Abstract
Rhamnolipid, a bioactive compound derived from Pseudomonas sp. Kmka-114, aimed to
assess the effects on growth, non-specific immunity and enzymatic profiles in juvenile
Catla catla through graded dietary supplementation. Juvenile catla were randomly
selected for thorough evaluations of blood, serum and liver tissues to determine
the influence on growth metrics, non-specific immune responses, enzymatic activity
and organ modulation. Throughout the feeding trial, there was a significant increase
in the activities of myeloperoxidase, lactose dehydrogenase and alkaline phosphatase
activity in 300 mg kg−1 biomass day−1 (6X).
Histopathological analysis of liver tissues at this concentration demonstrated no
hepatic cell damage, indicating the surfactant’s safety for the fish. Following
a withdrawal period, Catla catla displayed a stable assay result, highlighting the
necessity for further detailed studies to clarify the underlying mechanisms.
