微生物资源的开发和利用

生物资源开发利用 自从有了人类,天天与动植物打交道,利用动植物作 为人类食物的主要来源; 现代工业、农业更是大规模开发利用动植物为人类服 务; ■由于过度或不合理开发,环境恶化,沙漠化加剧,动 植物资源急剧减少,造成了长期的、甚至是难以弥补 的损失; ■地球上动植物资源急剧减少已成为一个国际化问题; 我们只有一个地球,“生物多样性公约”就是全世界近 200个签字国保护生物多样性最高意志的体现,由此 许多国家都把可持续性发展战略作为基本国策

And experimentation retreat ed from biotech start-ups to govern- ment and academic laboratories, where it has remained in relative obscurity Now,some 30 years later, bioremedi- r ation is slowly and gingerly staging a comeback. Naturally occurring mi crobes have been tried at a few sites with some limited success. Since 1998. for example, one group has been successful ly cleaning up a carbon tetrachloride spill in Michigan using natural bacte mported from California. Elsewhere, strains of Pseudomonas bacteria have succeeded in remediating halogenated hydrocarbons like trichloroethylene And in October. the Department of En ergy (DOE) will perform its first-ever field test of bioremediation to clean up I( one of its heavily polluted sites.
