Geobacillus thermoleovorans CCB_US3_UF5 is a thermophilic bacterium isolated from a hot spring in Malaysia. Here, we report the complete genome of G. thermoleovorans CCB_US3_UF5, which shows high similarity to the genome of Geobacillus kaustophilus HTA 426 in terms of synteny and orthologous genes.
The need to improve food security in Africa through culture of tilapias has led to transfer of different species from their natural ranges causing negative impacts on wild fish genetic resources. Loboi swamp in Kenya is fed by three hot springs: Lake Bogoria Hotel, Chelaba and Turtle Springs, hosting natural populations of Oreochromis niloticus. The present study aimed at better genetic charact...
Glycerol dialkyl glycerol tetraethers (GDGTs) are core membrane lipids of the Crenarchaeota. The structurally unusual GDGT crenarchaeol has been proposed as a taxonomically specific biomarker for the marine planktonic group I archaea. It is found ubiquitously in the marine water column and in sediments. In this work, samples of microbial community biomass were obtained from several alkaline and...
Dense microbial mats and/or streamers of various colors (white, yellow, pink, purple, orange, red, green, etc.) develop in neutral or alkaline hot springs as follows: The color is determined by interaction between microbes in hot springs and physicochemical factors such as temperature, pH, sulfur and light (Brock, 1978; Castenholz, 1988; Hanada et al., 1995; Hiraishi et al., 1999; Jørgensen and...
Various aspects of hot springs at Bakreshwar (Lat. 23°52'48″N; Long. 87°22'40″E) in West Bengal, India have been investigated since the middle of 20th century, but comprehending the complete diversity and the complexity of the microbial population therein has been in the continuing process. Some of these microorganisms are found to have immense industrial importance. Microbes generally exist in...
Physical and chemical barriers separate individual terrestrial hot springs and their affiliated communities of thermophilic bacteria. However, 16S rRNA gene sequence comparisons suggest that seemingly identical or closely related bacterial species are found in multiple hot springs that are separated by distances that range from a few meters to thousands of kilometers. To investigate whether thi...
Evolutionary analysis of microbes at the community level represents a new research avenue linking ecological patterns to evolutionary processes, but remains insufficiently studied. Here we report a relative evolutionary rates (rERs) analysis of microbial communities from six diverse natural environments based on 40 metagenomic samples. We show that the rERs of microbial communities are mainly s...
