2022 article

The microbiome of the pelagic tunicate Dolioletta gegenbauri: A potential link between the grazing and microbial food web

Pereira, T. J., Walters, T. L., El-Shaffey, H. M., Bik, H. M., & Frischer, M. E. (2022, September 4). MOLECULAR ECOLOGY.

By: T. Pereira *, T. Walters *, H. El-Shaffey n, H. Bik * & M. Frischer *

author keywords: 16S rRNA; amplicon sequence variants; ASVs; Dolioletta gegenbauri; doliolid; faecal pellets; microbiome; South Atlantic bight; SAB
TL;DR: Observations support the hypothesis that through their presence and trophic activity, doliolids influence the structure of pelagic food webs and biogeochemical cycling in subtropical continental shelf systems where tunicate blooms are common. (via Semantic Scholar)

An Ionic Liquid Medium Enables Development of a Phosphine-Mediated Amine-Azide Bioconjugation Method

JOURNAL OF THE AMERICAN CHEMICAL SOCIETY, 143(33), 12974–12979.

By: H. El-Shaffey n, E. Gross n , Y. Hall  n & J. Ohata n 

TL;DR: It is demonstrated that an aprotic ionic liquid serves as a novel reaction solvent for protein bioconjugation without noticeable loss of the biomolecule functions. (via Semantic Scholar)
