Ancient metabolic process recreated: Iron and sulfur reactions in simulated black smokers shed light on early life

The very first cells obtained their energy from geochemical reactions. LMU researchers have now managed to recreate this ancient metabolic process in their laboratory.

Most likely, the earliest ancestor of all life on Earth liked warm conditions, lived off hydrogen, and produced methane. LMU researchers have come to this conclusion based on fossil evidence and metabolic reconstructions using genetic analyses. This relatively simple, primordial acetyl-CoA metabolic pathway has survived in many microorganisms to this day.

To discover more about the metabolism of what were probably among the very first living organisms on Earth, a team of LMU researchers led by Professor William Orsi from the Department of Earth and Environmental Sciences created laboratory simulations of the conditions on young Earth some 4 to 3.6 billion years ago.

These conditions had some similarities to those prevailing today in the hydrothermal vents on the ocean floor known as "black smokers," with a key difference being that the ancient oceans were full of dissolved iron.

Strong growth without any nutrients

In the laboratory experiment, the researchers produced miniature versions of such "black smokers." As it happens naturally at the seafloor, iron and sulfur geochemical reactions took place at high temperatures, forming iron sulfide minerals such as mackinawite (FeS) and greigite (Fe3S4) in a process that produced hydrogen gas (H2).

In these "chemical gardens," the single-celled archaean Methanocaldococcus jannaschii was not only able to thrive, but positively exceeded the expectations of the researchers: "As well as overexpressing some genes of the acetyl-CoA metabolism, the archaeans actually grew exponentially," explains Vanessa Helmbrecht, lead author of the study, which has now been published in the journal Nature Ecology & Evolution.

"At the beginning, we expected only slight growth, as we did not add any extra nutrients, vitamins, or trace metals to the experiment." The single-celled organism thus proved highly adept at utilizing the hydrogen gas produced by the abiotic precipitation of iron sulfides as an energy source.

Isolated from the sediment of hydrothermal vents on the ocean floor, the hyperthermophile microbe Methanocaldococcus jannaschii serves as a model organism for methanogenesis via the Acetyl-CoA metabolic pathway. It is an organism that is adapted to extreme conditions.

"For the cultivation, we were given access to the state-of-the-art facilities in the Archaea Center at the University of Regensburg, where Professor Dina Grohmann and Dr. Robert Reichelt kindly supported us. This was very important for preparing the experiments in the chemical gardens," says Orsi.

Oldest metabolic process in evolutionary history

In the chemical gardens, the cells always remained in direct proximity to the mackinawite particles. This aligns with fossil evidence, where some geological deposits of such minerals from the early history of Earth contain fossil traces of the first microbial life.

The researchers conclude from the study's results that chemical reactions during the precipitation of iron sulfide minerals about 4 billion years ago generated sufficient energy for the survival of the very first cells and thus laid the foundations for the hydrogen-dependent metabolism of the first microbes on young Earth. Accordingly, this form of methanogenesis based on hydrogen produced inorganically through chemical reactions is the oldest known form of energy generation in evolutionary history.

Space—the next frontier

The LMU geobiologists are now asking the question as to whether the metabolic processes they observed might not also take place outside our planet, and therefore whether there could be extraterrestrial habitats for archaeans—such as on Enceladus. NASA already treats this moon of Saturn as a candidate for possible life, because scientists suspect the presence of hydrothermal activities between its rocky core and a liquid "soda ocean" beneath its icy crust.

"In our next study, we will simulate the conditions of Enceladus in the lab and test whether archaeans are capable of surviving and growing there," says Helmbrecht.

Biogas Plant: A Sustainable Solution for Renewable Energy and Waste Management

Introduction

In the face of increasing environmental challenges, the need for clean, renewable energy sources is more critical than ever. A biogas plant presents an innovative solution that addresses both energy production and waste management. By converting organic waste materials into biogas, biogas plants offer a sustainable and eco-friendly alternative to traditional energy sources. In this article, we explore the benefits, working principles, and applications of biogas plants, highlighting their importance in the transition to a greener future.

What is a Biogas Plant?

