Patents on cyanobacteria and cyanobacterial products and uses

Abstract

This chapter focuses on patenting activity with respect to cyanobacteria since about 2008. The chapter mainly concerns US patents and Patent Cooperation Treaty (PCT) patent applications, although some other country‐specific patents and applications are included. Two recent patent applications describe methods for controlling cyanobacterial blooms. There has been increased application of genetic engineering to produce improved cyanobacterial strains for various industrial applications. Several patents concern the production, extraction, and purification of carotenoids or phycobilin pigments from cyanobacteria as well as the use of these phycobilin pigments such as allophycocyanin in creating fluorescent conjugates for use as fluorescent markers. By far the largest number of recent patents relate to improving cyanobacteria by genetic engineering for the production of biofuels. Specific cyanobacterial genes for various applications have also been the subject of patenting activity.
