Effects of Bifidobacterium animalis Subsp. Lactis CP‐9 on Gut Microbiota and Immune Functions in Healthy Infants

Microbial Biotechnology, Volume 19, Issue 8, August 2026.
This study evaluated the 3‐month safety and tolerability of the probiotic CP‐9 in healthy infants aged 6 to 36 months. The research confirmed that, under the conditions of this study, CP‐9 can safely enrich specific beneficial bacterium in the gut without any obvious short‐term safety signal. ABSTRACT Infancy represents a critical period for growth and

Codh/Acs-Deficient Methanogens Are Prevalent in Anaerobic Digesters

Microorganisms, 2021
Methanogens are archaea that grow by producing methane as a catabolic end product and thrive in diverse anaerobic habitats, including soil, sediments, oil reservoirs, digestive tracts, and anaerobic digesters.

In Vivo Enzyme Catalytic Rates in Formate‐Growing Methanococcus maripaludis

Microbial Biotechnology, Volume 19, Issue 7, July 2026.
In vivo catalytic rates of Methanococcus maripaludis enzymes during C1 carbon source limited growth were determined from metabolic model estimated fluxes and proteomics data. They showed weak agreement with turnover numbers predicted from sequences.

Homoacetogenic Conversion of Mannitol by the Thermophilic Acetogenic Bacterium Thermoanaerobacter kivui Requires External CO2

Frontiers in Microbiology, 2020
Acetogenic microorganisms utilize organic substrates such as sugars in addition to hydrogen (H2) + carbon dioxide (CO2). Recently, we reported that the thermophilic acetogenic microorganism Thermoanaerobacter kivui is among the few acetogens that utilize

Epigenetic Perspectives on Maternal Gut Microbiota's Impact on Embryonic and Fetal Development

Comprehensive Physiology, Volume 16, Issue 3, June 2026.
This review summarizes how maternal health and nutrition shape gut microbiota via epigenetics to regulate embryonic development. It highlights microbiota‐embryo interactions, disruption by prenatal chemical exposures, and personalized nutrition for disease prevention, offering novel insights and therapeutic targets.

Microbial Ecology of the Heterogeneous Terrestrial Deep Biosphere Over 4 years in the Deep Mine Microbial Observatory (DeMMO)

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract The deep continental subsurface hosts a large, diverse, and poorly characterized microbiome. The geochemistry and microbiology of deep subsurface sites are closely linked and influenced by geological, hydrological, and anthropogenic factors. The Deep Mine Microbial Observatory (DeMMO; Lead, SD) was established in 2015 to provide stable portals

Molecular evolution of the Wood-Ljungdahl pathway and the reductive glycine pathway in Thermodesulfobacteriota

Abstract Carbon fixation is a fundamental metabolic process that sustains ecosystems, yet its origins and evolutionary history remain largely unresolved. In this study, we focused on the Wood-Ljungdahl (WL) pathway, which is considered one of the most ancient carbon fixation pathways and the reductive glycine (rGly) pathway, which ...

Mitigating methane emissions and promoting acetogenesis in ruminant livestock

Frontiers in Animal Science
Through enteric fermentation, ruminants convert fibrous biomass into high-quality proteins like meat and milk. In this process however, methanogenic archaea in the ruminant gastrointestinal tract produce methane, a potent greenhouse gas, from the by ...
