Diatoms and other chromalveolates are among the dominant phytoplankters in the world's oceans. Endosymbiosis was essential to the success of chromalveolates, and it appears that the ancestral plastid in this group had a red algal origin via an ancient secondary endosymbiosis. However, recent analyses have turned up a handful of nuclear genes in chromalveolates that are of green algal derivation...

Safe drinking water is ahealth necessity. This study was for comparing between certain physico-chemical and microbial parameters of two treatment plants (Shebin El-kom conventional plant Shobrabass compact plant) during a period from February 2019 to December 2019. The treated at these had remarkable enhancement as compared with raw one basically the values TDS, conductivity, total alkalinity, ...

With the advent of modern biotechnology, microorganisms from diverse lineages have been used to produce bio-based feedstocks and bioactive compounds. Many of these compounds are currently commodities of interest, in a variety of markets and their utility warrants investigation into improving their production through strain development. In this review, we address the issue of strain improvement ...

Cadmium, Hg, Pb, and Zn concentrations were determined in 28 species of red, brown, and green algae sampled in the south-western coast of Sardinia (Italy). Elevated concentrations of heavy metals were mainly associated with the presence of smelting activities in the area.

This study analyzed the fatty acids composition and their profile qualitatively quantitatively of nine abundant macroalgal specimens collecting from Egyptian coasts. GC mass analysis identified 23 types, including 13 saturated (SFA) 10 monounsaturated (MUSFA). SFA dominated with 78%, while MUFAs had 22%, UFAs were negligible at 0.01%. MUSFA oleic acid (omega-9) was present in all species except...

Fish-canning wastewater is characterized frequently by a high content of salt (NaCl), making its treatment particularly difficult; however, the knowledge effect NaCl on eukaryotic communities very limited. In present study, global diversity eukaryotes in activated sludges (AS) from 4 different plants (WWTPs) treating fish-canning effluents varying salinity (0.47, 1.36, 1.72 and 12.76 g NaCl/L) ...
