    Abstract
    The surface mucus layer of corals aids in feeding, silt removal, and defense against pathogens. However, first line of defense of secreted mucus of corals against tissue damage generated through pathogen or environmental factors is poorly understood. Hence, we used various methods such as a well diffusion assay and tests for quorum quenching, free radical scavenging, antioxidant enzyme expression and phenoloxidase (PO) activity to determine the mucus defense properties using mucus of healthy and diseased Porites sp. and Acropora sp. Interestingly the coral mucus showed antimicrobial activity against coral pathogens such as bacteria and protozoan ciliates. Inhibition of the N-Acyl homoserine lactone (AHL) molecule suggests quorum quenching. Free radical scavenging of mucus was screened using hydrogen peroxide, hydroxyl radical, and 2, 2-diphenyl-1-picrylhydrazyl (DPPH) methods, which was found significantly more in diseased corals (p < 0.05). Antioxidant enzymes superoxide dismutase (SOD), catalase, and peroxidase activity were observed in both the diseased and healthy coral mucus. The presence of serine and metalloproteases was also detected in coral mucus. Further, phenoloxidase (PO) activity was highest in diseased coral mucus affected by pink line syndrome and white patch Acropora sp. disease than the healthy coral mucus. Thus, the present study of antimicrobial properties, antioxidant enzymes, and quorum quenching properties in coral mucus may aid in understanding the corals defense and survival against pathogens and any abiotic stress.
