A microorganism wherein one or more genes selected from the group of genes participating in sporulation in the middle to late stages of sporulation have been deleted or inactivated; and a process for producing a target product (a protein) by use the microorganism. No spore is formed when this microorganism is employed, thereby enabling production of a target product (a protein) while decreasing energy loss, production of a by-product and specific production speed to decrease unnecessary consumption of a medium. Moreover, the production period can be prolonged, whereby the target product (the protein) can be produced efficiently.
