Pyruvate: A key Nutrient in Hypersaline Environments? [PDF]

open access: goldMicroorganisms, 2015
Some of the most commonly occurring but difficult to isolate halophilic prokaryotes, Archaea as well as Bacteria, require or prefer pyruvate as carbon and energy source. The most efficient media for the enumeration and isolation of heterotrophic prokaryotes from natural environments, from freshwater to hypersaline, including the widely used R2A agar ...

Understanding Fungi in Glacial and Hypersaline Environments [PDF]

open access: hybridAnnual Review of Microbiology, 2023
Hypersaline waters and glacial ice are inhospitable environments that have low water activity and high concentrations of osmolytes. They are inhabited by diverse microbial communities, of which extremotolerant and extremophilic fungi are essential components. Some fungi are specialized in only one of these two environments and can thrive in conditions

Culture-Independent Approaches for Studying Viruses from Hypersaline Environments [PDF]

open access: greenApplied and Environmental Microbiology, 2012
ABSTRACT Hypersaline close-to-saturation environments harbor an extremely high concentration of virus-like particles, but the number of haloviruses isolated so far is still very low. Haloviruses can be directly studied from natural samples by using different culture-independent techniques that include transmission electron microscopy, pulsed ...

Preservation of ATP in Hypersaline Environments [PDF]

open access: bronzeApplied and Environmental Microbiology, 1987
High concentrations of particulate ATP were found in the anoxic brines of the Orca Basin and East Flower Garden, Gulf of Mexico. Other measurements indicative of growth and respiration suggested that the microbial community in the brines was inactive, but somehow the ATP associated with the cells persisted.

Biodegradation of petroleum hydrocarbons in hypersaline environments. [PDF]

open access: yesBraz J Microbiol, 2012
Literature on hydrocarbon degradation in extreme hypersaline media presents studies that point to a negative effect of salinity increase on hydrocarbonoclastic activity, while several others report an opposite tendency. Based on information available in the literature, we present a discussion on the reasons that justify these contrary results.

Ergosterol biosynthesis in novel melanized fungi from hypersaline environments [PDF]

open access: hybridJournal of Lipid Research, 2001
Halotolerant and halophilic melanized fungi were recently described in hypersaline waters. A close study of the sterol composition of such fungi, namely Hortaea werneckii, Alternaria alternata, Cladosporium sphaerospermum, Cladosporium sp., and Aureobasidium pullulans revealed the dominance of ergosterol and the presence of 29 intermediates of its ...

Denitrification in hypersaline and coastal environments

open access: yesFEMS Microbiology Letters, 2023
Abstract As the association of denitrification with global warming and nitrogen removal from ecosystems has gained attention in recent decades, numerous studies have examined denitrification rates and the distribution of denitrifiers across different environments.
