EM有效微生物技术在环境保护中的应用

综述了EM技术在工业废水治理、生活废水处理、畜禽养殖污染治理、河流湖泊环境净化、固体废物环境治理以及农村生态环境保护等环保领域中的应用,并对下一步EM技术的深入研究和应用提出了若干建议。

浅谈微生物与环境保护的关系

全球性环境恶化已给人类敲响了警钟，全球气候正在变暖，海平面上升、气候异常，自然灾害频繁；沙漠化正以每年5—7万平方公里的速度吞食着地表土壤，所以说环境保护不容怠慢，常规的方法已经很多了，本文主要介绍微生物在环境保护中起着重要的作用以及微生物在水污染治理、大气污染治理及微生物除臭、生物修复等方面的应用。

Security evaluation of compounded microbial flocculant

A new kind of compounded microbial flocculant (CMBF) for water and wastewater treatment has been developed through biological technology. In order to discuss its biological security, four groups of experiments, rat acute toxicity test via mouth, salmonella assay in vitro, mouse micronucleus in vivo test and teratogenesis test were conducted to evaluate its general toxicity, genotoxicity and generative toxicity. The experimental results showed that this type of compounded microbial flocculant was a substantial non-toxic substance based on the fact that LD50 value was over 10 mg/kg. The results from salmonella in vivo test and mouse micronucleus in vivo test revealed that the compounded microbial flocculant is a genetically non-toxic substance. Furthermore, compounded microbial flocculant has little effect on the growth of all the rats, and any morphologic abnormal phenomenon hasn’t appeared.

白色农业在六大领域的兴起

目前,国内外农业微生物资源的开发利用已在六大领域悄然兴起。 1.微生物食品。利用微生物发酵生产的“真菌肉”、食用油等在英国、法国、日本已规模化生产,由小球藻制成的食品面包也已在日本实现规模化生产,螺旋藻被联合国粮农组织称为“人类未来的粮食”,食用菌也是一种优秀的微生物食品,素有“植物肉”之称。国际食品界已将食用菌列为21世纪八大营养保健食品之一。中国的食用菌生产量和出口量居世界首位。
