    , scientists have believed that microbes use serrogen to capture most of the ocean's solar energy. But in a study published August 7 in the journal Science-Progress, researchers found that bacteria with metamorphosis, a binding protein that uses retinal to capture light, play an important role in converting light into energy, especially in nutrient-poor areas.
    " chloroerin is important in the ocean, and now we find that another pigment is just as important. Co-author Laura Gómez-Consarnau, a biologist at the University of Southern California, said.
    all known phototrophic metabolism on Earth depends on three energy-converting pigments: chlorocerotein a, bacterial chlorocerotein a, and retinaldehyde (a pigment cluster in erythrome). The importance of chlorocerin in capturing solar energy has been studied for decades, but the contribution of phototrophics based on retinaldehyde to this process has not yet been studied.
    about 20 years ago, researchers discovered metamorphosis in marine bacteria, which uses light to pump protons out of cells, generating energy as protons flow back. In 2007, Gómez-Consarnau and colleagues demonstrated that bacteria can grow with this energy. In 2011, another group of scientists found that cyanobacteria uses light to maintain the size and energy levels of bacteria, adapting them to low nutritional conditions. Subsequent metagenomic studies confirmed the presence of the encoded protein erythrin gene in marine samples, but the scale of energy production using the protein worldwide is unclear.
    , a microbiologist at Technion, was the first author of a paper in 2000 describing the cyanosis. "We knew it was important, but we didn't realize it was such an important group of violet reds." "This paper actually put the numbers in there . . . It's something we haven't done before. The
    report the vertical distribution of three energy-converting pigments in the Mediterranean and Atlantic Oceans. They first developed a method for detecting resaldehyde and then collected seawater samples from different locations and depths in the Mediterranean and Atlantic Oceans. Because each visual erythrin binds to a molecule on the retinal aldehyde, they used this measurement to estimate the total number of cyanoglobins in each sample. The study found that the highest concentration of erythra was higher than the maximum value of cochlein a, and its geographical distribution was negatively corred with cochlelostr a. As alfalgen is most commonly found in malnourished waters in the Mediterranean, waters with lower levels of erythrogen tend to have higher levels of erythrin.
    the team recorded the position and light intensity of each sample in the water column, and then estimated how much light was captured using the violet level. The evaluation showed that the deformed erythrogen could provide enough energy to keep the bacteria alive. The researchers then performed a similar calculation based on the abundance of yelorotin a (microalgae are used for photogenics). They found that the alfalfa absorbs at least as much light as curch a, and that the light is sufficient to maintain the bacteria's underlying metabolism.
    , deformation of the erythrogen may capture more light energy. For example, in the eastern Mediterranean, the author's upper limit for solar energy capture based on deformed doppaphenol is estimated at 107 kJ per square metre per day, while in the same region, the upper limit for yelorophosta capture is estimated at 19 kJ per square metre per day. This shows that deformed erythrogen is the main energy transfer mechanism for acquiring solar energy on the ocean surface.
    " is a great paper because it gives us the number of activists in the system. Stephen Giovannoni, a microbiologist at Oregon State University, said, "It explains that where there is no photomatery to produce carbon, cells are more limited in their energy acquisition, and the system is starting to play a bigger role." He added, "But there are still questions about how cells use this power and what role it plays in its life cycle." '
    role of alfalegyptics in the global carbon cycle is also unclear,' said Dr. Gómez-Consarnau. As a result of climate change, the oceans are warming and the nutrients in the sea are drying up. This means that this process may become more important in the future. At the same time, if there is no nutrition, photo-cooperation will be reduced, so we may see the rebalancing of the oceans. The
