Ancient Macedonian refers to an Ancient Macedonian.
Not only does this imply a very low probability of retaining an ancient chromosomal arrangement (and thus the ancient MAT-HI linkage) in the absence of sex-driven selective pressure, but the necessity of tolerating frequent aneuploidy within the population might drive selection against the accumulation of HI genes on any one chromosome.
These systems are the nearest analogue we have to the ancient microbial mats that were arguably the first organized ecosystem on the surface of the planet.
Four strains, Shewanella sp. OM1, Pseudomonas sp. OM2, Aeromonas sp. OM4, and Serratia sp. OM17, capable of anaerobic growth with As (V) reduction, were isolated from microbial mats from an ancient gold mine.
A funny thing happened on the way to my yoga mat: I learned that this ancient practice can really deliver on its promise to get your issues out of your tissues.
It promised Buddhist pilgrimage routes, picnics assembled in local supermarkets, hot-springs baths, contemporary art collections, traditional houses, ancient crafts and modern potters, hiking and tatami mats, ferry rides across the Inland Sea.
Extensive microbial mats grew over large areas of ancient shallow seafloors from at least 3.2 billion years ago until the present, and their fossil remnants promised to supplement the geobiological interpretations from the better-known stromatolites.
Microbial mats form sediments sampled from the ancient Zloty Stok gold mine (SW Poland) were used as the source of arsenic-metabolizing microbes, for several reasons.
Microbial mats samples were collected from an ancient gold mine located in Zloty Stok, Lower Silesia, SW Poland, and were used as the inoculum for isolation of dissimilatory arsenate reducers.
These hot spring mat communities are thought to be modern derivatives of ancient prokaryotic communities, and the long history of cyanobacterial and FAP cohabitation suggests the potential for horizontal gene transfer.
