, 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.
The study was performed on aerobic heterotrophs
contained in test-tubes under the sterile conditions; and the impact of chemical additives was analysed doublechecking all samples.
These organisms are then replaced by heterotrophs
that form a mucilaginous sheet over the original layer of bacteria-encrusted sand.
Furthermore, these results appeared to be generalizable beyond the scope of fecal indicator bacteria and included cultivable planktonic heterotrophs
Chemically defined media were needed for the cultivation of heterotrophs
by defining nutritional requirements.
5% incorrectly stated that spiders are autotrophs; half of them (45%) recognized that they are heterotrophs
Because of the pyrite auto-oxidation, fresh coal mine spoil is associated with high temperature, acid production and devoid of available organic nutrients, and expected to be inhabited by the extremophiles such as thermo-tolerant heterotrophs
(Norris et al.
Samples were analyzed for total coliforms, faecal coliforms, enterococci, and heterotrophs
by the membrane filtration method.
Water collected during mat compression, however, contained heterotrophs
(9,260 CFUs/100mL) as well as S.
are unable to synthesize fatty acids longer than 18-carbons, nor can they desaturate carbon-carbon bonds between the ninth and terminal methyl carbon, therefore, these essential fatty acids must be obtained from diet (Olsen 1999).

Microbes such as heterotrophs
, cyanobacteria, microalgae, and purple bacteria all produce biohydrogen in different ways.