A biogas plant is a facility that harnesses the natural process of anaerobic digestion to break down organic materials, such as food waste, agricultural residues, and sewage, to produce biogas. This biogas primarily consists of methane (CH4), which can be used as a source of renewable energy for electricity generation, heating, or even as a vehicle fuel. The digestion process takes place in an airtight environment called a digester, where microorganisms break down the organic matter in the absence of oxygen.

How Does a Biogas Plant Work?

Biogas production in a plant involves several key stages:

Feedstock Collection: Organic waste materials, such as crop residues, animal manure, and food waste, are collected and prepared for digestion. The waste is typically shredded to increase the surface area for microbial action.

Anaerobic Digestion: The prepared feedstock is introduced into a digester, where anaerobic bacteria break down the organic matter into biogas. This process occurs in the absence of oxygen and can take several weeks depending on the type of feedstock.

Biogas Collection: The produced biogas is captured and stored in a gas holder. The methane-rich biogas can be processed further for use in various applications.

Digestate: After the digestion process, the remaining material, called digestate, can be used as a nutrient-rich fertilizer for agricultural purposes, completing the waste-to-resource cycle.

Benefits of Biogas Plants

Renewable Energy Generation: Biogas is a clean and renewable energy source that reduces dependence on fossil fuels. By utilizing biogas, biogas plants help decrease greenhouse gas emissions, contributing to a reduction in the overall carbon footprint.

Waste Management: One of the most significant advantages of biogas plants is their ability to process organic waste, which would otherwise end up in landfills. This helps alleviate the growing waste management challenges faced by urban and rural areas worldwide.

Organic Fertilizer Production: The digestate produced by biogas plants is a valuable by-product that can be used as an organic fertilizer. This contributes to sustainable agricultural practices and reduces the need for chemical fertilizers.

Local Economic Development: Biogas plants create local jobs in the areas of construction, operation, and maintenance. They can also support local economies by providing clean energy and agricultural resources.

Energy Independence: By producing biogas locally, communities can reduce their reliance on external energy sources and enhance energy security.

Applications of Biogas Plants

Electricity Generation: Biogas can be used in combined heat and power (CHP) units to generate electricity and heat. This is particularly useful for communities or industries located in rural areas.

Vehicle Fuel: In some cases, biogas is processed into biomethane, a clean alternative to natural gas that can be used as a fuel for vehicles. This application helps reduce transportation emissions.

Home Heating: Biogas plants can provide heating solutions for homes or businesses by converting biogas into thermal energy for space heating or hot water production.

Industrial Applications: Biogas can be utilized in various industrial processes, including food production and chemical manufacturing, to replace conventional energy sources like coal and natural gas.

Types of Biogas Plants

Biogas plants come in various sizes and designs, depending on the scale of operation and the type of feedstock used. The most common types of biogas plants include:

Fixed Dome Biogas Plant: This is a traditional type of biogas plant with a fixed dome structure. It is typically used in small-scale applications, such as rural households and farms.

Floating Drum Biogas Plant: In this design, the biogas is stored in a floating drum that rises and falls with the production of gas. This type of plant is commonly used for both small and medium-scale applications.

Covered Lagoon Biogas Plant: This design involves large open lagoons that are covered to trap the produced biogas. It is typically used for large-scale agricultural operations.

Modular Biogas Plant: These are prefabricated biogas plants designed for easy installation and scaling. They are ideal for industrial use and urban waste management.

Challenges and Considerations

While biogas plants offer numerous benefits, several challenges must be addressed:

Initial Investment: The construction of a biogas plant requires a significant initial investment. However, the long-term benefits, including energy savings and waste management, can offset these costs.

Feedstock Availability: The efficiency of a biogas plant depends on a consistent supply of organic feedstock. Adequate infrastructure for waste collection is crucial to ensuring the plant's success.

Technical Expertise: Biogas plants require skilled operators for optimal performance. Ongoing training and maintenance are necessary to ensure the system runs efficiently.

Conclusion

Biogas plants represent a forward-thinking solution for addressing both energy needs and waste management challenges. By harnessing organic waste to produce renewable energy and valuable by-products like organic fertilizer, biogas plants play a vital role in creating a more sustainable future. With continued investment and technological advancements, biogas energy will increasingly contribute to a cleaner, greener, and more self-sufficient world.
