Investigation of diazotrophic endopytes in sugar-rich crops

人类引起的气候变化可能是人类面临的最大环境挑战。 减少温室气体排放的解决方案之一是更多地依赖生物、环境和经济有效的生物燃料。 虽然北美非常重视从玉米和小麦中提取生物乙醇，但如果不解决生产这些作物所需投入产生的温室气体排放问题，温室气体的节省将是微不足道的。氮肥的生产和使用是这些作物生产中温室气体产生的最大单一来源。 这主要是因为在田间施用氮肥后，一部分氮肥转化为一氧化二氮，一种比二氧化碳强300倍的温室气体。

Human-induced climate change maybe the greatest environmental challenge ever faced by humankind. Amongst the solutions to decrease greenhouse gas emissions is a greater reliance on biologically, environmentally, and economically effective biofuels. Although much emphasis in North America has been put on bioethanol derived from corn and wheat, without addressing the greenhouse gas emissions derived from the inputs required to produce these crops, the greenhouse gas savings will be marginal. The production and use of nitrogen (N) fertilizer is the single largest source of greenhouse gas production in the production of these crops. This is largely due to the fact that after its application in the field a proportion of N fertilizer is converted to nitrous oxide, a gas which is 300 times more powerful than carbon dioxide as a greenhouse gas.
