3 results about "Lysobacter" patented technology

The genus Lysobacter belongs to the family Xanthomonadaceae within the Gammaproteobacteria and includes at least 46 named species, including: Lysobacter enzymogenes, L. antibioticus, L. gummosus, L. brunescens, L. defluvii, L. niabensis, L. niastensis, L. daejeonensis, L. yangpyeongensis, L. koreensis, L. concretionis, L. spongiicola, and L. capsici. Lysobacter spp. were originally grouped with myxobacteria because they shared the distinctive trait of gliding motility, but they uniquely display a number of traits that distinguish them from other taxonomically and ecologically related microbes including high genomic G+C content (typically ranging between 65 and 72%) and the lack of flagella. The feature of gliding motility alone has piqued the interest of many, since the role of gliding bacteria in soil ecology is poorly understood. In addition, while a number of different mechanisms have been proposed for gliding motility among a wide range of bacterial species, the genetic mechanism in Lysobacter remains unknown. Members of the Lysobacter group have gained broad interest for production of extracellular enzymes. The group is also regarded as a rich source for production of novel antibiotics, such as β-lactams containing substituted side chains, macrocyclic lactams and macrocyclic peptide or depsipeptide antibiotics like the katanosins.

A postharvest citrus biological preservative, preservation method and application

The application discloses a postharvest citrus biological preservative and a preservation method and application thereof. The preservative comprises, in terms of volume percentage, 40-100% of lysobacter enzymogenes LE16 autolysis fermentation liquor, 0-60% of propanil and 0.1-0.2% of Tween 80. The application further provides application and a method of the preservative in citrus biological preservation. The biological preservative is mainly the metabolic product of lysobacter enzymogenes LE16, has obvious biocontrol effect on green mold and green rot, reduces the rot rate of citrus fruits in the preservation process, and does not affect the fruit quality. The autolysis fermentation liquor is safe, non-toxic, environment-friendly, convenient to produce and can be applied on a large scale. In cooperation with chemical pesticides, the application can greatly reduce the pesticide application amount and pesticide residues under the condition of obtaining the same control effect, and has potential application value in postharvest citrus preservation.

Application of a siderophore derived from Lysobacterium

The present invention discloses an application of a siderophore derived from Lysobacterium. High-purity siderophore was obtained from the fermentation broth of Lysobacter OH11 through fermentation culture, XAD16 resin adsorption and desorption, and HPLC preparation. Mass spectrometry and nuclear magnetic resonance confirmed that the siderophore was a catechol type, composed of two catechol groups and one spermidine, with a molecular formula of C 21 O6N3H 27 The molecular weight is 417Da and it is named Sperbactin. The plate antagonism test showed that Sperbactin has strong antagonistic activity against rice bacterial leaf blight and rice bacterial leaf streak pathogen. 50 The concentrations of these substances are 15.44 mg / L and 16.76 mg / L respectively, which can be developed into highly effective bactericides.
