Australian researchers found new chlorophyll

Researchers from the school of life sciences at the University of Sydney announced Tuesday that they have discovered a new type of chlorophyll, which is expected to have broad application prospects in the field of bioenergy The chlorophyll was accidentally extracted from a colony of cyanobacteria in Shark Bay, Western Australia, and was named chlorophyll F The results show that chlorophyll f can participate in photosynthesis by light with an upper limit of 720 nm, which is in the near infrared region, 10 nm longer than the upper limit of chlorophyll d and 40 nm longer than the upper limit of chlorophyll a Photosynthesis is the process of transforming light energy into chemical energy by synthesizing some organic compounds Chlorophyll is the most important pigment related to photosynthesis The scientific community once thought that chlorophyll could only absorb visible light between 400nm and 700nm to participate in photosynthesis, but scientists found in 1996 that chlorophyll d could absorb near-infrared light with 710nm spectrum to participate in photosynthesis Australian researchers believe that the discovery of chlorophyll f will rewrite some basic ideas about chlorophyll's participation in photosynthesis The research was published in a new issue of the American journal Science on the 20th The researchers said that chlorophyll f can absorb light closer to the infrared region, which shows that photosynthetic organisms can use a much larger spectrum than previously thought by the scientific community, and the efficiency of photosynthesis is far beyond the imagination of the scientific community The researchers believe that chlorophyll f is expected to be widely used in the field of plant biotechnology and bioenergy.
