Anaerobic biohydrogen fermentation was performed at various initial pH (5, 6, 7, 8 and 9) and various initial substrate concentrations (5, 10, 15 and 20 g/L) in 30mL serum bottles at mesophilic (37degC), anaerobic condition
Therefore, with the increasing of depth, an anaerobic condition
gradually formed in the deep litter system.
Rate constant of semiquinone anion radical formation under anaerobic condition
, and rate constant of autosensitized photooxidation reaction under aerobic condition were measured for Elsinochrome A (EA) by electron paramagnetic resonance and UV-visible spectra, respectively.
With the hydrolysis of sugarcane under anaerobic condition
Maximum amount of reducing sugar was produced on day 22 under anaerobic condition
Under anaerobic condition
, the gases formation occurred in three phases.
Bacteriological culture was done at 37[degrees]C both aerobically and under partial anaerobic condition
using Fortner's method (see Fig.
Of all of the samples analyzed, only the oldest, the Coonterunah carbonate samples from the early Archean of Australia, showed the presence of phosphite, Other natural sources of phosphite include lightning strikes, geothermal fluids and possibly microbial activity under extremely anaerobic condition
, but no other terrestrial sources of phosphite have been identified and none could have produced the quantities of phosphite needed to be dissolved in early Earth oceans that gave rise to life, the researchers concluded.
An anaerobic condition
is created and micro-organisms produce biogas which is composed of approximately 60% methane.

Fermentation under anaerobic condition
preserves the nutritive value and enhances the keeping quality of the fodder.
Due to its simplicity and reduced risks, the non-invasive methods to evaluate the physiological responses to exercise seems to be adequate for the determination of the aerobic and anaerobic condition
in humans and animals.
