Abstract

The invention relates to a Ruegeria mobilis strain YJ3 and application thereof. The preservation number of the strain YJ3 is CGMCC No.12381. According to the strain, by generating antimicrobial proteins, density induction quenching enzymes and the like, aquaculture diseases are prevented and controlled, and multiple common pathogenic bacteria can be inhibited, More importantly, the strain YJ3 has a remarkable inhibition effect on the luminous intensity of luminous vibrio and is capable of reducing the infection of luminous vibrio to artemia. The strain YJ3 has no toxic or side effects on shrimp seeds of Penaeus vannamei Boone and the artemia and can be used as a feed additive or an aquaculture water body additive to be applied to the aquaculture.

Description

technical field

[0001] The invention belongs to the technical field of beneficial bacteria screening, and in particular relates to a strain of Rudgeria mobilis and its application. Background technique

[0002] Shrimp farming is one of the important marine aquaculture industries in my country, which has brought huge economic and social benefits to our country. However, with the intensive, large-scale and high-density production of prawn farming, disease problems have become increasingly prominent. Vibriosis is the most common and most harmful bacterial disease in shrimp farming, which has caused serious economic losses in many countries in the world. The pathogenic bacteria that can cause vibriosis in prawns mainly include Vibriovulnificus, V.alginolyticus, V.anguillarum, V.campbellii, Vibrio brilliant bacteria (V.splendidus), mermaid Vibrio (V.damsela), prawn killing Vibrio (V.penaeicida), parahaemolyticus (V.parahaemolyticus) and Harvey Vibrio (V.harveyi) and so on. The...
