Nature‐Inspired Uv Filters: Synthetic Mycosporine‐Like Amino Acids and Gadusol Analogs for Enhanced Photoprotective and Antioxidant Performance

open access: yesChemPhotoChem, EarlyView.
Photoprotection is a current and relevant topic; therefore, the development of new sunscreens is necessary. To this end, nature is examined for molecules such as mycosporine‐like amino acids and gadusol. Through rational design, this study has successfully synthesized new UV filters and evaluated their photoprotective and antioxidant properties ...

Co-encapsulation of Daphnia magna and microalgae in silica matrices, a stepping stone toward a portable microcosm [PDF]

open access: yes, 2014
We report on the first silica encapsulation of a metazoan (Daphnia magna), with a high initial viability (96% of the population remained active 48 h after encapsulation).

Synthesis of N‐Substituted Pyrrole‐2,5‐Dicarboxylic Acids from d‐Galactaric Acid

open access: yesChemSusChem, EarlyView.
Straightforward synthesis route to N‐substituted pyrrole‐2,5‐dicarboxylic acids. Starting from biobased d‐galactaric acid. Up to 45% yield. R = alkyl, benzyl, aryl. Pyrrole‐2,5‐dicarboxylic acid (PDCA) and its N‐substituted derivatives are interesting building blocks for macromolecular applications. However, only a few published procedures describe the

Influence of environment and mineralogy on euendolithic microboring patterns

open access: yesThe Depositional Record, EarlyView.
Field experiments at Little Ambergris Cay reveal that euendolithic microorganisms preferentially bore carbonate substrates based on mineralogy, sea water saturation and trace metal content. Results highlight night‐time dissolution activity and mineralogical preferences, shedding light on the ecological and evolutionary drivers of bioerosion and their ...

Effects of phytoplankton species distribution on particulate organic carbon dynamics along a coastal gradient

open access: yesEcography, EarlyView.
Phytoplankton communities affect carbon dynamics worldwide, strongly influencing the quality and quantity of organic carbon in coastal ecosystems. Yet, we still know little about the impacts of changing phytoplankton community composition on the potential carbon pathways in estuaries and coasts.

Bio‐Based Solvents Extraction and Enzyme‐assisted Recovery of Furan Fatty Acid From Ammonia‐Stabilized Hevea Latex

open access: yesEuropean Journal of Lipid Science and Technology, EarlyView.
The latex of Hevea brasiliensis is rich in furan fatty acid (FuFA) esterified in both neutral and polar lipids. Bio‐based solvents to extract FuFA from ammonia‐stabilized latex was tested. Ethyl acetate worked best, especially with low‐ammonia content. Isopropanol was a good alternative. Lipases could also help to efficiently release FuFA. The findings

Biochemical characteristics and applications of microalga Chlorella sorokiniana KNUA228 isolated from Ulleungdo

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract The increasing environmental and health challenges posed by fossil fuel dependency necessitate the exploration of renewable bioresources. Chlorella sorokiniana KNUA228, a microalga isolated from Ulleungdo, Republic of Korea, was investigated to evaluate its biotechnological potential. Molecular analyses confirmed its identity as C. sorokiniana,
