What is the effect of the concentration of dissolved salts and sugars on the oxygen transfer rate?

• The saturation concentration of oxygen in the medium decreases with the concentration of dissolved salts and sugars, leading to a lower oxygen transfer rate
• The KLa of the medium decreases with the concentration of dissolved salts and sugars, leading to a lower oxygen transfer rate
• The KLa of the medium increases with the concentration of dissolved salts and sugars, leading to a lower oxygen transfer rate
• None of the above
