NOVELTY - Biocontrol composition comprises at least one isolated strain of bacteria comprising an isolated Bacillus megaterium strain (isolate A-07), an isolated Paenibacillus barcinonensis strain (isolate A-10), an isolated Pseudomonas fluorescens strain (isolate N-04), an isolated Bacillus cereus strain (isolate T-11), an isolated Lysinibacillus sphaericus strain (isolate T-19), an isolated Paenibacillus alvei strain (isolate T-22) and/or an isolated Paenibacillus alvei strain (isolate T-29).    USE - The biocontrol composition is useful: to protect plants against plant pathogens, where the plant pathogen is a fungus, a bacterium or a plant parasitic nematode, preferably Phytophora species including P. capsici or P. nicotianac, Rhizoctonia solani, Fusariurm species. including F. oxysporum, F. graminearum or F. pseudograminearum, Pythium ultimum, Verticillium dahliae, Alternaria alternata, Colletotrichum coccodes, Dickeya dadantii, Pectobacterium carotovorum carotovorum, Pectobacterium carotovorum brasiliensis, Streptomyces scabies or Meloidogyne incognita; to treat plants, plant cuttings, seeds or tubers and for growing plants from cuttings, seeds or tubers; to treat soil around the plants roots; for enhancing plant growth (all claimed); and as biofertilizer. The ability of the biocontrol composition comprised of (isolated Paenibacillus barcinonensis strain (isolate A-10)) to protect plants against plant pathogens was tested against P. capsici using dual culture assay for screening in vitro antibiosis activity. The results showed that isolated Paenibacillus barcinonensis strain (isolate A-10) exhibited 50.01% inhibition of P. capsici mycelial growth.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (a) the isolated Bacillus megateriurn strain having Microbial type culture collection (MTCC) accession number 42317; (b) the isolated Paenibacillus barcinonensis strain having MTCC accession number 42318; (c) an isolated Pseudomonas fluorescens strain having MTCC accession number 42319; (d) the isolated Lysinibacillus sphaericus strain having MTCC accession number 42320; (e) the isolated Bacillus cereus strain having MTCC accession number 42321; (f) the isolated Paenibacillus alvei strain having MTCC accession number 42322; and (g) the isolated Paenibacillus alvei strain having MTCC accession number 42323.
