Is the lactobacillus acidophilus the variety that is dds-1?

No, Probiotic 50 Advanced Formula has a LA-14 lactobacillus acidophilus.

According to our manufacturer, when referring to DDS-1 or LA-14 it doesn't refer to the material; that phrase is only a trademark of a specific producer of the strain "lactobacillus acidophilus". There is no physical or scientific difference between the two strains.
