Yogurt is made using Lactobacillus species, which thrive in an anaerobic environment and derive energy through lactic acid fermentation. These are NOT the right species for an aerobic treatment plant. If yogurt does work, I suspect it would be due to the other nutrients in there such as sugars and fats which your aerobic bacteria can consume for energy. Animal carcasses contain lots of bacteria specialising in breaking down fats and proteins, which are present in wastewater too, so as long as those bacteria are primarily aerobic species it is going to help.
