We tried to develop an algal system for simultaneous removal of CO_2 and NOx in flue gas. It is important to recycle carbon dioxide and we investigated the development of an effective technique to recycle algal biomass produced in this CO_2/NOx treatment system. This technique was applied to use cyanobacterial biomass collected from eutrophic lakes. It was shown that algal and cyanobacterial biomass could be used to produce hydrogen gas or biosorbent for heavy metals.1. Analysis of algal biomass.The component of algal biomass was analyzed to optimize the utilization method.2. Hydrogen production from algal biomass.Hydrogen was produced by photosynthetic bacterium, Rhodobium marinum A-501, from lactic acid, which was produced by Lactobacillus amylovorus from starch contained in algal biomass. Furthermore, it was possible to produce hydrogen directly from algal biomass using mixed culture or R. marinum A-501 and L. amylovorus.3. Heavy metal removal from environmental water by microalgae.In environmental water, Ca and Mg ions are contained at high level. Heavy metals, such as Zn, Cd, Cu, and Pd were found to be removed in the presence of Ca or Mg ion.

我们试图开发一种同时去除烟气中CO_2和NOx的藻类系统。在CO_2/NOx处理系统中，我们研究了一种有效回收藻类生物量的技术。该技术应用于从富营养化湖泊收集的蓝藻生物量。结果表明，藻类和蓝藻生物量可用于生产氢气或重金属的生物吸附剂。藻类生物量分析。通过分析藻类生物量组成，优化利用方法。藻类生物质制氢。光合细菌Rhodobium marinum A-501从乳酸中产生氢气，乳酸由淀粉样乳杆菌从藻类生物质中的淀粉中产生。此外，还可以通过混合培养的方式直接从藻类生物质中生产氢气，或将海洋r.m arinum A-501和L. amylovorus混合培养。微藻去除环境水中重金属。环境水体中钙、镁离子含量较高。在Ca或Mg离子存在的情况下，重金属如Zn、Cd、Cu和Pd被去除。
