NewsMarine-inspired sunscreen ingredient made by E. coli
Researchers have engineered microbial “cell factories” to sustainably produce the UV-protective compound gadusol, which could eventually serve as a sunscreen ingredient and an antioxidant additive. Gadusol, found in the eggs of various fish and other marine organisms, helps protect against ultraviolet damage.

NewsResearchers develop microalgae that photosynthetically produce and secrete biofuel precursors
A research group has developed cyanobacterial strains that produce free fatty acids (FFAs) and secrete them into the culture medium. FFAs are important precursor materials for sustainable aviation fuel and diesel fuel alternatives.

NewsNew reactor design produces renewable methane from carbon dioxide
A new reactor design efficiently converts carbon dioxide and renewable electricity into methane while scaling the system up by roughly an order of magnitude. It demonstrated that microbial electrosynthesis systems can be expanded beyond laboratory-scale devices while maintaining high energy efficiency and methane production rates.

NewsResearchers develop next-generation CRISPR biocontainment technology for controlling microbial survival without DNA cleavage
Researchers have employed a CRISPR-dCas9-based base editing system capable of introducing precise nucleotide changes without inducing DNA double-strand breaks. The researchers targeted the start codons of essential genes and irreversibly disrupted their function, permanently blocking cell survival.

NewsWith large DNA fragment assembly, scientists can design microbes that produce countless complex products
A review demonstrates that scientists can now reliably build and combine very large pieces of DNA, making it much easier to redesign microbes such as yeast and bacteria to act as efficient “cell factories.”

NewsA universal toolkit for editing bacterial DNA
A major collaboration involving nine labs has transferred a particularly useful DNA editing system from E. coli into 14 new species of bacteria, spanning three major branches of the bacterial family tree.

NewsHow AI can help us count the ‘good’ viruses used in biopharmaceuticals
Researchers have developed a new methodology that uses artificial intelligence (AI) tools to identify and count target viruses more efficiently than previous techniques. The new approach can be used in applications such as pharmaceutical biomanufacturing.

NewsHot spring microbiomes could transform industrial CO2 waste into valuable products
Researchers found that microbiomes inhabiting terrestrial hot springs are naturally adapted to conditions that closely resemble industrial waste streams: high temperatures, elevated concentrations of CO2, and chemically challenging environments.

NewsResearchers uncover a ‘treasure trove’ of bioactive molecules in coral reefs
Researchers have found that coral reefs are home to a vast array of previously unknown bioactive metabolites — small biomolecules that have the biotechnological potential to provide the basis for new drugs, and a host of other products.

NewsEngineered enzyme breakthrough offers sustainable solution for polyurethane plastic recycling
A research team has elucidated, for the first time, the catalytic mechanism by which the esterase Aes72 hydrolyzes urethane bonds in polyurethane (PU), and by engineering the enzyme to further enhance its catalytic efficiency.
-
NewsSoil bacteria break down toxic chemicals in the environment
Soil bacteria can help to break toxic aromatic compounds down. For one of these, Rhodococcus opacus 1CP, researchers have analyzed the genome and identified many potential metabolic pathways that the bacterium can employ to act as a ‘clean-up specialist’.

NewsBiosensor detects early fungal outbreaks, advances plant biotechnology
A new biosensor detects the emerging presence of fungus on plants at the molecular level, paving the way for next-generation crop protection and the development of stress-tolerant plants.

NewsScientists reveal valuable secrets of Pacific coral reefs
An international consortium of scientists has uncovered new insights into coral ecosystems, revealing that different coral species host their own distinct communities of microbes. They show that coral reefs harbour diverse microbes and produce chemicals with promising potential.

NewsDiversification of termite diets was made possible by genome modifications
Study reveals that evolutionary divergence occurred before ecological divergence, enabling these insects to feed on both wood and soil. Future discoveries may be applied to the production of biofuels.

NewsBreadcrumbs lead to fossil free production of everyday goods
The humble breadcrumb could hold the key to cutting out fossil fuels from one of the chemical industry’s most widely used reactions. Scientists have found a one-pot microbial formula that uses waste bread to replace fossil fuel-derived hydrogen in hydrogenation.

NewsRhododendron-derived drugs now made by bacteria
Bioengineered E. coli bacteria can now produce a group of compounds with anticancer, anti-HIV, antidiabetic and anti-inflammatory activities. The compounds, orsellinic acid-derived meroterpenoids, are produced by Rhododendron species.

NewsHow the joint defence mechanism of two bacteria works
Back in 2021, researchers showed that bacteria of the genera Pseudomonas and Paenibacillus join forces to protect themselves from their predator, an amoeba. Now, they have been able to show exactly how this defense mechanism works.

NewsA standout solvent for today’s biorefineries
Researchers tested multiple distillable amine-based solvents to see how they performed in pretreatment processes for biomass. They found butylamine was a superior solvent.

NewsTaxiing through the gut: Formic acid in the microbiome
Scientists have found that the gut bacterium Blautia luti produces formic acid (formate) instead of carbon dioxide (CO₂) and hydrogen, with hydrogen bound to CO₂. In this case, formic acid is the electron taxi, allowing the energetically costly production of hydrogen to be bypassed.
