In-vitro assessment and characterization of anticancer, antibacterial, and antioxidant activity of diatom-derived metabolites

open access: yesScientific Reports
Microalgae are known to produce a spectrum of highly valuable metabolites with substantial nutritional content and pharmacogenetic properties. To explore the antioxidant, antibacterial, as well as anticancer activity of five such microalgal strains ...

A polyphasic method for the characterization of epiphytic diatoms growing on Gelidium corneum

open access: yesMethodsX
Epiphytic diatoms associated with marine macroalgae play vital ecological roles in nutrient cycling and primary production, yet their study remains limited due to the lack of standardized methodologies. This study focuses on diatom communities growing on

Culturing Diatoms

open access: yes, 2023
In this chapter, we provide information on cultures of diatoms, starting with a brief introduction of the history of diatom culture collections. We present a synopsis of diatom strains currently available in culture collections and their representation in terms of habitat diversity, geographical distribution, phylogeny and taxonomic diversity.

The diatom test for drowning: an unreported source of diatom contamination

open access: yesInternational Journal of Legal Medicine
Summary We describe here a previously unreported source of diatom contamination that may prove relevant in routine diatom analysis in suspected drowning cases. Glass microscope slides utilized in the process, during their manufacture, undergo a washing process, after which, diatomaceous earth (kieselguhr, fossil diatoms) is added to avoid ...

Partners or passengers? Revisiting the association between diatoms and aquatic animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Numerous studies have revealed the importance of research on the communities capable of colonizing animal surfaces (epibionts) and the animals on which they live (basibionts). Very few studies have considered epizoic diatoms, and there are gaps and biases in our knowledge, including the choice of basibionts, the methods used, and the habitats ...

Ambident Reactivity in the Phenyl + NO Radical Recombination

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT The recombination reaction of nitric oxide (NO) with radicals via its oxygen atom, rather than the more common nitrogen site, offers an intriguing pathway to the formation of oxynitrenes. The photochemical isomerization of nitroso compounds into their corresponding oxynitrenes may involve such a step.
