The optimal SA concentration was100 lmoláL-1, where the highest ergosterol content of 2.33 mgág-1was obtained following 6-day cultivation with100 lmoláL-1SA supplementation, and which was significantly higher than the unsupplemented control（p ／ 0.01）. Following 4-day supplementation with50 lmoláL-1Me JA, the highest ergosterol content obtained was 1.988 mgág-1, which was 25.8 % higher than the unsupplemented control. Our data indicate that SA and Me JA supplementation improves ergosterol content in H.erinaceus mycelium.展开更多

Glucose and xylose were superior carbon sources for promoting mycelial growth resulting in mycelial concentrations of 3.99 g/L and 4.01 g/L, respectively;glucose was the best carbon source in terms of productivity (0.44 g/L/day). Experiments were also performed using yogurt whey as an alternative nitrogen source for submerged cultivation of H. erinaceum mycelia, and DCW and β-glucan content were compared with those with chemical nutrient medium. When whey was used as a nitrogen source, DCW and total amount of β-glucan were 2.3- and 2.8-fold higher, respectively, than that with chemical nutrient medium. Thus, whey appears to be an alternative nitrogen source for promoting H. erinaceum mycelial growth.展开更多

Extracts from the fungus Hericium erinaceus (HE) contain bioactive components that promote the proper functioning of the nervous system and potential effects on protection against neurodegenerative diseases, including dementia and motor dysfunctions. The objective was to evaluate the effects of the administration of the HE mushroom extract on visuospatial memory and morphology of neurons in the CA1 and CA3 regions of the hippocampus in ovariectomized rats. 40 young Wistar rats weighing 90 ± 10 g BW were used, which were distributed into four groups of 10 animals;Control Group, non-ovariectomized and untreated rats;Group E2, ovariectomized rats treated with estradiol (2 μg/kg/body weight);Group HE, ovariectomized rats treated with the extract of the fungus Hericium erinaceus (0.5 mg/kg body weight) and Group Ovx/ST, ovariectomized rats, without treatment. The animals were tested in the Barnes and Open Field maze, then they were sacrificed, and their brains were obtained to perform a histological analysis of neuronal morphology in the CA1 and CA3 areas of the hippocampus. The most outstanding results showed that the Ovx/ST group recorded the longest time to arrive at the escape box and stay in the Barnes maze. A correlation was observed between neuronal damage and function;in the groups that did not present satisfactory performance in the maze tests, morphological alterations were identified such as the presence of some neuronal somata with degeneration characteristics such as pyknosis, nuclear basophilia and shrinkage of the cells. Its soma, as well as a decrease in the nuclear area of CA1 and CA3 neurons. It is concluded that the fungus Hericium erinaceus exerted a neuroprotective effect on the neuronal bodies of the hippocampus, associated with better performance in the visuospatial recognition memory test.展开更多

文摘Hericium erinaceus polysaccharide(HEP)is widely regarded as a potential food additive because of its rich nutritional value.This study aimed to explore the effect of HEP on the eggshell quality of aged laying hens and to reveal the mechanisms with particular emphasis on the alterations of uterine microbiota and health.A total of 360 Jingbai laying hens at 58 weeks old were randomly allocated into 4 groups,with 6 replicates per treatment and 15 birds per replicate.The hens were fed basal diets supplemented with 0,250,500,or 750 mg/kg HEP for 8 weeks.The results showed that HEP supplementation enhanced eggshell quality by improving the eggshell ultrastructure,as evidenced by increased eggshell thickness and strength(P<0.05).HEP decreased the abundance of Enterobacterales,Yersiniaceae,and Rahnella and increased the abundance of Actinobacteria in the uterus(P<0.05).HEP inhibited the activation of the toll-like receptor 4(TLR4)/nuclear factor kappa B(NF-κB)signaling pathway and decreased(P<0.05)the mRNA expression of interleukin-1β(IL-1β)and tumor necrosis factor alpha(TNF-α).HEP promoted cell proliferation,as evidenced by the increased(P<0.05)expression of proliferating cell nuclear antigen(PCNA)and Proliferation Ki-67(Ki67),and reduced necrotic apoptosis by downregulating(P<0.05)the mRNA expression of cysteinyl aspartate specific proteinase 3(Caspase-3)and cysteinyl aspartate specific proteinase 9(Caspase-9).HEP restored the physiological function of the uterus and improved eggshell biomineralization as evidenced by the increased mRNA levels of ATPase plasma membrane Ca^(2+)transporting 1(ATP2B1),ATPase plasma membrane Ca^(2+)transporting 2(ATP2B2),and solute carrier family 26 member 9(SLC26A9)and decreased ovotransferrin(OVOT)expression(P<0.05).These findings suggest that dietary HEP supplementation can improve the functional integrity of the uterus and modulate uterine microbiota.The enhanced functional integrity of the uterus facilitates the regulation of the expression of proteins involved in eggshell biomineralization,thereby ultimately improving eggshell quality through the modulation of eggshell ultrastructure.
