Aspergillus oryzae CCT 3940, Aspergillus awamori NRRL 3112 and a Trichoderma sp.) were compared for their capacity to produce endo-polygalacturonase (endo-PG) in solid state fermentation. Maximum pectinolytic activity was reached in 72 h of growth, the best two fungal strains being A. niger T0005007-2 and A. oryzae CCT 3940. Three types of commercial purified pectin and four of unprocessed pect...
(UV) light-induced skin damage. On the other hand, overexposure to UV radiation can lead to a pathological increase in melanin production. Epidermal hyper-pigmentation results from the increased activity of melanogenic enzymes such as tyrosinase.
