能具有值得注意的任务，这些货币源重用了可怕的水生植物，并控制了因这些不幸的大型植物而引起的环境污染问题。
