Abstract: This invention relates to biocontrol formulations suitable for reducing the susceptibility of plants to fungal phytopathogens and for degrading turf thatch. In one aspect of the invention, a culture of strain Streptomyces sp. WYE 53 ATCC 55750 is incorporated into suitable delivery medium and applied to plant seeds and roots. Another aspect of the invention is directed to a composition comprising cultures of strains Streptomyces sp. WYE 53 ATCC 55750 and/or Streptomyces sp. YCED 9 ATCC 55660 and to a method for degrading turf thatch by contacting the turf thach with cultures of strains Streptomyces sp. WYE 53 ATCC 55750 and/or Streptomyces sp. YCED 9 ATCC 55660 which are incorporated into suitable delivery medium.

Abstract: A human embryonic lung fibroblast diploid cell strain LBHEL(KCTC 0127BP) is highly susceptible to varicella zoster virus(VZV). A cell-free varicella zoster virus (VZV) is produced by (a) culturing the human embryonic lung fibroblast diploid cell strain LBHEL(KCTC 0127BP) of claim 1 in a culture vessel to give cultured LBHEL cells; (b) infecting the cultured LBHEL cells with VZV to give VZV-infected cells; (c) culturing and harvesting the VZV-infected cells; (d) disrupting the harvested cells to obtain a cell homogenate; and (e) centrifuging the cell homogenate to obtain a supernatant containing the cell-free VZV.
