ParAquaSeq, a Database of Ecologically Annotated rRNA Sequences Covering Zoosporic Parasites Infecting Aquatic Primary Producers in Natural and Industrial Systems

open access: yesMolecular Ecology Resources, Volume 25, Issue 6, August 2025.
ABSTRACT Amplicon sequencing tools such as metabarcoding are commonly used for thorough characterisation of microbial diversity in natural samples. They mostly rely on the amplification of conserved universal markers, mainly ribosomal genes, allowing the taxonomic assignment of barcodes.

Evaluation of the Spatial Variations in the Biochemical Composition of Seaweed Species Along the Coast of Alexandria, With a Focus on Fatty Acids and Total Amino Acids of the Prevalent Edible Species

open access: yesFood Science &Nutrition, Volume 13, Issue 7, July 2025.
Seaweeds from Alexandra are rich in vitamins E and B3, pigments, and total fatty acids. Ulva linza and Cladophora glomerata were distinguished by their high photosynthetic pigments. Amino acid score of all seaweeds investigated was > 100%. ABSTRACT The biochemical constituents of common seaweed (16 different species) from the coast of Alexandria, Egypt,
