A new international study reveals that nitrogen fixation occurs beneath Arctic sea ice, increasing available nitrogen for algae and potentially boosting marine life. This discovery could also impact carbon absorption in the Arctic Ocean.
A team of Georgia Tech biologists discovered that chemoautotrophic sulfur-oxidizing bacteria play a crucial role in providing nitrogen to plants while detoxifying the root zone, enhancing plant health and resilience. This finding highlights the importance of microbes in coastal ecosystems.
Researchers found that the bacterial community in Arctic seabed sediments remains stable throughout the seasons, with changes in gene expression of carbohydrate-degrading enzymes. This suggests that bacteria can utilize fresh material from the water column as well as stored compounds in the seabed.
A team of researchers identified UBA868 as a significant player in the biogeochemical cycle of the deep ocean, regulating energy balance and fixing carbon dioxide. This finding challenges previous assumptions about the role of microorganisms in the marine ecosystem.
A study found that Synechococcus and heterotrophic bacteria have an inherent tendency toward mutualism, which can be re-established after environmental interference. The researchers discovered that the bacteria facilitated nitrogen fixation, converting nitrogen for use in buoying the phytoplankton.
A novel salt-tolerant HN-AD bacterium, Halomonas venusta TJPU05, was isolated and demonstrated excellent potential in treating high-salinity nitrogenous wastewater. The study showed that 86.12% of NH4+-N, 95.68% of NO3––N, 100% of NO2––N and 84.57% of total nitrogen (TN) could be removed from simulated water within 24 hours.
A new study reveals that salt marsh grass in Georgia's coast relies on beneficial bacteria in its roots to access nutrients, improving plant productivity. The research provides insights into the importance of soil microorganisms in maintaining ecosystem health and supporting restoration efforts.
The Verrucomicrobiota group of bacteria plays a crucial role in degrading polysaccharides released by algae during spring blooms in the North Sea. These specialized bacteria consume hard-to-degrade sugars, including those containing sulfate and fucose, using unique pathways and organelle-like structures to avoid toxic compounds.
Researchers from the University of Tsukuba and ETH Zurich found that marine bacteria switch between lifestyles to get the best resources, optimizing nutrient uptake in seascapes of organic particles. Bacteria spend more time on higher-quality patches, fine-tuning their foraging strategy according to patch quality.
Researchers at KAUST studied Red Sea plankton communities, revealing seasonal fluctuations driven by top-down controls like viruses and heterotrophic nanoflagellates. The study provides insight into tropical marine ecosystems, shedding light on the impact of climate change on these vital regions.
Marine bacteria, such as Polaribacter, develop distinct niches with respect to algal polysaccharides, avoiding direct competition. Closely related clades partition available resources through unique sugar utilization strategies.
Researchers created Escherichia coli strains that convert CO2 into biomass, overcoming a major challenge in sustainable production of food and fuels. The study demonstrates the feasibility of transforming a heterotrophic organism into an autotroph using metabolic rewiring and adaptive laboratory evolution.
Researchers found a novel sulfur-oxidizing symbiont, Kentron, which upcycles waste products from its host and environment into biomass. This discovery contradicts traditional descriptions of symbiotic bacteria's carbon sources.
Research suggests that Vibrio species have a crucial role in marine organic carbon cycling, particularly in coastal environments. These bacteria can rapidly consume and transform organic matter into cell material and waste products.
Daily fish migration fuels metabolism of single-celled heterotrophic prokaryotes, revealing a labile DOC source that supports microbial community growth. Higher microbial diversity found in mesopelagic zone than expected.
Researchers at the University of Warwick discovered that phototrophic and heterotrophic bacteria collaborate to cycle nutrients, feeding the ecosystem. This interaction is crucial for maintaining a balanced nutrient level, supporting half of the planet's primary production and oxygen supply.
Researchers from KAUST have developed a model predicting how climate change impacts plankton populations. Temperature, nutrient availability, and mortality rates influence the numbers of heterotrophic planktonic prokaryotes.
Researchers have identified a community of bacteria in wastewater treatment plants that breaks down toxic substances and produces valuable resources. These 'anammox bacteria' can save energy by removing oxygen from the process, making wastewater treatment more efficient and sustainable.
Binghamton University researchers developed a micro-scale self-sustaining bacterial fuel cell that generated power for 13 straight days through symbiotic interactions of two types of bacteria. The cell produced an electrical current about 70 times greater than phototrophic bacteria alone.
Scientists at NREL made a groundbreaking discovery that Clostridium thermocellum can take up and utilize both CO2 and cellulose, counter-intuitive in heterotrophic microbes. This pathway enables the bacterium to use both CO2 and organic carbons during growth.
Fossils from 1,900 million-year-old rocks in Lake Superior's Gunflint chert provide evidence of ancient heterotrophy. The team discovered microbes consumed other bacteria, producing a 'rotten egg' whiff similar to modern bacterial activity.
A study by researchers at Johns Hopkins University School of Medicine found that electronic faucets carry high levels of bacteria, including Legionella spp., compared to traditional manually operated faucets. The findings led to the decision to replace electronic faucets with manual ones in clinical areas.
A Montreal study reveals that more than 70 percent of bottled water samples contain heterotrophic bacteria counts above the recommended limits set by the United States Pharmacopeia. High microbial counts were found in several famous brands, with some exceeding 100 times the permitted limit.
A new study published in the Journal of Environmental Quality examines the health hazards of treated sewage sludge application to land. The risks of aerosol-borne infection for biosolids workers are generally low, at less than 1 or 2% per year.
Researchers develop a bacterial biosensor prototype to detect oxidative stress, which can cause brain tissue damage. The sensor uses potassium release in response to toxins, correlating with cell damage, offering a potential early warning system for public health threats.
