The Diversity of Bacterial Chemosensing

2018
Bacteria have a continuous and urgent need to inform themselves about the chemistry of their surroundings. They must rapidly adjust their patterns of gene expression, their metabolic and transport functions, and their behavior to cope with every challenge and opportunity with which they are presented.

Bacterial Diversity at High Temperature

1976
An increasing number of organisms which are able to grow at high temperature has been isolated during the last few years.Our purpose in this paper is to analyze their properties from a microbiological point of view. The discussion will only deal with thermophilic procaryotes to the exclusion of blue-green algae (Castenholz, 1969) and actinomycetes ...

Bacterial and Archaeal Diversity in Permafrost

2008
Microorganisms in permafrost survive in an extreme environment characterized by constant subzero temperatures, low water and nutrient availability, and prolonged exposure to background radiation. Despite the harsh conditions, considerable abundance and diversity of microorganisms inhabit permafrost.

Structural Diversity of Bacterial Volatiles

2020
Bacterial volatile organic compounds (VOCs) represent a structurally very broad mixture of compounds, likely not less diverse than plant or animal volatiles. Within this diversity individual compounds might be commonly found in many, often unrelated strains, while others are restricted to a certain group of strains.

Diversity of bacterial iron mineralization

Earth-Science Reviews, 1998
Abstract Bacterial cells, growing naturally in freshwater and marine environments or experimentally in culture, can precipitate a variety of authigenic iron minerals. With the vast majority of bacteria biomineralization is a two-step process: initially metals are electrostatically bound to the anionic surfaces of the cell wall and surrounding organic

Diversity of Cyano-Bacterial Mats

2003
Sustainable existence of biotic systems depends on their fitness to environment, which means minimal changes caused by their activity in habitat. Otherwise changed environment will call to existence another biocoenosis fitted to it, as it occurs during succession.

Evolution of bacterial denitrification and denitrifier diversity

Antonie van Leeuwenhoek, 1983
Little is known about the role of nitrate in evolution of bacterial energy-generating mechanisms. Denitrifying bacteria are commonly regarded to have evolved from nitrate-respiring bacteria. Some researchers regard denitrification to be the precursor of aerobic respiration; others feel the opposite is true.
