Transparent Exopolymer Particles (TEP), closely related to the carbon cycle due to their high carbon-to-nitrogen ratio, have become a hot research topic. However, despite the growing interest in this field, there is a lack of comprehensive analysis providing a clear developmental background and quantitative research on the overall trends of TEP studies. To address the gap, this article utilizes VOSviewer and CiteSpace to conduct a bibliometric analysis of TEP research. The results show that the largest contribution of publications in this field is in the United States and it has become an increasingly interdisciplinary research topic. We identify that the current research focus of TEP is mainly on the application of membrane fouling, marine microbial and biogeochemical cycle. In addition, the research focus has shifted from the role of TEP in the marine carbon cycle to its influence on membrane fouling. This study systematically and comprehensively carries out quantitative visualization and analysis of TEP, providing a basis and reference for in-depth understanding of the current status of TEP research as well as grasping the development trend.

A novel, gelatinous, colony-forming, rod-shaped bacterial strain, designated IK01 was isolated from biofilms formed on the membrane surface of a sewage-treating membrane bioreactor (MBR). Strain IK01 produced gelatinous and almost transparent colonies at lower medium concentrations. Fourier transform infrared analysis of the gelatinous colony matrix showed that the matrix could be a biofilm substance.

Marine microorganisms play a critical role in regulating atmospheric CO concentration via the biological carbon pump. Deposition of continental mineral dust on the sea surface increases carbon sequestration but the interaction between minerals and marine microorganisms is not well understood. We discovered that the interaction of clay minerals with dissolved organic matter and a γ-proteobacterium in seawater increases Transparent Exopolymer Particle (TEP) concentration, leading to organoclay floc formation.

Microbial exopolymers are gaining attention as sources for the development of biodegradable materials. Milk kefir, a fermented dairy product produced by a symbiotic community of microorganisms, generates milk kefir grains as a by-product, consisting of the polysaccharide kefiran and proteins. This study develops two materials, one from whole milk kefir grains and another from purified kefiran.
