The invention belongs to the field of tools for in-situ colonization and culture systems for deep-sea microorganisms and in particular relates to a culture cabin for deep-sea microorganisms. According to the technical scheme, the uncovered culture cabin for deep-sea microorganisms comprises linear bearings (1), tension springs (2), a pressure compensation cavity (3), a fixed top plate (4), a deep-sea motor component (5), a fixed bottom plate (6), a hose (7) and a culture cabin body (8). The uncovered culture cabin has the beneficial effects that an end cover of the culture cabin body (8) is pushed away through rotation of the deep-sea motor component (5), microorganism enrichment culture is carried out in a completely open state and the end cover of the culture cabin body (8) is closed in laying and recovery processes to achieve sealing of the microorganism culture cabin body; the uncovered culture cabin can achieve microorganism enrichment culture in a deep-sea in-situ state; the safety during sample recovery can be ensured and the weight of the complete set of system can be effectively reduced by adopting the pressure compensation cavity (3).

The invention discloses pine wood nematode-killing Bacillus cereus, which is classified and named as Bacillus cereus NJSZ-13, and preserved in China type culture collection center, the preservation number is CCTCCM2016660, the preservation date is November 20, 2016, and the preservation address is Wuhan University in Wuhan in China. The Bacillus cereus NJSZ-13 isolated from bodies of pine trees has better competitive ability and colonization ability, and sterile fermentation broth and bacteria aqueous suspension of the Bacillus cereus NJSZ-13 both have strong nematicidal activity on pine wood nematodes. By experiments, 36h after the treatment, the killing rate of the sterile fermentation broth on the pine wood nematodes can reach 100%, bodies of the pine wood nematodes can be digested, 48h after the treatment, the killing rate of the bacteria aqueous suspension on the pine wood nematodes can reach 86.5%, and the pine wood nematode-killing Bacillus cereus has good practicability.
