The present invention relates to xyloglucanases belonging to family 44 of glycosyl hydrolases and having a relative xyloglucanase activity of at least 30% between pH 5 and pH 8 are derived from the genus Paenibacillus especially from a strain of Paenibacillus polymyxa or Paenibacillus sp. The xyloglucanases exhibit high performance in conventional detergent compositions.

The invention relates to a microbial mixed colony capable of enhancing flavor of brewed white liquor, which comprises live brevibacillus borstelesis, clostridium.sp, bacillus subtilis, paenibacillus, clostridium thermo succinogene and brevibacillus brevis and can be used for brewing white liquor with strong aromatic flavor. The mixed colony is used in the fermentation process in brewing of the white liquor of the strong aromatic flavor to help a saccharifying starter improve the flavor of raw liquor. The mixed colony is capable of degrading cellulose, and can improve the utilization rate of liquor brewing raw materials and increase yield of white liquor. Meanwhile, the mixed colony is proved to have the characteristics of producing beneficial metabolins such as protease, amylase, organic acids, lipase and vitamins, along with ethanol resistance and heat resistance, and therefore enjoys a great advantageous in the brewing environment; and the metabolins are benefit for enhancing the flavor of the white liquor and increasing the nutrients in the white liquor.

Novel strains Paenibacillus sp. BS-0048, Paenibacillus sp. BS-0074, Paenibacillus polymyxa BS-0105 and Paenibacillus sp. BS-0277 and Fusaricidin A, Fusaricidin B and novel compounds 3 and 4 produced thereby have an activity of inducing resistance to plant diseases. Thus, they can protect plants from infections with fungi, bacteria, viruses and so on and, as a result, effectively control plant diseases.

The invention provides Paenibacillus sp. strain 1-43 which has nitrogen fixing capability and conservation number of CGMCC (China General Microbiological Culture Collection Center) No. 4965. The strain contains a nitrogenase structure gene nifH, and has the nitrogenase activity of 904.49 nmol C2H4 / (mg protein h)<-1> measured by an acetylene reduction method. The nitrogen fixing Paenibacillus strain 1-43 has an obvious inhibition action on multiple plant pathogenic bacteria; and the nitrogen fixing microorganism agent or biological organic fertilizer prepared from the strain 1-43 has an obvious promotion action on the germination and growth of plant seeds, can be popularized and used in agricultural production, and can effectively reduce the use amount of urea.

The invention discloses a solid bacterial fertilizer for remedying petroleum polluted saline alkali soil. The solid bacterial fertilizer consists of a flora mixed liquid, a high-salt beef extract peptone crude oil culture medium and a solid medium, wherein the flora mixed liquid consists of mixed bacillus, paenibacillus, bacillus coagulans, bacillus licheniformis and enterobacter; the flora mixed liquid is inoculated in the high-salt beef extract peptone crude oil culture medium for culture and enrichment; the solid medium consists of high pressure sterilized wheat bran and saw dust. The solid bacterial fertilizer has the advantages of simple preparation and easiness in obtaining of materials; when petroleum polluted saline alkali soil is remedied by using the solid bacterial fertilizer, the treatment cost is low, the ventilation property and the nutrition condition of soil can be improved, the secondary pollution to environment is prevented, and the degradation efficiency of petroleum hydrocarbon in saline alkali soil can be remarkably improved; after 60 days of remediation period, the salt content of soil is 6.1g / kg, and the petroleum degradation rate under the high salt condition can be up to 46.0%.

The invention provides a complex flora for preventing and treating peanut root rot and an application thereof, and belongs to the technical field of soil-borne disease prevention and treatment. The complex flora comprises pantoea, pseudobacillus, enterobacter, paenibacillus, sporosarcina, bacillus and pseudomonas aeruginosa. The pantoea, the pseudobacillus, the enterobacter, the paenibacillus, thesporosarcina, the bacillus and the pseudomonas aeruginosa in the complex flora have a synergistic interaction effect on inhibition of pathogenic fungi; compared with a single strain, the complex flora has the advantages that the rhizosphere colonization capacity is obviously improved, and the rhizosphere micro-ecological environment can be effectively optimized. The complex flora is inoculated topeanut roots, so that the peanut roots can be effectively prevented from being infected by fusarium oxysporum, and the health of the peanut roots is protected.

The subject invention relates to the surprising discovery that toxin complex (TC) proteins, obtainable from Xenorhabdus, Photorhabdus, and Paenibacillus, can be used interchangeably with each other. In particularly preferred embodiments of the subject invention, the toxicity of a “stand-alone” TC protein (from Photorhabdus, Xenorhabdus, or Paenibacillus, for example) is enhanced by one or more TC protein “potentiators” derived from a source organism of a different genus from which the toxin was derived. As one skilled in the art will recognize with the benefit of this disclosure, this has broad implications and expands the range of utility that individual types of TC proteins will now be recognized to have. Among the most important advantages is that one skilled in the art will now be able to use a single set of potentiators to enhance the activity of a stand-alone Xenorhabdus protein toxin as well as a stand-alone Photorhabdus protein toxin. (As one skilled in the art knows, Xenorhabdus toxin proteins tend to be more desirable for controlling lepidopterans while Photorhabdus toxin proteins tend to be more desirable for controlling coleopterans.) This reduces the number of genes, and transformation events, needed to be expressed by a transgenic plant to achieve effective control of a wider spectrum of target pests. Certain preferred combinations of heterologous TC proteins are also disclosed herein. Other objects, advantages, and features of the subject invention will be apparent to one skilled in the art having the benefit of the subject disclosure.

The present invention relates to novel isolated bacterial strains, which are members of the genus Paenibacillus, originally isolated from soil and showing antagonistic activity against a broad range of pathogens and being capable of producing antimicrobial metabolites. It was found that the strains Lu16774 and Lu17007 belong to a novel subspecies named Paenibacillus polymyxa ssp. plantarum while the strain Lu17015 belongs to a novel species which is proposed to be Paenibacillus epiphyticus. The present invention also relates to microbial pesticide compositions comprising at least one of such novel bacterial strains, whole culture broth or a cell-free extract or a fraction thereof or at least one metabolite thereof, and / or a mutant of at least one of said novel bacterial strains having all the identifying characteristics of the respective bacterial strain or whole culture broth, cell-free extract, fraction and / or metabolite of the mutant thereof showing antagonistic activity against plant pathogens. The present invention also relates to a method of controlling or suppressing plant pathogens or preventing plant pathogen infections by applying such composition. The present invention also relates to novel fusaricidin-type compounds which are metabolites produced by the strains of the present invention.
