Perchlorate-reducing bacteria from Antarctic marine sediments

Environmental Monitoring and Assessment, 2022
Perchlorate is a contaminant that can persist in groundwater and soil, and is frequently detected in different ecosystems at concentrations relevant to human health. This study isolated and characterised halotolerant bacteria that can potentially perform perchlorate reduction.

Advances in organic UV filters for sunscreens over the past decade

Photochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

Unsaturated Fatty Acids in Antarctic Bacteria

Research Journal of Microbiology, 2016
Unsaturated Fatty Acids (UFAs) play a vital role in membrane lipids fluidity which maintains its structural integrity and also, are nutritionally and pharmaceutically important. Fish and vegetable oils are the major sources of the so-called essential fatty acids required for normal physiological activities of the body.

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

Biological Reviews, Volume 101, Issue 6, Page 2597-2612, December 2026.
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 ...

Property Rights Entrepreneurship: The Drive for Product, Asset, and Resource Excludability

Managerial and Decision Economics, Volume 47, Issue 8, Page 2216-2231, December 2026.
ABSTRACT Property rights are foundational to market economies, and entrepreneurial activity depends heavily on the excludability afforded by property rights. Yet, the role of entrepreneurs in shaping the evolution of property rights has been so thoroughly taken for granted that it often vanishes from analyses.

Antarctic reptant decapods: more than a myth? [PDF]

, 2004
The impoverished Antarctic decapod fauna is one of the most conspicuous biodiversity phenomena in polar science. Although physiological and ecological approaches have tried to explain the reason for the low decapod biodiversity pattern in the Southern ...
