The bacterial activity in rapid high heat methods breaks down the material to the extent that pathogens and seeds are destroyed, and the original feedstock is unrecognizable.
22.
In many situations bacterial activities, such as the production of the mentioned public goods, are only worthwhile as a joint activity by a sufficient number of collaborators.
23.
Meteoritic standard was chosen because of the constancy of the sulfur isotopic ratio in meteorites, whereas the sulfur isotopic composition in Earth materials varies due to the bacterial activity.
24.
U . S . and British research teams have submitted fossil evidence of bacterial activity embedded in meteorites recovered from the Antarctic and believed to be of Martian origin.
25.
Dead organisms in nature are usually quickly removed by scavengers, bacteria, anoxic environments ( where little bacterial activity occurs ) or when the organism had a particularly hard skeleton.
26.
Most geologists agree that crude becomes heavy as a result of biodegradation, in which lighter ends are preferentially consumed by bacterial activity in the reservoir, leaving heavier hydrocarbons behind.
27.
Hermetic grain storage strives to eliminate all exchange of gases within the storage system to mitigate bacterial activity as well as rodents and bugs from being able to breathe inside the storage systems.
28.
Glaxo has filed for approval of a combination of an antibiotic with a substance called ranitidine bismuth citrate ( RBC ), which is the active ingredient of Zantac modified to have some anti-bacterial activity.
29.
Some sulfate-reducing bacteria produce hydrogen sulfide, which can cause sulfide stress cracking . " Acidithiobacillus " bacteria produce sulfuric acid; " Acidothiobacillus thiooxidans " frequently damages RMS " Titanic " wreck are caused by bacterial activity.
30.
In addition to the direct blockage of light to the plant, benthic macroalgae have low carbon / nitrogen content, causing their decomposition to stimulate bacterial activity, leading to sediment resuspension, an increase in water turbidity, and the further attenuation of light.
