I’m not sure whether it was so much a matter of the Nazi government directly ordering DELAG’s dissolution as it was of that simply being a logical part of the process of shifting flight operations over to the government-controlled DZR. Perhaps that’s more a splitting of semantic hairs, though.

But yes, once the DZR took over flight operations in 1935 DELAG ceased to operate as a corporate entity.

ML Hope is right: All commercial operations of the Zeppelins from 1909 until 1935 was with the Deutsche Luftschiffahrts-Aktiengesellschaft DELAG. The Luftschiffbau Zeppelin (the Zeppelin Airship Construction Company, or LZ) built the Zeppelins but did not operate them.

A somewhat late answer.
The company you ask for was the Cargolifter AG. It got bankrupt after building a very small experimental airship and a very large construction shelter in the state Brandenburg (Germany) near Berlin. The shelter is now a tropical bathing paradise. A sucessor is constructing load lifting ballons up to 70 tons so far. If you like to know more search for Cargolifter.
