According to reports, Shark Bay is one of the natural attractions that attract visitors to the coastline in Western Australia. It has always been controversial that when bacteria grow in a layer of stone and can barely touch visible sunlight, how do they survive? A recent Sydney Associate Professor Min Chen finally discovered this mystery.
Located in Western Australia, Shark Bay is known for its diverse natural beauty. It has the largest seagrass bed in the world, a large number of local animals, five endangered mammals, and 1/3 of Australian bird species. Shark Bay's greatest feature is the formation of laminated rocks and rock-like structures formed by blue-green algae.
Professor Chen of the University of Sydney discovered last year that cyanobacteria (one of the most common species of blue-green algae) in Shark Bay can utilize a chlorophyll that is distinct from other plants and bacteria for photosynthesis. This new chlorophyll is called "chlorophyll f" and it is the first new species discovered since 1943. She said, "completely unexpected." After the discovery of chlorophyll d in red algae, no one had found new varieties until 1996 when a team of Japanese researchers discovered that the main chlorophyll of cyanobacteria was growing in a strange place – there was only a small amount of sunlight at coral reefs. On the sea squirt.
Lamellar rocks are formed by cyanobacteria, calcium carbonate, and sediments. When cyanobacteria and other microorganisms grow in shallow water, some deposits deposit on them, forming rocky small rocks and gradually forming layers of layers. Lamellar stone. Prof. Chen grinds the sample and cultivates the microbes under near-infrared diodes. Finally, it was found that there is a different chlorophyll from cyanobacteria that absorbs more near-infrared light than typical pigments for photosynthesis.
The researchers said that this means that organisms containing this chlorophyll can expand the scope of photosynthesis, greatly increase the limits of solar energy use, and also help the application of daily life.
This revolutionary discovery helps tailor-make plastics and other polymers needed in everyday life such as paints, adhesives and lubricants. Chlorophyll, on the other hand, is a great invention in the natural world. Humans continue to explore and copy and use it. Key molecules allow plants and bacteria to photosynthesis, use solar energy and carbon dioxide in the air to make foods and fossil fuels, and provide the oxygen needed by the earth's creatures.
Professor Chen pointed out that "every step of photosynthesis is beneficial to humanity." Before coming to Australia to study for a doctorate in Sydney, Professor Chen studied Northeast Normal University in Changchun, Jilin, and began research on photosynthesis in 1998.
On October 12th, she was awarded the "Prime Minister's Prizes for Science 2011" by the Minister of Science and Technology of Australia. The award ceremony will be held in the Parliament building this time and a total of 5 awards will be awarded. The Prime Minister awarded the "Science Award" of 300,000 yuan to two chemists, Professor Lisa Sands of the Australian Academy of Sciences and Professor Solomon of the University of Melbourne.
