AI Technical Summary

Technical Problem

In existing technologies, strains of the genus Tetracoccus lack the ability to tolerate salt and decompose starch, thus failing to effectively promote the growth and nutrient accumulation of black soldier fly larvae, thereby limiting the production efficiency and industrial development of black soldier fly farming.

Method used

A novel strain of Tessaracoccus sp. Tess.M30 was isolated and identified. It exhibits salt tolerance and starch-decomposing ability. After being inoculated into a culture medium and cultured, it was prepared as a microbial agent and applied to the breeding process of black soldier fly larvae to promote their growth and nutrient accumulation.

Benefits of technology

It significantly improved the growth rate and protein and fat accumulation of black soldier fly larvae, enhanced the biotransformation efficiency of black soldier fly larvae, and promoted the industrial production and economic benefits of black soldier fly larvae.

Abstract

A new strain of Tessaracoccus for promoting the growth of black soldier fly larvae and its application are provided, the strain comprises a 16S rDNA sequence shown in SEQ ID NO: 1 or its complement or a sequence having at least 85% nucleic acid identity compared with SEQ ID NO: 1. The Tessaracoccus sp. Tess.M30 disclosed in the application has the characteristics of decomposing starch and salt tolerance. Adding the functional bacteria in the process of black soldier fly breeding can promote the growth of larvae and promote the accumulation of protein and fat in larvae. Compared with adding sterile water, after adding Tess.M30, the body length and body weight of black soldier fly increase by 10.82% and 48.80% respectively, and the accumulation of protein and fat increases by 61.65% and 76.80% respectively. The application of the technology can improve the biological conversion efficiency of black soldier fly, and is conducive to promoting the industrialized production of black soldier fly larvae.
