Red and purple microbes give Australia’s mysterious pink lake its hue

Pink Australian lake gets its color from red & purple microbes. DNA sequencing has revealed that a bright pink lake on an island off Western #Australia gets its color from a mix of salt-loving #bacteria & algae. #microbiology #environment Read more at: https://www.newscientist.com/article/2311507-red-and-purple-microbes-give-australias-mysterious-pink-lake-its-hue/

Within an Antarctic sea squirt, scientists discover bacteria with promising anti-melanoma properties

Scientists identify a bacterial species that resides within Synoicum adareanum (a species of ascidian common to the waters of Antarctica's Anvers Island archipelago) and that produces a melanoma-fighting compound called palmerolide A. #microbiology #environment #symbiosis #bacteriology #cancer There are few places farther from your medicine cabinet than the tissues of an ascidian, or "sea squirt," on the icy Antarctic sea floor—but this is precisely where scientists are looki

Prokaryotic Diversity and Composition Within Equatorial Lakes Olbolosat and Oloiden in Kenya, Africa

Symbionts sans frontieres: Bacterial partners travel the world

Symbionts sans frontieres: Bacterial partners travel the world #symbiosis #microbiology #environment This pandemic year has restricted international travel for humans. Not so for some microscopic bacteria in the ocean: They partner up with clams living in the sand beneath the shimmering waters of coastal habitats throughout the globe. According to research by scientists from the Max Planck Institute for Marine Microbiology in Bremen and the University of Vienna now published

Microbes in ocean help moderate Earth's temperature

#microbiology #microbiome #environment #climate #climatechange A lot of methane is found beneath seafloor, yet very little leaves oceans & gets into atmosphere. Researchers now discover that microbes rapidly consume the methane, preventing its escape into Earth's atmosphere. Methane is a strong greenhouse gas that plays a key role in Earth's climate. Anytime we use natural gas, whether we light up our kitchen stove or barbeque, we are using methane. Only three sources on Eart

Researchers study the gut microbiome of bees

#microbiome #microbiota #bee #bees #environment As expected, core bacteria accounted for up to 98% of total bacteria. But the small remaining portion included 164 operational taxonomic units of bacteria & 118 of fungi, compared to just 32 from the core species. Environmental bacteria and fungi that end up in the belly of honeybees may be essential to their survival in a changing world as bee populations dwindle due to pesticides, poor nutrition, habitat destruction and declin

An unusual symbiosis of a ciliate, green alga, and a previously unknown purple bacterium.

#microbiology #symbiosis #environment Researchers discovered that the endosymbiotic bacterium belongs to "purple sulfur bacteria" but has lost the ability to oxidize reduced sulfur compounds. Dr. Sebastian Hess and his team at the University of Cologne's Institute of Zoology have studied a very rare and puzzling tripartite symbiosis. This consortium consists of a ciliate as host and two types of endosymbionts: A green alga and a previously unknown purple bacterium. Through ge

A few common bacteria account for majority of carbon use in soil

#microbiology #soil #soils #ecology #environment Just a few bacterial taxa found in ecosystems across the planet are responsible for more than half of carbon cycling in soils. These new findings, made by researchers at Northern Arizona University and published in Nature Communications this week, suggest that despite the diversity of microbial taxa found in wild soils gathered from four different ecosystems, only three to six groups of bacteria common among these ecosystems we

Aspergillus flavus occurrence and aflatoxin B1 contamination associated with peanut

#microbiology #mycology #Aspergillus #microbiota #environment #agriculture #fungi #food #soil Aflatoxin B1 is a strong carcinogenic and toxic fungal toxin produced by Aspergillus flavus and other Aspergillus species, and can seriously threaten the health of consumers and the safety and quality of agricultural products. Aspergillus in agricultural products are closely related to topography and symbiotic microbes. It is not fully clear that how topography affects the assembly p

Scientists discover function of microbes living in oysters

#microbiome #microbiota #oysters #environment #marine Scientists from the University of Rhode Island have taken the first steps toward understanding the function of microbes that live on and in Eastern oysters, which may have implications for oyster health and the management of oyster reefs and aquaculture facilities. "Marine invertebrates like oysters, corals and sponges have a very active microbiome that could potentially play a role in the function of the organism itself,"

Environmental antibiotics and resistance genes as emerging contaminants

#bioremediation #environment #microbiology #antibiotics #AntibioticResistance In developing countries, the use of antibiotics has helped to reduce the mortality rate by minimizing the deaths caused by pathogenic infections, but the costs of antibiotic contamination remain a major concern. Antibiotics are released into the environment, creating a complicated environmental problem. Antibiotics are used in human, livestock and agriculture, contributing to its escalation in the e

"Introduction" by David Ojcius and Nicolas Renard to Special Issue: "Reinventing Plastics"

#plastics #plasticpollution #plastic #pollution #environment Plastics are yesterday’s hero and today’s villain – their fall from grace precipitated by their success. As with many materials, plastics were perfectly acceptable as long as their use remained marginal. But now that plastics have conquered the planet, their use has become a problem. After cement and steel, plastics are the third most-widely manufactured material in the world. And production of plastics will c

Climate-friendly microbes recycle carbon without making methane.

#microbiology #environment #climate #archaea Researchers identify an entirely new phylum of archaea (which they named Brockarchaeota) in hot springs in China & deep-sea hydrothermal vents in the Gulf of California. Earth’s hot springs and hydrothermal vents are home to a previously unidentified group of archaea. And, unlike similar tiny, single-celled organisms that live deep in sediments and munch on decaying plant matter, these archaea don’t produce the climate-warming gas

Microbes are ‘unknown unknowns’ despite being vital to all life, says study

#microbiology #environment #health A new study has highlighted how little is known about microbes – the hidden majority of life on Earth. Life on the planet relies on an enormous quantity of bacteria, fungi and other tiny organisms. They generate oxygen, keep soils healthy and regulate the climate. Microbes play a crucial role in food production, such as cheese, beer, yoghurt and bread. But despite their importance to human life and the health of the Earth, a new scientific p
