Perspectives for Advancing Biotechnological Succinic Acid Production

open access: yesMicrobial Biotechnology, Volume 19, Issue 5, May 2026.
Succinic acid is an important molecule for sustainable chemical manufacturing, but its industrial production faces high costs and sustainability challenges, which are linked to feedstocks and excessive acid/base consumption. This opinion explores production routes based on next‐generation feedstocks and low‐pH fermentations to inspire novel cost ...

ENERGY-TRANSDUCING PROPERTIES OF PRIMARY PROTON PUMPS RECONSTITUTED INTO ARCHAEAL BIPOLAR LIPID VESICLES [PDF]

open access: yes, 1993
Archaeal lipids differ considerably from eubacterial and eukaryotic lipids in their structure and physical properties. From the membranes of the extreme thermophilic archaea Sulfolobus acidocaldarius a tetraether lipid fraction was isolated, which can ...

Clumped Isotope Temperature Reconstruction Using Stalagmite Drip Cups

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 8, 30 April 2026.
ABSTRACT Rationale Application of clumped isotope palaeothermometry to speleothems (carbonate cave deposits, e.g., stalagmites and flowstones) has been restricted largely to subaqueous samples because of kinetic fractionation processes that occur during subaerial speleothem formation, which lead to erroneously high inferred temperatures.

Photodynamic therapy – hypericin tetraether liposome conjugates and their antitumor and antiangiogenic activity

open access: yesDrug Delivery, 2019
Photodynamic therapy (PDT) is an established noninvasive tumor treatment. The hydrophobic natural occurring pigment hypericin shows a lot of attractive properties for the application in PDT.

Planktonic Lipidome Responses to Aeolian Dust Input in Low-Biomass Oligotrophic Marine Mesocosms

open access: yesFrontiers in Marine Science, 2017
The effect and fate of dry atmospheric deposition on nutrient-starved plankton in the Eastern Mediterranean Sea (EMS; Crete, 2012) was tested by spiking oligotrophic surface seawater mesocosms (3 m3) with Saharan dust (SD; 1.6 g L−1; 23 nmol NOx mg−1; 2 ...

Evaluation of the Dual Impact of Nanotechnologies on Health and Environment Through Alternative Bridging Models

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 15, 17 April 2026.
This review explores how alternative invertebrate and small‐vertebrate models advance the evaluation of nanomaterials across medicine and environmental science. By bridging cellular and organismal levels, these models enable integrated assessment of toxicity, biodistribution, and therapeutic performance.

Origins of archaeal tetraether lipids in sediments: Insights from radiocarbon analysis [PDF]

open access: yesGeochimica et Cosmochimica Acta, 2008
Abstract Understanding the supply and preservation of glycerol dibiphytanyl glycerol tetraethers (GDGTs) in marine sediments helps inform their use in paleoceanography. Compound-specific radiocarbon measurements of sedimentary alkenones from multiple environments have been used to gain insight into processes that affect U 37 K ′

Assessment of soil n-alkane δD and branched tetraether membrane lipid distributions as tools for paleoelevation reconstruction [PDF]

open access: yesBiogeosciences, 2009
δ18O values of pedogenic minerals forming from soil water are commonly used to reconstruct paleoelevation. To circumvent some of the disadvantages of this method, soil n-alkane δD values were recently proposed as a new tool to reconstruct ...

Eukaryotic-Like Virus Budding in Archaea

open access: yesmBio, 2016
Similar to many eukaryotic viruses (and unlike bacteriophages), viruses infecting archaea are often encased in lipid-containing envelopes. However, the mechanisms of their morphogenesis and egress remain unexplored.

Pulsed Electric Fields for Emerging Single‐Cell Bioprocessing in Food Applications: Electropermeabilization Mechanisms and Design Principles

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 2, March 2026.
ABSTRACT This review evaluates pulsed electric fields (PEF) as an emerging platform for single‐cell bioprocessing in food applications. Connections are drawn between key mechanisms in electropermeabilization and applications, and a practical PEF process design framework is provided.
