KEMAMPUAN DEGRADASI DARI ISOLAT BAKTERI LIGNOLITIK ASAL CACING TANAH (Lumbricus rubellus) PADA SUBSTRAT GULMA TANAMAN PANGAN
Abstrak: A research aiming to
identify and evaluate lignin degradation capability of lignolytic bacteria
isolate isolated from earthworms on weeds crops substrates have been done in
Nutrition and Forage Laboratory of Animal Husbandary Faculty, Udayana
University for 3 (three) months. Evaluation on the degradation capability of
lignolytic substrate was based on clear zone diameter that was formed in the
substrates of water hyacinth, and water lettuce leaves. The research was based
on Completely Randomized Design (CRD) with 3 (three) treatments and 3 (three)
repetitions. The treatments are lignolytic bacteria isolates with codes EB1LG,
EB2LG and EB3LG. Research result showed that on the water hyacinth and water
lettuce leave substrates, showed that bacteria isolate coded EB1LG has highest
clear zone diameters (1,525 cm and 1,528 cm) were 1,05% and 0,64% or 0,15% and
1,32% higher than bacteria isolates coded EB2LG and EB3LG, yet statistically it
was not significantly different (P>0.05). Based on the research it can be concluded
that on all substrates, namely water hyacinth, and water lettuce leaves, the
three lignolytic bacteria isolated from earthworms have almost identical
capability in degrading lignin.
