A High‐Throughput Investigation of the Binding Specificity of Carbohydrate‐Binding Modules for Synthetic and Natural Polymers

ChemSusChem, Volume 18, Issue 16, August 6, 2025.
A high‐throughput screening pipeline is developed to explore the binding specificity of type A carbohydrate‐binding modules (CBMs) to synthetic polymers (polyethylene terephthalate, polystyrene, and polyethylene) and polysaccharides (cellulose, chitin, and starch).

ADP-dependent Phosphofructokinases in Mesophilic and Thermophilic Methanogenic Archaea [PDF]

, 2001
Phosphofructokinase (PFK) is a key enzyme of the glycolytic pathway in all domains of life. Two related PFKs, ATP-dependent and PPi-dependent PFK, have been distinguished in bacteria and eucarya, as well as in some archaea.

Diversity of ThDP‐Dependent Enzymes Forming Chiral Tertiary Alcohols

ChemBioChem, Volume 26, Issue 13, July 11, 2025.
Chiral tertiary alcohols are widespread in nature and bioactive compounds; however, their asymmetric synthesis faces several challenges. This review outlines the toolbox of ThDP‐dependent enzymes able to produce tertiary alcohols through the formation of CC bond formation using ketones as acceptor substrates. Herein, the substrate scope, the diversity

Contrasting Dynamics and Biotic Association Networks in Estuarine Microbenthic Communities Along an Environmental Disturbance Gradient

Environmental DNA, Volume 7, Issue 4, July–August 2025.
Environmental DNA samples were collected across a time series from six estuaries from the Basque coast experiencing different degrees of disturbance. Prokaryotic communities and their association networks differed depending on the disturbance level, being more stable in less impacted estuaries.

THE PURE CULTIVATION OF SPIROCHÆTA DUTTONI, SPIROCHÆTA KOCHI, SPIROCHÆTA OBERMEIERI, AND SPIROCHÆTA NOVYI [PDF]

Journal of Experimental Medicine, 1912
1. A method for the pure cultivation of Spirochœta duttoni, Spirochœta kochi, Spirochœta obermeieri, and Spirochœta novyi is described in this paper. In vitro these strains reach their maximum growth after seven, eight, or nine days at 37°C. For their multiplication they require the presence of a piece of fresh sterile tissue and a body fluid capable ...

THE SURVIVAL OF LEPTOSPIRA (SPIROCHÆTA) ICTEROHÆMORRHAGIÆ IN NATURE; OBSERVATIONS CONCERNING MICROCHEMICAL REACTIONS AND INTERMEDIARY HOSTS

Journal of Experimental Medicine, 1918
1. Leptospira icterohæmorrhagiæ is unable to grow in the urine, either with or without the addition of suitable culture ingredients, the acidity of the urine being detrimental to the growth. It survives less than 24 hours, unless the urine is neutralized

Effects of Natural Polysaccharides on the Gut Microbiota Related to Human Metabolic Health

Molecular Nutrition &Food Research, Volume 69, Issue 11, June 2025.
The graphical abstract illustrates the role of polysaccharides extracted from various natural raw materials (such as mushrooms, marine organisms, fruits, and vegetables) in modulating the gut microbiota. The process begins with the extraction and purification of polysaccharides, followed by assessing their structure‐activity relationship. Upon entering
