- It delves into mechanisms of adsorption, influences on technology performance, and offers future research directions aimed at improving microbial fluoride removal methods.
Article Abstract
Fluoride is an essential trace element for the human body, but excessive fluoride can cause serious environmental and health problems. Therefore, developing efficient fluoride removal technologies is crucial. This review summarizes the progress made in using microbial materials to remove fluoride from wastewater, covering strategies that involve pure cultures of bacteria, fungi, and algae, as well as modified microbial materials and bioreactors. Live microorganisms exhibit high efficiency in adsorbing low concentrations of fluoride, while modified microbial materials are more suitable for treating high concentrations of fluoride. The review discusses the adsorption mechanisms and influencing factors of these technologies, and evaluates their practical application potential through techno-economic analysis. Finally, future research directions are proposed, including the optimization of modification technologies and the selection of effective microbial species, providing theoretical guidance and a basis for future microbial defluoridation technologies.

Catechol-functionalized proteins in mussel holdfasts are essential for underwater adhesion and cohesion and have inspired countless synthetic polymeric materials and devices. However, as catechols are prone to oxidation, long-term performance and stability of these inventions awaits effective antioxidation strategies. In mussels, catechol-mediated interactions are stabilized by 'built-in' homeostatic redox reservoirs that restore catechols oxidized to quinones.

Characterizing the dynamics of microbial community succession in the infant gut microbiome is crucial for understanding child health and development, but no normative model currently exists. Here, we estimate child age using gut microbial taxonomic relative abundances from metagenomes, with high temporal resolution (±3 months) for the first 1.5 years of life.

Objective: To evaluate the effect of the toothpaste containing ε-poly-L-lysine (ε-PL) and funme peptide (FP) as key components on oral microbial composition and oral health.
Methods: An oral microbiome study was initially carried out to analyze the variation in the oral microbiota before and after use of antimicrobial peptide (AMP) toothpaste. Subsequently, a clinical trial was independently performed to assess the efficacy of AMP toothpaste by measuring the dental plaque index (PLI), volatile sulfur compounds (VSCs) levels, modified bleeding index (mBI), and bleeding on probing rate (BOP%).
