Molecular Microbiology, Volume 124, Issue 4, Page 297-309, October 2025.The periplasmic multicopper oxidase CueO oxidizes cuprous ions (Cu+) to cupric ions (Cu2+), a well‐known process typically coupled with oxygen reduction. In this study, we report unexpected anaerobic phenotypes associated with CueO, suggesting that it may use an alternative electron acceptor in the absence of oxygen.

Molecular Nutrition &Food Research, Volume 69, Issue 17, September 2025.We have shed light on the mode of action behind the postbiotic form of Bifidobacterium breve NCC 2950. Heat treatment of this strain at 90°C leads to the production of 4‐oxo‐2‐pentenoic acid (OPA), which activates NRF2 host response, improving oxidative stress resistance and decreasing inflammation. ABSTRACT Postbiotics are defined as a “preparation of

Effect of Anaerobiosis on Antimicrobial Susceptibility of Staphylococci [PDF]
Antimicrobial Agents and Chemotherapy, 1977 The minimum inhibitory concentration (MIC) of 12 antibiotics was determined for four strains of staphylococci (representing the three major species) under aerobic and anaerobic conditions by using the broth dilution method. Nine of the antibiotics showed no significant difference between aerobic and anaerobic MIC for any of the four cultures ...

Characteristics of Subgingival Plaque Microbiome in Japanese Older Adults With Healthy Gingiva
Journal of Clinical Periodontology, Volume 52, Issue 9, Page 1314-1326, September 2025.ABSTRACT Aim To elucidate the characteristics of the subgingival plaque microbiome in older adults without gingival inflammation. Materials and Methods Subgingival plaque from 180 participants was collected and analysed using 16S rRNA sequencing. Based on the clinical parameters at the sampling sites, participants were categorised as healthy (gingival ...

Soft-metal(loid)s induce protein aggregation in Escherichia coli
Frontiers in Microbiology, 2023 Metal(loid) salts were used to treat infectious diseases in the past due to their exceptional biocidal properties at low concentrations. However, the mechanism of their toxicity has yet to be fully elucidated.

“Affect of anaerobiosis on the antibiotic susceptibility of H. influenzae” [PDF]
BMC Research Notes, 2013 Background: Haemophilus influenzae is a human-restricted facultative anaerobe which resides mostly in the oropharynx. The majority of isolates recovered from the throat are unencapsulated commensals (NTHi), but depending on host susceptibility they cause bronchitis, otitis media and on occasion bacteremia and meningitis.

Comprehensive Tools for Culturing Blastocystis: A Standardized Resource for Research and Diagnostics
Current Protocols, Volume 5, Issue 8, August 2025.Abstract Blastocystis spp. is a widely prevalent anaerobic protozoan of uncertain pathogenicity found in the gastrointestinal tracts of over 1 billion people worldwide. Despite its potential significance in health and disease, Blastocystis spp. remains challenging to culture axenically due to its anaerobic nature and the diversity of its genetic ...
