Food Biomacromolecules, Volume 1, Issue 2, Page 58-87, December 2024.Abstract Biopolymers, derived from renewable resources such as plants, animals, and microorganisms, are emerging as sustainable alternatives to traditional petroleum‐based polymers. The review examines the key characteristics of biopolymers, including their biodegradability, biocompatibility, and potential for carbon neutrality.

Purification and biological characterization of halocin H1 from Haloferax mediterranei M2a
International Microbiology, 2002 The production of halocins, bacteriocin-like proteins of ecological significance, is a frequent characteristic of species from the family Halobacteriaceae. Halocin H1, produced by Haloferax mediterranei strain M2a, is a single 31-kDa polypeptide. Its purification was achieved by combining two chromatographic systems: Sepharose 4B linked to bacitracin ...

Autocatalytic maturation of the Tat-dependent halophilic subtilase Nep produced by the archaeon Natrialba magadii [PDF]
, 2012 Halolysins are subtilisin-like extracellular proteases produced by haloarchaea that possess unique protein domains and are salt dependent for structural integrity and functionality. In contrast to bacterial subtilases, thematurationmechanismof halolysins

Understanding the tolerance of halophilic archaea to stress landscapes
Environmental Microbiology Reports, Volume 16, Issue 6, December 2024.The tolerance responses of nine Haloarchaea species were analysed under 70 different conditions, including various salinities, temperatures, oxidative stress and the presence of metals. In general, all characterised species tolerated heavy metals, with a particularly striking tolerance to lithium. These results highlight the relevance of Haloarchaea in

Semi‐continuous non‐sterile production of medium chain‐length polyhydroxyalkanoates from fatty acids
The Canadian Journal of Chemical Engineering, Volume 102, Issue 11, Page 3896-3908, November 2024.Abstract Medium chain‐length polyhydroxyalkanoates (mcl‐PHAs) are efficiently synthesized from fatty acids. It was hypothesized that under non‐axenic conditions, the anti‐microbial properties of fatty acids would reduce growth of microbial competitors and allow Pseudomonas putida LS46 to dominate the population resulting in non‐sterile mcl‐PHA ...

Zeitschrift für Naturforschung C, 1992 Both, Haloferax mediterranei and Haloferax volcanii membranes contain ATPases which are capable of hydrolyzing ATP in presence of Mg2+ or Mn2+. The ATPases require high concentrations of NaCl, a pH value of 9, and high temperatures up to 60 °C. Free manganese ions inhibited the enzyme activity of either ATPase. The ATPases of Hf.

Chirality, Volume 36, Issue 10, October 2024.Bacillus licheniformis AZU‐A5 produced polyhydroxyalkanoates (PHAs) using cheese whey, achieving a yield of 1.75 g L−1 through Plackett–Burman design and specific factor optimization. Spectroscopy, chromatography, and thermal analysis confirmed the PHA as poly(3‐hydroxybutyrate) or P3HB.

Haloarchaea and the Formation of Gas Vesicles
Life, 2015 Halophilic Archaea (Haloarchaea) thrive in salterns containing sodium chloride concentrations up to saturation. Many Haloarchaea possess genes encoding gas vesicles, but only a few species, such as Halobacterium salinarum and Haloferax mediterranei ...

N-glycosylation in the thermoacidophilic archaeon Sulfolobus acidocaldarius involves a short dolichol pyrophosphate carrier [PDF]
, 2016 N-glycosylation is a post-translational modification that occurs across evolution. In the thermoacidophilic archaea Sulfolobus acidocaldarius, glycoproteins are modified by an N-linked tribranched hexasaccharide reminiscent of the N-glycans assembled in ...
