Hormonal interactions in Mucor mucedo and Blakeslea trispora.
Evidence is presented that progametangia in both the plus and the minus mating types of Mucor mucedo can be induced by one substance, namely (-)-trisporic acid B. A method is described for the determination of the concentration of the sex factors (trisporone, trisporic acid B, trisporic acid C) in mated cultures of Mucorales by polarography. It can be demonstrated that the amount of plus myceli...
متن کاملHormonal control of tick development and reproduction.
Ecdysteroids (moulting hormones), juvenoids and neuropeptides in ticks are reviewed but, by far, the emphasis is on the former since this class of hormones has been the subject of most investigations. In immature stages of ticks, ecdysteroids have been shown to regulate moulting and to terminate larval diapause. Although there is a paucity of information on the molecular action of ecdysteroids ...
متن کاملProduction of extracellular aspartic protease in submerged fermentation with Mucor mucedo DSM 809
Fungal milk-clotting enzymes have gained value as bovine Chymosin substitutes in the cheese industry. In this work, the effects of culture conditions on the production of extracellular milk clotting enzymes from Mucor mucedo DSM 809 in submerged fermentation were studied. The maximum activity was observed after 48 h of cultivation at 24°C in Erlenmeyer flasks. The optimized initial pH and shaki...
متن کاملPurification and characterization of a glutathione S-transferase from Mucor mucedo.
An intracellular glutathione transferase was purified to homogenity from the fungus, Mucor mucedo, using DEAE-cellulose ion-exchange and glutathione affinity chromatography. Gel filtration chromatography and SDS-PAGE revealed that the purified GST is a homodimer with approximate native and subunit molecular mass of 53 kDa and 23.4 kDa, respectively. The enzyme has a pI value of 4.8, a pH optimu...
متن کاملHormonal Control of Reproduction in Fish for Induced Spawning
Reproduction in fishes is regulated by external environmental factors that trigger internal mechanisms into action. The final event of the reproductive cycle, the release of eggs and sperm resulting in spawning, can be controlled by either placing the fish in an appropriate environment or by changing the fish’s internal regulating factors with injected hormones or other substances. The internal...
