Scientists discovered a new type of bacteria living in coral that can produce vitamin B12 at levels up to 284 micrograms per milliliter. According to Gram Research analysis, this newly identified bacterium, named Jujubicoccus corallicola, represents a completely novel species found in Porites coral. While this discovery is exciting for potential future applications in sustainable vitamin B12 production, it remains in early laboratory stages and won’t immediately change how we obtain this essential nutrient.
Scientists discovered a brand-new type of bacteria living inside coral that has an amazing ability: it can make vitamin B12, the nutrient our bodies need for healthy nerves and blood cells. Researchers found this bacterium, called Jujubicoccus corallicola, in coral samples and identified it as a completely new species. The bacteria can produce large amounts of vitamin B12 in laboratory conditions. This discovery is exciting because it shows how ocean creatures and the tiny organisms living with them work together, and it might help scientists find new ways to produce this important vitamin in the future.
Key Statistics
A 2026 research article published in the International Journal of Systematic and Evolutionary Microbiology identified a novel bacterial strain isolated from Porites coral that can produce up to 284 micrograms of vitamin B12 per milliliter of culture medium.
The newly discovered bacterium, Jujubicoccus corallicola, shares only 92.2% genetic identity with the closest known bacterial species, confirming it represents a completely new species within the order Rhodobacterales.
The bacterial strain can survive in temperature ranges of 20-37 degrees Celsius and salt concentrations of 0-6%, making it well-adapted to marine coral reef environments.
The Quick Take
- What they studied: Scientists wanted to identify and understand a new type of bacteria they found living in coral and learn about its special ability to produce vitamin B12.
- Who participated: The study examined one bacterial strain (GXU_MW_L88T) isolated from Porites coral samples collected from marine environments.
- Key finding: The newly discovered bacteria can produce up to 284 micrograms of vitamin B12 per milliliter of growth medium, making it a potentially valuable source for producing this essential nutrient.
- What it means for you: While this is basic science research, it could eventually lead to new, sustainable ways to produce vitamin B12 supplements. However, this discovery is still in early laboratory stages and won’t immediately change how we get our vitamins.
The Research Details
Scientists collected samples from coral and used laboratory techniques to isolate and identify a new bacterial strain. They examined the bacteria’s physical characteristics, including its shape, size, and how it responds to different temperatures, salt levels, and pH conditions. The researchers then compared the bacteria’s genetic code (DNA) to known bacteria species to confirm it was completely new. They also tested the bacteria’s ability to produce vitamin B12 and measured how much it could make under ideal laboratory conditions.
This research approach is important because it combines multiple methods to properly identify and classify new organisms. By comparing genetic sequences and physical characteristics, scientists can be confident they’ve found something truly new. Testing the bacteria’s vitamin B12 production shows it has practical potential beyond just being an interesting discovery.
This study was published in a peer-reviewed scientific journal, meaning other experts reviewed the work before publication. The researchers used standard laboratory techniques and genetic analysis methods that are widely accepted in microbiology. However, this is a single-strain study, so findings are limited to this one bacterium. The bacteria was only tested in laboratory conditions, not in real ocean environments or in living organisms.
What the Results Show
The newly identified bacteria, named Jujubicoccus corallicola, is a rod-shaped, gram-negative bacterium that thrives in moderate conditions. It can survive in temperatures ranging from 20 to 37 degrees Celsius (68 to 99 degrees Fahrenheit) and in salt concentrations similar to ocean water. Most importantly, this bacterium can produce vitamin B12 at levels up to 284 micrograms per milliliter of culture medium. This production level is significant because it suggests the bacteria could potentially be used as a biological factory for making vitamin B12 supplements. The genetic analysis showed this is a completely new species that doesn’t match any previously known bacteria, forming its own unique branch on the bacterial family tree.
The bacteria contains specific fatty acids and lipids that are characteristic of ocean-dwelling bacteria. Its genetic material has a composition of 61.3% guanine and cytosine, which is typical for marine bacteria. The bacteria uses a specific type of respiratory system (Q-10 quinone) to generate energy. These characteristics help confirm that this bacterium is well-adapted to living in coral reef environments.
While many bacteria can produce vitamin B12, this particular strain’s ability to produce such high levels (284 µg/ml) is notable. Previous research has identified other vitamin B12-producing bacteria, but finding one in coral that produces at these levels is a new discovery. This adds to our understanding of how coral reef ecosystems support nutrient production through their microbial communities.
This study examined only one bacterial strain in laboratory conditions, not in actual coral or ocean environments. The vitamin B12 production rates were measured in ideal laboratory settings, which may not reflect what happens in nature. The study doesn’t test whether the bacteria actually shares vitamin B12 with the coral or other organisms. Additionally, no human or animal studies were conducted, so we don’t know if this bacteria could be safely used for vitamin B12 production at commercial scales.
The Bottom Line
This is fundamental research with moderate confidence in its findings. The discovery itself is solid and well-documented, but practical applications are still theoretical. Scientists should continue studying this bacteria in more realistic conditions and explore whether it could be used commercially. General consumers should not expect immediate changes to vitamin B12 supplements based on this research.
Marine biologists, microbiologists, and biotechnology researchers should find this discovery interesting for understanding ocean ecosystems and potential industrial applications. People interested in sustainable food production and alternative sources for supplements may find this relevant long-term. This research is not directly applicable to individual health decisions right now.
This is early-stage research. If this bacteria proves useful for commercial vitamin B12 production, it would likely take 5-10 years of additional research and development before any products reach consumers. For now, this is a scientific discovery that opens doors for future research rather than an immediate practical solution.
Frequently Asked Questions
Can this new bacteria be used to make vitamin B12 supplements?
Potentially, but not yet. The bacteria shows promise by producing high levels of vitamin B12 in laboratory conditions. However, researchers need to conduct additional studies on safety, efficiency, and cost-effectiveness before this could become a commercial source for supplements.
Is this bacteria safe for humans to consume?
This study didn’t test safety in humans or animals. Before any supplement could be made from this bacteria, extensive safety testing would be required. Currently, this is purely a laboratory discovery without human applications established.
How does this bacteria help the coral it lives in?
The study identified that the bacteria produces vitamin B12, but it didn’t confirm whether the coral actually uses this vitamin or how they interact. This is an important question for future research to answer.
Why is finding a new vitamin B12-producing bacteria important?
Many bacteria produce vitamin B12, but finding one that produces such high amounts in a sustainable way could eventually provide an alternative to current production methods. This could lead to more environmentally friendly supplement manufacturing in the future.
When will products from this bacteria be available?
This is very early-stage research. If development proceeds, it would likely take 5-10 years of additional research, testing, and regulatory approval before any consumer products could be available. For now, rely on current vitamin B12 sources.
