NewsClove oil yields new Pickering emulsion formulation with enhanced antibacterial properties
Researchers developed a sustainable Pickering emulsion using carbon quantum dots (CQDs), promising solid particles for food applications, derived from clove essential oil residue. They found that CQDs with 40% ethanol demonstrated the highest emulsifying efficacy.

NewsGut bacterium IDed as key player in healing the colon
Researchers have identified Clostridium scindens, a bacterium that converts primary bile acids into 7α-dehydroxylated bile acids, as a key player in gut healing. Supplementing the gut with this bacterium could improve recovery from colonic injury.

NewsCircadian rhythms in tea plant microbiomes shed light on nutrient cycling
A groundbreaking study has uncovered a fascinating connection between the circadian rhythms of tea plants and the microbial communities in their rhizosphere, providing new insights into nutrient cycling.

NewsStudy discovers tuberculosis genes necessary for airborne transmission
Tuberculosis bacteria rely on a family of genes that help them survive the challenging journey from one person’s lungs to another person’s during coughing, sneezing or talking, according to a study that offers new targets for tuberculosis therapies.

NewsMicrobiome: Researchers improve bacterial analysis for clinical applications
Different extraction methods can obtain the DNA of certain bacterial species differently, which can significantly distort the determined microbiome composition. Scientists have developed a computer-based method for correcting extraction bias.

NewsResearch team publishes paradigm-challenging discovery in a Yellowstone thermophile
A graduating PhD student has made an interesting discovery about a common thermophilic bacteria dwelling in hots prings which is able to simultaneously respirate and metabolize via aerobic and anaerobic pathways.

NewsNew discovery and grant to accelerate Strep A vaccine efforts
With a large sum of research funding and multinational contributions, the world’s only Strep A human challenge model will be used to resolve logistical issues and speed up the development of a successful Strep A vaccine.

NewsNovel enzyme found in gut bacteria could revolutionize prebiotic research
Researchers have discovered a new β-galactosidase enzyme in a human gut bacterium that breaks down and synthesizes previously unexplored glycans, which have prebiotic capabilities to improve gut health.

NewsBacteria and minerals work together to detoxify arsenic in contaminated soils
New research shows that the interaction between arsenic-oxidizing bacteria and goethite, a common Fe mineral, significantly accelerates the conversion of arsenic from its highly toxic form, arsenite [As(III)], into the less harmful arsenate [As(V)].

NewsSulfur-reducing bacteria team-up to break down organic substances in the seabed
Researchers have decoded the molecular strategies employed by the underappreciated sulfate-reducing bacteria, <i>Desulfobacteraceae</i>, which is capable of breaking down organic carbon in the oxygen-limited seabed.

NewsPurified immunoglobulin F(ab′) 2 prevents lethal staphylococcal enterotoxin B intoxication in mice and rhesus monkeys
Purified F(ab′)2 fragments are an effective antidote to lethal SEB doses in mice and rhesus monkeys, and therefore might be a favorable candidate for treating patients with severe SEB intoxication, a new study suggests.
-
NewsAntimicrobial resistance in soil bacteria without the use of antibiotics
Overuse of antibiotics is currently the primary reason for the rise of antimicrobial resistance (AMR), but researchers have shown that AMR can be found in soil bacterial communities due to microbial interactions too, driven by a species of predatory bacteria.

NewssiRNA-AGO2 complex inhibits bacterial gene translation: a novel therapeutic strategy for superbug infection
Scientists have demonstrated that exosomes can serve as delivery vehicles to introduce AGO2-loaded siRNA into the cytoplasm of bacteria, and in turn down-regulated gene expression of the mRNA that shares sequence complementarity to the siRNA.
-
NewsBacterial ‘jumping genes’ can target and control chromosome ends
Researchers have discovered a new mechanism that transposons, or “jumping genes” use to survive and propagate in bacteria with linear DNA, with applications in biotechnology and drug development.
-
NewsTB vaccine candidate provides ‘elite’ protection
A tuberculosis vaccine candidate under development shows complete protection and superior immune response in nonhuman primates compared to the existing BCG vaccine.
-
NewsDamaged but not defeated: Bacteria use nano-spearguns to retaliate against attacks
Scientists used state-of-the-art microscopy technology to mimic a nano-speargun, the type VII secretion system, used as a bacterial pinpoint counterattack tactic in response to cell envelope damage against rival bacteria.
-
NewsPackets of freeze-dried bacteria grow biocement on demand
Researchers report a freeze-drying approach that preserves biocement-producing bacteria, potentially allowing construction workers to use powder out of a packet to quickly make tiles, repair oil wells or strengthen the ground for makeshift roads.

NewsThroat microbiome holds clues to older Australians’ health
A simple swab from the back of the throat, known as the oropharynx, may offer clues about health challenges faced by aged care residents.
-
NewsResearchers see breakthrough in efficient biofuel production
Researchers have found ways to limit the toxicity to microbes generated by the biofuel butanol through fermentation of plant biomass, by manipulating the structure of microbe cell membrane at atomic level.
