Abstract

Azolla is often considered an invasive weed because of the rapid colonization of water surfaces. It is a free-floating aquatic fern, known for its N fixing potential, short doubling time, and bioremediation potential. It has several applications as green manure, N biofertilizer, cattle, chicken, and fish feed supplements because of its high protein content. It can grow on wastewater improving its quality. Azolla biomass thus produced can be utilized for energy production. It has been used for the production of biogas. Recently, its bio-oil potential has been studied. Azolla biomass has been used for biodiesel, biogas, and bio-hydrogen production. The exploitation of Azolla biomass as feedstock for bioenergy needs critical evaluation.

水生杂草Azolla作为生物能源和饲料补充剂的可持续原料的新应用的关键评价
亚速拉通常被认为是一种入侵性杂草,因为它能在水面快速定植。它是一种自由漂浮的水生蕨类植物,以其固氮潜力、短倍增时间和生物修复潜力而闻名。由于其蛋白质含量高,它在绿肥、氮生物肥料、牛、鸡和鱼饲料补充剂中有多种应用。它可以在废水中生长,提高水质。由此产生的紫苏生物量可用于能源生产。它已被用于生产沼气。近年来,人们对其生物油潜力进行了研究。紫苏生物质已被用于生物柴油、沼气和生物制氢。利用紫苏生物质作为生物能源原料需要进行严格的评估。

期刊介绍: Published since 1993, Environmental Reviews is a quarterly journal that presents authoritative literature reviews on a wide range of environmental science and associated environmental studies topics, with emphasis on the effects on and response of both natural and manmade ecosystems to anthropogenic stress. The authorship and scope are international, with critical literature reviews submitted and invited on such topics as sustainability, water supply management, climate change, harvesting impacts, acid rain, pesticide use, lake acidification, air and marine pollution, oil and gas development, biological control, food chain biomagnification, rehabilitation of polluted aquatic systems, erosion, forestry, bio-indicators of environmental stress, conservation of biodiversity, and many other environmental issues.
