The impact of chemical additives on microbiological activity was studied by analysis of the samples every 30 days in order to detect the quantities of aerobic heterotrophs
Results for coliform and heterotroph
bacterial analysis in bottles and open containers were compared by using the Fisher exact test (Sigma Stat for Windows 2.
The next question is to figure out if particular heterotrophs
prefer to consume particular compounds.
Two major groups of microbes in the ocean play essential roles in transforming carbon compounds and moving them from the surface ocean to the deep ocean: autotrophs such as phytoplankton, which produce organic carbon compounds, and heterotrophs
such as bacteria, which recycle already-made organic carbon.
Therefore, if One could establish the isotope values of the photosynthetic production, chemosynthetic production, and heterotrophs
from the seeps, one could estimate the importance of chemosynthetic production.
, however, may have evolved from autotrophs, so the line 'autotrophs began to drool' could be taken as a poetic way of saying that autotrophs evolved into heterotrophs
, with the ability not only to use external food sources, but to drool at the prospect of eating them.
In studying our local deciduous forest, we learned more about forests plants in general, in the same manner that studying mushrooms or spotting a group of little white Indian pipes, we learned about heterotrophs
Water collected during mat compression, however, contained heterotrophs
(9,260 CFUs/100mL) as well as S.
Generally, nitrifiers are more sensitive to high temperatures than heterotrophs
, and significant nitrification cannot be expected after prolonged exposure to temperatures above 50[degrees]C (Walden and Wright 1995; Sierra and Marban 2000).
A culture of heterotrophs
was produced using culture broth and lake water.
Gulf Coast collection sites containing scaled heterotrophs
from Alabama, Mississippi, Louisiana and east Texas, 29 February-19 March 1996.
The data suggest, therefore, that the thermocline acts as a barrier to sedimentation, and allows microscopic heterotrophs
to consume detritus that has paused during its descent.
