PROGRESS REPORT CULTIVATION ON SEWAGE OF MICROALGAE HARVESTABLE BY MICROSTRAINERS

摘要

The present crisis in natural gas supplies is expected to worsen within a decade;new technologies capable of providing alternative methane sources must be rapidly developed. A multiplicity of approaches to synthetic natural gas production through bioconversion exists. This project deals with the development of biomass production technology for planktonic microalgae.nA review of this subject details the use of such algae in waste treatment and the problem of harvesting the many types of microscopic algae occurring in ponds. The solution of this problem is deemed to be development of algal species control techniques which allow cultivation of desirable algal types harvestable through the most economic methods available. Two methods of algal species control are presented in detail—the theory of size selective biomass recycle and the selection and cultivation of nitrogen-fixing blue-green algae.
