The invention relates to oceanic streptomyces parvulus and application thereof on the aspect of quorum sensing inhibition. The oceanic streptomyces parvulus is HY026 and has the preservation number of CGMCC No.8493. The streptomyces parvulus disclosed by the invention has high-efficiency low-toxicity quorum sensing inhibitory activity and obvious antineoplastic activity; one active component of the oceanic streptomyces parvulus can have an obvious quorum sensing inhibition effect under the concentration of 50mug per piece, has an obvious inhibiting effect on generation of an indicator Chromobacterium.Violaceum 12472 under the concentration of 12.5mug / mL; and the oceanic streptomyces parvulus has an inhibition ratio of 64.9 percent, which is superior to those of a large number of quorum sensing inhibition active materials or crude extracts reported currently. The strain has high yield of active ingredients. The oceanic streptomyces parvulus is expected to be applied to the development of a novel antimicrobial substance which uses a quorum sensing system as a target point.
