The present invention relates to thermostable proteinases from thermophilic Bacillus species and their uses in the preparation of nucleic acid samples. The enzymes of the invention are stable and active at 65-80° C., but are readily autolysed or denatured above 90° C.

Compositions and methods are provided for benefiting plant growth. The compositions contain isolated bacterial or fungal strains having properties beneficial to plant growth and development that can provide beneficial growth effects when delivered in a liquid fertilizer in combination with a soil insecticide to plants, seeds, or the soil or other growth medium surrounding the plant or seed. The beneficial growth effects include one or a combination of improved seedling vigor, improved root development, improved plant health, increased plant mass, increased yield, improved appearance, improvedresistance to osmotic stress, improved resistance to abiotic stresses, or improved resistance to plant pathogens. The isolated bacterial strains include those of the Bacillus species including speciessuch as Bacillus pumilus, Bacillus licheniformis, and Bacillus subtilis.

The invention provides a microecological microbial agent for resisting banana vascular wilt and a preparation method thereof. A fermentation medium for the fermentation liquor of the microecological microbial agent for resisting the banana vascular wilt is prepared from the following components in percentage by weight: 0.1 to 10 percent of corn flour, starch, cane sugar or molasses, 1 to 10 percent of bean pulp, soybean meal, bran or beef extract and 1,000ml of water under the condition of the pH value of 6 to 9. The method comprises the following steps of: preparing bacillus subtilis seed liquor; inoculating the prepared bacillus subtilis seed liquor to the fermentation medium for culturing; and collecting the bacillus subtilis fermentation liquor after the fermentation is finished. In the microbial agent and the preparation method, the raw materials of the fermentation medium are economic and cheap; and the fermentation medium has a proper concentration, inoculation quantity and bottling quantity, so that the fermented product has higher activity for resisting the banana vascular wilt. The formula of the fermentation medium and the fermentation condition can make a fermentation product have high antibacterial activity and a low cost. The adopted detection method is fast and convenient and a straightforward detection result can be obtained by the detection method.

Genes have been identified in the Bacillus genome that are responsive to various metabolic conditions and growth cycle changes. The new responsiveness of these genes allows for their use in regulated gene expression in Bacillus sp. and for the monitoring of bioreactor health.

The invention relates to modified polynucleotides encoding modified proteases, and methods for altering the production of proteases in microorganisms. In particular, the modified polynucleotides comprise one or more mutations that encode modified proteases having modifications of the pre-pro region that enhance the production of the active enzyme. The present invention further relates to methods for altering the production of proteases in microorganisms, such as Bacillus species.
