Hi, Robert. What you're describing is a cage match between the strains of yeast. There are hundreds of them, and depending on how well established the strain in your start is, inoculating the starter a second time may have no discernable effect or it may change the starter. It depends entirely on which strain of yeast wins out. Susan
