The percentage of mice inoculated with type 2B or non type 2B material that showed clinical signs was low, probably because of the small amount of gray matter (PrPres) in the inoculum; attack rates were 100% among mice inoculated with gray matter from brain samples (data not shown).
The inoculum to substrate rate (ISR) was approximately 2 1.
The effect of airflow rate, inoculum amount and wheat straw loading on bioconversion was investigated using a statistical experimental design.
In this study, the role of six parameters: the type of immobilizing supports, loading rate, inoculum levels, C N ratio, trace nutrients concentrations and mixing rate, on methane production were investigated under thermophilic conditions (55 ± 1 °C) with synthetic substrate medium.
Production of L-asparaginase is greatly influenced by fermentation medium composition and culture conditions such as temperature, pH, inoculum size, agitation rate, and incubation time [ 17].
Bacterial growth curves can thus be fit by a sigmoid defined by inoculum, maximal growth rate (r) and growth plateau (K) (Murray 2001).
An increase in the pitching rate (inoculum dose) from 1.0 g, to 1.5 to 2.0 g/L in successive fermentation experiments, was reflected in a higher ethanol production and sugars consumption.
