Investigations into the characterization, degradation, and applications of biodegradable polymers by mass spectrometry

open access: yesMass Spectrometry Reviews, Volume 44, Issue 6, Page 947-988, November/December 2025.
Abstract Biodegradable polymers have been getting more and more attention because of their contribution to the plastic pollution environmental issues and to move towards a circular economy. Nevertheless, biodegradable materials still exhibit various disadvantages restraining a widespread use in the market.

The Function of Gas Vesicles in Halophilic Archaea and Bacteria: Theories and Experimental Evidence

open access: yesLife, 2012
A few extremely halophilic Archaea (Halobacterium salinarum, Haloquadratum walsbyi, Haloferax mediterranei, Halorubrum vacuolatum, Halogeometricum borinquense, Haloplanus spp.) possess gas vesicles that bestow buoyancy on the cells. Gas vesicles are also

Small RNAs of Haloferax mediterranei: Identification and Potential Involvement in Nitrogen Metabolism. [PDF]

open access: yesGenes (Basel), 2018
Small RNAs have been studied in detail in domains Bacteria and Eukarya but, in the case of the domain Archaea, the knowledge is scarce and the physiological function of these small RNAs (sRNAs) is still uncertain. To extend the knowledge of sRNAs in the domain Archaea and their possible role in the regulation of the nitrogen assimilation metabolism in ...

Structural adaptation of extreme halophilic proteins through decrease of conserved hydrophobic contact surface [PDF]

open access: yes, 2011
Background: Halophiles are extremophilic microorganisms growing optimally at high salt concentrations. There are two strategies used by halophiles to maintain proper osmotic pressure in their cytoplasm: accumulation of molar concentrations of potassium ...

Study on the correlation between the dominant microflora and the main flavor substances in the fermentation process of cigar tobacco leaves

open access: yesFrontiers in Microbiology, 2023
The flavor of cigar tobacco leaf determines the quality of finished cigar tobacco, and the enhancement of flavor generally relies on microbial fermentation. In this paper, the correlation between the dominant microorganisms and the main flavor substances

FISH, a new tool for in situ preservation of RNA in tissues of deep‐sea mobile fauna

open access: yesLimnology and Oceanography: Methods, Volume 23, Issue 4, Page 273-292, April 2025.
ABSTRACT Accessing the metabolic functioning of deep‐sea animals in situ remains a technological challenge as the recovery time of samples is incompatible with the short lifespan of such molecules as mRNAs. Tools able to preserve RNA in situ exist, but they are incompatible with the study of mobile fauna.
