Role of Polyphosphates in Microbial Adaptation to Extreme Environments
(American Society for Microbiology, 2008-10)
Anthropomorphically, an extreme environment is one in which physical conditions are not conducive for human life. In this review, extreme environments are defined as habitats that experience steady or fluctuating exposure ...
Fungal Endophytes Enhance the Photoprotective Mechanisms and Photochemical Efficiency in the Antarctic Colobanthus quitensis (Kunth) Bartl. Exposed to UV-B Radiation
(FRONTIERS MEDIA SA, 2020)
Antarctic plants have developed mechanisms to deal with one or more adverse factors which allow them to successfully survive such extreme environment. Certain effective mechanisms to face adverse stress factors can arise ...
Occurrence of Resistance to Antibiotics, UV-B, and Arsenic in Bacteria Isolated from Extreme Environments in High-Altitude (Above 4400 m) Andean Wetlands
(Springer, 2008-05)
High-altitude Andean wetlands are pristine environments with extreme conditions such as high UV radiation, high heavy metal content (mainly arsenic), high salinity, and oligotrophy. In this paper, the UV-B resistance and ...
Genomic and phenotypic attributes of novel salinivibrios from stromatolites, sediment and water from a high altitude lake
(BioMed Central, 2014-06)
Background: Salinivibrios are moderately halophilic bacteria found in salted meats, brines and hypersaline environments. We obtained three novel conspecific Salinivibrio strains closely related to S. costicola, from Socompa ...
Developmental reprogramming by UV-B radiation in plants
(Elsevier Ireland, 2017-11)
Plants are extremely plastic organisms with the ability to adapt and respond to the changing environmental conditions surrounding them. Sunlight is one of the main resources for plants, both as a primary energy source for ...
UV-resistant Acinetobacter sp. isolates from Andean wetlands display high catalase activity
(Wiley Blackwell Publishing, Inc, 2011-04)
Andean wetlands are characterized by their extreme environmental conditions such as high UV radiation, elevated heavy metal content and salinity. We present here the first study on UV tolerance and antioxidant defense of ...
Estimación del índice UV mediante la modelación TUV en el Área Metropolitana de Huancayo durante los años 2005 a 2019
(Universidad Peruana UniónPEPE, 2021-05-24)
The ultraviolet radiation (UV) Index was estimated for the years 2005 to 2019 from the Metropolitan Area of Huancayo, Junín-Peru. For these, solar ultraviolet (UV) index from Ozone Monitoring Instrument (OMI) and Tropospheric ...
Analise da radiação UV-B durante os eventos de influência do buraco de ozônio antártico na região sul do Brasil
(Universidade Federal de Santa MariaBrasilMeteorologiaUFSMPrograma de Pós-Graduação em MeteorologiaCentro de Ciências Naturais e Exatas, 2022-05-13)
Exposure to the sun is fundamental for human health and the growth and development of f lora and fauna, although excessive exposure to the sun’s UV rays can be harmful to all living things. It can affect aquatic and ...
Effects of UV radiation on aquatic ecosystems and interactions with other environmental factors
(Royal Society of Chemistry, 2015-01)
Interactions between climate change and UV radiation are having strong effects on aquatic ecosystems due to feedback between temperature, UV radiation, and greenhouse gas concentration. Higher air temperatures and incoming ...
