Frequently Asked Questions (9)
Q2. What is the effect of bioaugmenting the anaerobic digestion process?
When the effect of bioaugmenting the anaerobic digestion process with a specific microorganism is positive, it can result in two effects: an enhancement in methane yield and/or an increase in the methane production rate.
Q3. What is the significance of the bioaugmentation strategy?
The presence of higher concentrations of stearate and palmitate throughout the experiment was a clear indication that the bioaugmentation strategy improved the hydrolysis.
Q4. What is the main drawback of bioaugmentation under anaerobic conditions?
The major drawback of using bioaugmentation under anaerobic conditions is the accumulation of LCFAs, which may inhibit the digestion process.
Q5. What is the effect of hydrolysis on the digestion of a poultry waste?
Salminen and co-workers11 reported that hydrolysis limited the digestion of a poultry slaughterhouse waste due to a high concentration of propionate, which was the consequence of the presence of LCFAs.
Q6. What is the effect of bioaugmentation on the digestion of wastes?
From a practical point of view, the effect of utilization of bioaugmentation as a strategy to improve the digestion of lipid-containing wastes is a decrease in the time required for digestion.
Q7. What was the problem with the approach adopted in this study?
The problem with the approach adopted in this study was that as hydrolysis occurred rapidly, the lipolytic activity could not be accurately related to the presence of an active lipolytic strain.
Q8. What was the abundant acid in the test sample?
Acetate (6–8 g dm−3) and propionate (2.5–4 g dm−3) were the most abundant acids for both treatment conditions investigated (Fig. 4).
Q9. What is the effect of bioaugmentation on the digestion of lipid-rich waste?
15,16In the present study, the effect of bioaugmentation by an anaerobic lipolytic strain as a means of improving hydrolysis and solubilization of lipids in the anaerobic digestion process of restaurant lipid-rich waste was studied using a model substrate.
