Ocean Sustainability
Over 70% of the earth is covered in water, which serves as a vital resource human subsistence. Contamination and acidification pose major threats to aquatic health and biodiversity. Microbes offer a promising solution in their ability to breakdown contamination from oil spills and plastics. Applied microbiologists can play a significant part in understanding biodiversity, contributing to solutions, and encouraging stewardship.
What we know and what we need to know about Antarctic marine viruses
Antarctic marine viruses, while proven to be important players in the ecosystem, are not completely understood. In a new paper, researchers aim to fill in the gap between what is known and what is unknown, with a primary focus on RNA viruses, the influence of climate change and their implications.

Climate change may increase the spread of neurotoxin in the oceans
Climate-driven oxygen loss in the Black Sea thousands of years ago triggered the expansion of microorganisms capable of producing the potent neurotoxin methylmercury. That is shown in a new study which suggests that similar processes could occur in today’s warming oceans.
Tiny architects, titanic climate impact: scientists call for coccolithophores to get their own day
Five European research organisations have launched an initiative to make 10 October International Coccolithophore Day, highlighting their crucial role in regulating the planet’s carbon balance, producing oxygen, and sustaining the ocean ecosystems that underpin all life.
Scientists discover regulatory pathway behind cyanobacteria’s carbon-fixing factories
A new study illuminates a key regulatory pathway between cyanobacteria’s light-harvesting systems and the inner compartments where carbon fixation happens, helping us to understand how cyanobacteria balance their energy demands.

Marine heatwaves have hidden impacts on ocean food webs and carbon cycling
A new study analyzing data from robotic floats and plankton records reveals how marine heatwaves reshape ocean food webs and slow transport of carbon to the deep sea.

Volcanic ash may enhance phytoplankton growth in the ocean over 100 km away
A research group has suggested that ash released from volcanic eruptions on Nishinoshima Island led to a temporary surge in phytoplankton levels in the seawater around Mukojima Island, 130 km northeast of Nishinoshima.
Ancient plankton hint at steadier future for ocean life
A team of scientists has uncovered a rare isotope in microscopic fossils, offering fresh evidence that ocean ecosystems may be more resilient than once feared. They analyzed nitrogen isotopes preserved in the shells of tiny plankton called foraminifera.
Do stranded dolphins have Alzheimer’s disease - and how are cyanobacteria involved?
Scientists have come up with an unusual hypothesis: perhaps dolphins become disoriented by suffering from a form of Alzheimer’s disease. It appears that Alzheimer’s-type neuropathology and disorientation may result from chronic exposure to toxic molecules produced by cyanobacteria.
High-latitude phytoplankton particularly sensitive to climate change
A team of researchers have investigated how high-latitude phytoplankton communities responded to ancient climate warming. High-latitude communities are historically understudied and likely to be particularly sensitive to human-driven climate change.
Corals might be adapting to climate change, study shows
Researchers showed that despite a gradual increase in ocean acidity levels over the past 200 years, some corals seem to be able to adjust and continue to generate their hard, stony skeleton structures.
Cell death in microalgae resembles that in humans
For the first time, researchers have observed the same type of programmed cell death in microalgae as in humans. The discovery shows that this central biological process is older than previously thought.
Okinawan marine sponges yield promising treatment for leishmaniasis
A family of compounds called onnamides shows remarkable potential against the parasite that causes a neglected tropical disease.
The role of the microbiome in the successful transplantation of Posidonia oceanica seagrass meadows
A study of seagrass restoration shows that transplantation method directly influences the root microbiome, which is essential for the survival of the plants - paving the way for more effective and sustainable restoration techniques.
Gulf of Aqaba corals survive record-breaking heatwaves, offering hope amid global coral crisis
A new study reveals that corals in the Gulf of Aqaba have withstood four consecutive and intensifying marine heatwaves, including the world’s most extreme 2024 event, without suffering mass bleaching — a resilience unmatched elsewhere.
Coral reefs set to stop growing as climate warms, scientists warn
Most coral reefs will soon stop growing and may begin to erode – and almost all will do so if global warming hits 2°C, according to a new study in the western Atlantic.
New conservation committee led by Applied Microbiology International calls on science community to get on board with microbial conservation
The team behind a new world-leading conservation committee headed by Applied Microbiology International (AMI) is calling on global scientific and conservation communities to get on board to protect microbial life.
Alkali waste dumped in the Pacific Ocean created alkalophilic microbial ecosystems
Barrels filled with industrial waste that were dumped in the sea near Los Angeles more than 50 years ago are creating new microbial ecosystems adapted to highly alkaline conditions.
Extreme diatoms inside the Arctic ice glide into the record books
Diatoms found in polar ice are active until temperatures drop to -15 C - the lowest ever recorded for movement by a eukaryotic cell.
Living ink containing bacteria could help rebuild coral reefs
Researchers created a living material that encourages coral larvae to attach and settle down. Bacterial Reef Ink (BRINK) is a photopolymerized hydrogel hosting two native Hawaiian settlement-inducing bacterial strains.
Ocean warming puts vital marine microbe Prochlorococcus at risk
A new study finds that Prochlorococcus prefers ocean water between 66 and 86 degrees and doesn’t tolerate water much warmer. Climate models predict that subtropical and tropical ocean temperatures will exceed that threshold in the next 75 years.
Coral-inspired pill offers a new window into the hidden world of the gut
Marine corals have evolved intricate, porous structures that shelter diverse microbial communities. Researchers have borrowed this biological blueprint to create an ingestible pill that can sample bacteria from one of the most inaccessible regions of the human body: the small intestine.
Fighting extinction, coral reefs show signs of adapting to warming seas
By studying how six months of elevated ocean temperatures would affect a species of coral from the northern Red Sea, scientists found that although these organisms can certainly survive in conditions that mimic future warming trends, they don’t thrive.
Stress-tolerant corals could help buy time for reefs in a warming world
New research demonstrates how corals that naturally thrive in extreme environments could be used in restoration efforts to protect vulnerable reef systems.
