If not using antibiotics or other additives, it's just a matter of medium being cold enough. If it's too hot, the yeast (or whatever you are inoculating) might get killed or heat-shocked, which you maybe don't want. Since the incubator will bring the culture to 30C anyway, there's no point cooling it past that point. Yeast are probably fine at 37C, maybe ...

So if you want to use the media at 30°C, there is no need to wait longer. The media will only warm up again in the incubator until this temperature is reached. The addition of antibiotics is also uncritical, ...

When glucose and fructose are fermented separately, the uptake profiles indicate that both sugars are utilized at similar rates. However, when fermentations are conducted in media containing an equal concentration of glucose and fructose, glucose is utilized at approximately twice the rate of fructose. The preferential uptake of glucose also occurred when ...
