![]() Results from the anti-hydrogen peroxide and methyl viologen stress experiment showed that AAPsl could significantly prolong the life of worms under oxidative stress compared to the negative control group (P < 0.05). High AAP recovery rates and strong free radical scavenging rates of 2,2'-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) diammonium salt and 1,1-dibenzoyl-2-trinitrophenylhydrazine were obtained by 30% ethanol (AAPs1). ![]() Among these mushrooms, one unique mushroom is Auricularia auricular, having jelly like texture and is a renowned source of vitamins, proteins, minerals, fibers, trace elements, having the ability to low cholesterol level. AAP yield reached 13.91% ± 0.95% at a temperature of 7☌, liquid-to-material ratio of 75 mL/g, and extraction time of 70 min. About 14,000 species of mushrooms are known in the world in which 2,000 are safe for utilization of human consumption. Although they are found in Europe, Asia, North Africa and North America, they were the first cultivated mushroom in China around 100BC. auricula-judae powder, and time had the most obvious effects. Commonly called Jew’s Ear, Wood Ear, or Jelly Ear, Auricularia auricula-judae grows on both dead and living wood and can have a light or dark brown colour (getting darker as it ages). auricula-judae powder, enzyme usage, time, pH, etc.), temperature, ratio of liquid-to-A. The results showed that among the factors affecting AAP yield (temperature, liquid-to-A. Wood ear mushrooms (Auricularia auricula-judae) are large mushrooms that grow as crinkly clusters on old logs or decaying wood stumps in the wild. The names Auricularia auricula and Auricularia auricula-judae have been traditionally applied to the mushrooms described here, but fairly recent research (Looney and collaborators 2013, Wu and collaborators 2015) has determined that the auricula -like North American species of Auricularia are not properly placed under those species names. Optimal fractions with a high polysaccharide recovery rate and a strong free radical scavenging rate were obtained, and their antioxidant stress effect was studied using Caenorhabditis elegans as the model organism. Four ethanol concentrations (30%, 50%, 70%, and 90%) were used to grade AAPs. ![]() Response surface methodology with a Box-Behnken design was used to investigate the effects of a neutral protease on Auricularia auricula-judae polysaccharide (AAP) extraction yield. ![]()
