Researchers at the University of Toronto have developed a novel biofiltration technique that uses bacteria to eliminate odors from pulp mill gas streams. The new technology operates at higher temperatures than existing methods, making it more cost-effective and environmentally friendly.
Research by astrobiologist Jack Farmer highlights the significance of microbial ecosystems found in hydrothermal environments, which could be cradles for life on other planets. Discoveries of new forms of life on Earth thrive in extreme environments broaden possibilities for similar life to exist elsewhere.
Researchers at University of Illinois used polymerase chain reaction to detect microbes in water, rock, and air samples from hot springs. They found evidence of life in new springs, suggesting microbes may have been transported by wind-borne steam or existing waters.
A new archaeon, Ferroplasma acidarmanus, is found in mining sites and accelerates the production of sulfuric acid, a major environmental pollutant. The microbe's ability to thrive in acidic conditions without a cell wall defies conventional understanding.
Researchers at the University of Washington found a strong correlation between the diversity of plants, algae, and bacteria in an ecosystem. The study suggests that altering biodiversity can have far-reaching effects on the entire food chain.
Researchers investigate microorganisms found in Siberia's permafrost, glaciers, and polar ice caps, which could hold clues to life on Mars. The study aims to develop techniques for exploring icy worlds and understanding the potential for life beyond Earth.
A team of researchers has discovered the largest bacteria ever known, Thiomargarita namibiensis, which stores elemental sulfur and nitrate. The finding provides firmer evidence of coupling between the sulfur and nitrogen cycles in the ocean, offering new insights into the environment's recycling processes.
Russian scientists are developing a bacterial mixture to break down organic waste from astronauts' underwear, reducing storage issues in space. The disposal unit will process plastic, cellulose, and other waste aboard spacecraft, addressing the acute problem of waste management in space.
According to Bruce Rittmann, microbes can break down a wide variety of pollutants, including PCBs and chlorinated solvents, through processes such as in situ bioremediation. In these processes, microbes are fed oxygen and nutrients to stimulate their growth and degradation of contaminants.
