Laminated carbonaceous concentrations at the surfaces of sedimentary bedding planes could be explained as sedimented detrital carbon (of abiotic or biotic origin, including floating microbial colonies, cf. Thompson et al., 1990), films of purely abiotic carbon, or microbial biofilms.
The actors' countries of origin include Mexico, Chile, Puerto Rico, the Philippines and Argentina.
cEight isolates of unknown origin included.
On the other hand, the search in the NCBI peptide database resulted in 180 new TEM β-lactamase sequences as compared to the TEM mutation table, including 89 sequences from microbial origin and 91 synthetic constructs.
They have been classified into different groups based on their chemical composition and microbial origin and they are divided into five major classes which include glycolipids, lipopeptides, phospholipids, polymeric compounds and neutral lipids (Ron and Rosenberg 2001; Sen 2010).
However, if we consider a microbial origin of religious rituals, we should admit existence of microbial influence on non-religious rituals as well.
Many terpenes of plant origin are known to be active against a wide variety of microorganisms, including Gram-positive, Gram-negative bacteria and fungi [ 65], but to date there are only few reports on antimicrobial activity of terpenes from microbial origin [ 66, 67].
At about the time Pasteur was demonstrating the microbial origin of many infectious diseases, other men were discovering the chemical origin of certain cancers — skin cancers among workers in the new lignite industry in Saxony, and in the Scottish shale industry, and various cancers caused by exposure to tar and pitch.
Alliinase from microbial origin is another choice for this purpose.
EPS consists primarily of polysaccharides, proteins, glycoproteins, lipoproteins, and other macromolecules of microbial origin.
