The present invention relates to a Bacillus subtilis JCK-1398 strain (Accession No. KCTC 14084BP) having induced resistance activity in pine trees and various plants, a pesticidal or antibacterial composition comprising same as an active ingredient, a composition for controlling plant diseases or pests, and a control method using same. The Bacillus subtilis JCK-1398 strain of the present invention was experimentally confirmed to have control activity against pests, nematodes, and fungi, which cause various plant diseases, by inducing resistance in a host. Thus, the Bacillus subtilis JCK-1398 strain of the present invention can be effectively used to control related plant diseases and can be spread over a wide area through foliar spraying, and therefore is expected to be able to prevent the spread of pine wilt disease at low cost.

A method of controlling a biofilm comprises contacting the biofilm with probiotic species and contacting the biofilm with chemical disinfectant. The biofilm may be contacted with the probiotic species and the chemical disinfectant simultaneously or sequentially. The method provides a higher reduction in the amount of at least one microbial species in the biofilm, compared to a similar method applying only the chemical disinfectant. Furthermore, the method may provide an unexpected synergy between the probiotic species and the chemical disinfectant in controlling the biofilm.

A spore germination composition and method to produce a bioaugmentation solution that is added to an anaerobic digester or partially aerobic digester to increase biogas production. A nutrient-germinant composition comprises L-amino acids a phosphate buffer, an industrial preservative, and an optional source of potassium. The composition and spores of one or more Bacillus species are heated to a preferred elevated temperature range of 35° C. to 60° C. for an incubation period of around 20 to 60 minutes to form a bioaugmentation solution that is dispensed to the digester, preferably to the hydrolysis stage of the digester. A dose of bioaugmentation solution is added to the digester around once per day in an amount to provide at least 1000 CFU per mL of the full volume capacity of the digester, which can increase methane production by around 5 to 10% over operation of the digester without the bioaugmentation solution.
