Chlorophyll F found in ancient bacteria to help algae grow more efficiently

Until now, researchers only knew four types of chlorophyll used by plants in photosynthesis process. But, recently they said they found at Shark Bay on the Western Australian coast a new type of chlorophyll in ancient bacteria, that could provide new ways to grow algae (used to create biofuel) more efficiently.
The new type of chlorophyll found in stromatolites (layered structures of cyanobacteria living in shallow waters) could make a better use of available light. “That makes this new discovery the reddest chlorophyll to be identified so far…It was found deeper in the stromatolite structure, which explains why it needs the longer wavelengths of light for photosynthesis.”, said professor Robert Willows of Sydney’s Macquarie University.
Scientists have Developed an Artificial Leaf that Produces Hydrogen

It seems that nature continues to be a model for researchers who daily try to imitate natural systems for the development of new technologies. One of the most controversial natural processes is photosynthesis because the ability to harness and utilize sun’s energy can help develop amazing technologies. An example is the artificial leaf from the image and as the researchers say, it is able to separate water in oxygen and hydrogen, and generate hydrogen.
New Enzyme Allows Plants to Grow in Dry and High CO2 Conditions

Increasing levels of CO2 in the atmosphere and reduction of water resources are two major problems on our planet. Despite these degradation processes, researchers at the University of California San Diego have discovered some plant enzymes able to solve these two problems simultaneously.
In other words, these special enzymes can allow plants to save water while consuming more carbon dioxide. In this way water resources will be saved and the amount of CO2 in the atmosphere will be reduced.

Finally some green tendencies from oil companies. Despite opposing for years the idea of renewable energy, the oil giant Exxon Mobile Corporation, with a 2008 revenue of $442.9 billion and the distinction of “the most profitable company in the world” acquireing $45.2 billion last year, announced a $600M “injection” into algae-based biofuel research.
