Microbes Found Thriving in Extreme Ocean Mud Volcanoes with pH 12
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Scientists have discovered microbial life surviving in newly identified mud volcanoes with extremely high pH levels of 12, expanding our understanding of how life can adapt to Earth’s most hostile environments.
📈 One key stat: Microbes were found thriving in environments with pH levels of 12, one of the toughest challenges ever recorded for deep-sea ecosystems.
💬 One key quote: “What is fascinating about these findings is that life under these extreme conditions, such as high pH and low organic carbon concentrations, is even possible. Until now, the presence of methane-producing microorganisms in this system has been presumed, but could not be directly confirmed.”
1️⃣ The big picture: Scientists from the University of Bremen have discovered microbial life in two newly identified mud volcanoes with extremely high pH conditions of 12. The team used lipid biomarker analysis to identify how microorganisms survive in these incredibly harsh deep-sea environments. Unlike typical ocean microbes that process carbon from above, these communities extract energy from minerals in surrounding rocks and gases like carbon dioxide and hydrogen. This discovery provides valuable insights into the extreme limits where life can exist on our planet, and potentially offers clues about how early life might have originated.
2️⃣ Why is this good news: This discovery significantly expands our understanding of life’s adaptability to extreme environments. The microbes found in these hostile conditions use innovative strategies to survive, drawing energy from rocks and gases rather than traditional nutrient sources. Their existence in such harsh settings may provide crucial clues about how life originally developed on Earth and could inform theories about where life might exist beyond our planet. Additionally, studying these unique organisms can lead to new insights about microbial metabolism and adaptation, potentially inspiring biotechnology applications or helping scientists understand how life might persist through environmental changes.
3️⃣ What’s next: Palash Kumawat and his research team plan to cultivate these organisms in an incubator to learn more about their nutrient preferences in inhospitable environments. Further research can reveal additional details about how these microbes survive and the specific mechanisms they use to extract energy from minerals. The findings may also help scientists develop better techniques for detecting life in other extreme environments on Earth or beyond.
