The invention belongs to the technical field of biological feed, and discloses a strain of separated lactobacillus nigrum, an insect protein fermented by the lactobacillus nigrum and application of the insect protein, the lactobacillus nigrum is Lactobacillus nigrum TC38, and the preservation number is CCTCC (China Center for Type Culture Collection) NO: M2022723. The strain has relatively strong acid production capacity, and also has relatively strong bacteriostatic activity on pathogenic bacteria or putrefying bacteria such as escherichia coli, staphylococcus aureus, listeria monocytogenes, vibrio parahaemolyticus, bacillus subtilis, pseudomonas putida and the like. When the strain is used for anaerobic fermentation of insect protein, the product is rich in organic acid, is convenient to store for a long time, and has a relatively good application prospect in aquaculture. 本发明属于生物饲料技术领域，公开了一株分离的黑氏乳杆菌及其发酵的昆虫蛋白及应用，所述乳杆菌为Lactobacillus hammesiiTC38，保藏编号为：CCTCC NO：M2022723。该菌株具有较强的产酸能力，同时对大肠杆菌、金黄色葡萄球菌、单核增生李斯特菌、副溶
