Disclosed herein are the genetically modified Pseudomonas with improved tolerance to hydroxycinnamic acids.

Endophytic bacteria, compositions comprising the same, and methods of use thereof are disclosed which increase the root and shoot growth of cotton host plants, suppress growth of soil borne fungal pathogens of host plants, and increase resistance of the plant to salt stress and other abiotic stressors.

Microorganisms capable of effectively decompose hardly decomposable thermoplastic polyurethane, a method for decomposing thermoplastic polyurethane, and a method for selecting microorganisms capable of decomposing thermoplastic polyurethane are provided.

The method for selecting microorganisms capable of decomposing thermoplastic polyurethane includes a step of burying in soil a mixed sample of thermoplastic polyurethane having urea bond and polyurethane without urea bond and a step of collecting the microorganism adsorbing to the mixed sample after confirming the urethane decomposition by infrared spectroscopic analysis of the buried mixed sample.

The invention relates to a composition comprising: a) one or more polyhydroxyalkanoate (PHA) copolymers which contain, and preferably consist of, at least two different repeating polymer units chosen from the units (A) and (B) below, and also the optical or geometrical isomers thereof and the solvates thereof such as hydrates: -[-0-CH(R1)-CH2-C(0)-]- unit (A) -[-0-CH(R2)-CH2-C(0)-]- unit (B) in which polymer units (A) and (B): R.sup.1 represents a hydrocarbon-based chain chosen from: i) branched (C.sub.5-C.sub.9)alkyl, ii) (C.sub.10-C.sub.30)alkyl; iii) linear or branched (C.sub.5-C.sub.30)alkenyl; iv) linear or branched (C5-C30)alkynyl; v) (hetero)aryl; vi) (hetero)cycloalkyl; preferably the group i) (C.sub.10-C.sub.20)alkyl, or iii) (C.sub.8-C.sub.20)alkenyl; R.sup.2 represents a cyclic or non-cyclic, linear or branched, saturated or unsaturated hydrocarbon-based group, comprising from 1 to 30 carbon atoms; and b) a fatty medium comprising one or more fatty substances; preferably, the fatty substance(s) are liquid at 25°C and at atmospheric pressure; it being understood that (A) is different from (B).

Microbial compositions for application to plants, plant parts and plant seeds are provided for improvement of plant disease resistance and/or other beneficial plant traits, particularly resistance or tolerance to soybean sudden death syndrome (SDS) caused by a Fusarium species and/or disease caused by a Pythium species. Methods of making and applying microbial compositions or formulations to plants, plant parts or plant seeds or to growth media are further provided to increase or improve plant disease resistance and/or other beneficial plant traits.

A method of treating a biofilm on a surface, comprising: providing a surface having a biofilm; and administering to the surface a treatment that reduces a concentration of pyruvate of the biofilm, comprising pyruvate produced by at least a portion the biofilm, under conditions effective reducing maintenance of the biofilm on the surface. A composition, comprising purified enzyme, within a particle, effective for reducing pyruvate concentration in an aqueous suspension of the composition.

Provided are a novel polypeptide, a fusion polypeptide comprising the polypeptide, and a use thereof as an antibiotic. More specifically, provided are a novel polypeptide derived from a bacteriophage, a novel fusion polypeptide comprising cecropin A, and an antibiotic against Gram-negative bacteria comprising the polypeptide and/or the fusion polypeptide.

A Pseudomonas monteilii strain with salinity-alkalinity tolerance is provided. The strain is Pseudomonas monteilii 9-2, which has been deposited in China General Microbiological Culture Collection Center (CGMCC) on Oct. 25, 2021, with an accession number of CGMCC No. 23666; and an internal transcribed spacer (ITS) sequence is shown in SEQ ID NO: 1. This application further provides an application of the Pseudomonas monteilii strain in the degradation of petroleum hydrocarbons in a saline-alkali environment.

The present disclosure relates to a genetically modified microbial cell that includes a first genetic modification resulting in the expression of an exogenous vanillate demethylase, such that the microbial cell is capable of metabolizing an S-lignin decomposition product and producing 2-pyrone-4,6-dicarboxylate (PDC).

The present document discloses methods and means for treating and/or preventing ectoparasite infestations and/or gill parasite infection in teleosts by the administration of probiotic bacteria to the teleosts.
