Scum of the Earth: A Hypothesis for Prebiotic Multi-Compartmentalised Environments

Life, 2021
Compartmentalisation by bioenergetic membranes is a universal feature of life. The eventual compartmentalisation of prebiotic systems is therefore often argued to comprise a key step during the origin of life.

Prebiotic Chemistry: The Role of Trimetaphosphate in Prebiotic Chemical Evolution

Frontiers in Chemistry, 2022
Life’s origins have always been a scientific puzzle. Understanding the production of biomolecules is crucial for understanding the evolution of life on Earth. Numerous studies on trimetaphosphate have been conducted in the field of prebiotic chemistry.

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

Advanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

Prebiotic Activity Score of Rice Analogue Containing Porang (Amorphophallus onchophyllus) Glucomannan for Bifidobacterium longum FNCC 0210 and Lactobacillus acidophilus FNCC 0051

Indonesian Food and Nutrition Progress
Glucomannan from the porang tuber (Amorphophallus oncophyllus) was reported to have a prebiotic effect. The prebiotic effect of porang glucomannan used in a rice analog has never been studied.

Enhancing Broiler Growth Performance and Gut Health: A Comparative Study on the Impact of Probiotics, Prebiotics, and Pomegranate (Punica granatum L.) Peel Powder [PDF]

Brazilian Journal of Poultry Science
A total of 200 one-day-old Ross 308 male broilers were randomly assigned to 4 treatments and 5 replicates in a completely randomized design to assess growth performance, serum biochemicals, and intestinal characteristics for 42 days. Treatments comprised

Oral Nanomicelle‐Mediated Sequential Butyrate Production in the Intestine for Ulcerative Colitis and Immunosuppression Treatment

Advanced Science, EarlyView.
After oral administration, inodorous GLU‐BA self‐assembles into nanomicelles in aqueous environments to resist premature gastric adsorption. Upon reaching the intestine, endogenous esterases rapidly cleave the built‐in ester bonds in these nanomicelles to release BA and GLU, with GLU further metabolized by gut microbiota to gradually generate BA ...

Oligosaccharides With Defined Glycosidic Bonds Shape Gut Microbial Succession and Metabolism Via Bond‐Specific Microbial Responders

Advanced Science, EarlyView.
Oligosaccharides with defined glycosidic bonds drive divergent gut microbial succession and shape unique metabolic profiles. Absolute time‐series profiling with Bayesian generalized Lotka–Volterra modeling identifies bond‐specific microbial responders, while monoculture validation and metaproteomics reveal linkage‐matched transport and cleavage modules.

A plausible pathway to prebiotic peptides via amino acid amides on the primordial Earth

Earth and Planetary Physics
The prebiotic synthesis of peptides prior to ribosome-catalyzed processes remains an enigma. The synthesis of abiotic peptides from amino acids (AAs) is primarily constrained by high activation energies and unfavorable thermodynamics, necessitating the ...

Prebiotic effects: metabolic and health benefits [PDF]

, 2010
The different compartments of the gastrointestinal tract are inhabited by populations of micro-organisms. By far the most important predominant populations are in the colon where a true symbiosis with the host exists that is a key for well-being and ...
