Figure 1.
Discriminant plot for the first and second functions of the PLFAs identified in (a) the three raw animal manures (cow, horse and rabbit), and (b) the manures after being processed by the epigeic earthworm species Eisenia andrei, Eisenia fetida and Perionyx excavatus during the active phase of vermicomposting.
Figure 2.
Changes in (a) Gram-positive bacterial PLFAs, (b) Gram-negative bacterial PLFAs, (c) actinobacterial PLFAs, and (d) fungal PLFA 18:2ω6c of the three different animal manures (cow, horse and rabbit) after being processed by the epigeic earthworm species Eisenia andrei, Eisenia fetida and Perionyx excavatus during the active phase of vermicomposting.
Values are means ± SE. Controls are the manures incubated without earthworms.
Figure 3.
Changes in (a) bacterial growth rate, estimated as leucine uptake, (b) microbial activity, measured as basal respiration, and (c) carbon loss (percentage of initial) of the three different animal manures (cow, horse and rabbit) after being processed by the epigeic earthworm species Eisenia andrei, Eisenia fetida and Perionyx excavatus during the active phase of vermicomposting.
Values are means ± SE. Controls are the manures incubated without earthworms.
