AB: Non-volatile taste components of Auricularia fuscosuccinea (brown and white strains), A. mesenteria [A. mesenterica], A. polytricha and Tremella fuciformis were determined. Ash contents ranged from 2.05 to 6.14% dry weight. Carbohydrate contents ranged from 68.88 to 88.14%. Both A. fuscosuccinea strains contained high amounts of crude fat (4.48 and 4.54%, respectively) and high amounts of crude fibre (11.69 and 8.51%, respectively). Crude protein contents were high in A. mesenteria and the white strain of A. fuscosuccinea (15.46 and 12.53%, respectively). All species contained very low amounts of soluble sugars but high amounts of other reducing sugars. Total free amino acid contents ranged from 0.53 to 1.24 mg/g. Contents of monosodium glutamate-like components ranged from 0.05 to 0.34 mg/g. Contents of sweet-tasting components ranged from 0.17 to 0.50 mg/g. Bitter component content was high in T. fuciformis. Total contents of 5'-nucleotides ranged from 0.69 to 5.39 mg/g. Flavour 5'-nucleotide contents were high in both strains of A. fuscosuccinea. The 5 types of fungi were considerably different in both their proximate compositions and taste components.

AB: In an orthogonal test for screening the liquid fermentation media for the culture of white fungus (Tremella fuciformis) spores (WFS), a suspension of the spores at a dose of 105 cells/ml was inoculated at 0.1 ml onto 9 media containing glucose, sucrose, peptone, wheat bran, (NH4)2SO4, MgSO4 and KH2PO4. The 9 media were formulated according to the orthogonal table L9 (34) with 4 factors, i. e., carbon sources (A) namely glucose and sucrose, nitrogen sources (B) namely peptone and (NH4)2SO4, wheat bran (C) and mineral elements (D) namely MgSO4 and KH2 PO4, at 3 levels. Variance analysis indicated that significant differences were noted in the growth increment of WFS among the 9 media (P < 0.01), and among 3 media for B (P < 0.01) or D (P < 0.05). The formula of the medium for the growth and multiplication of WFS was optimized as glucose 20 g, peptone 1 g, wheat bran 25 g, (NH4)2SO4 0.75 g, MgSO4 0.25 g, KH2PO4 0.5 g and distilled water 1000 ml.

AB: Biology and life table parameters of B. lambi were studied at different temperature while feeding on white mushroom (Agaricus bisporus) mycelium cultured on mushroom compost. The duration of egg and larval development, preoviposition and oviposition period, female longevity and the time to 50% mortality declined as temperature increased from 16 to 28C. The threshold temperature of development (female) was 9C and the thermal constant for completion of development (female) was 195 day-degrees. At 16, 20, 24 and 28C, the total fecundity (eggs per female) was 71, 67, 66 and 57, respectively, and the daily fecundity rate (eggs per female per day) was 5.6, 8.7, 8.7 and 9.1, respectively. The sex ratio (female per male) ranged from 1.9 to 2.1 at 16-28C. At 16, 20, 24 and 28C, the intrinsic rate of natural increase (rm) was 0.11, 0.18, 0.22 and 0.27, respectively, and the population doubling time was 6.1, 3.9, 3.2 and 2.5 days, respectively. All life stages of the mite died when exposed to 35C constant temperature for 24 h, or to 32C constant temperature for 12 days or to 31-35C (average 32.9C) ambient temperature for 4 days. B. lambi completed its development only when fed on A. bisporus mycelium growing on mushroom compost. It could not survive on mushroom mycelia of Auricularia auricula, A. polytricha, Ganoderma lucidum, Hericium erinaceus, Lentinus edodes, Pleurotus ostreatus, P. sajor-caju and Tremella fuciformis.

TP increased the cytoplasmic free calcium concentration of Fura-2-loaded murine splenocytes in a concentration-dependent manner and showed synergism with concanavalin A. No effect on the release of intracellular calcium was found without extracellular calcium. Verapamil (10 g/ml), a calcium channel blocker, was shown to inhibit the effect of TP on cytoplasmic free calcium, indicating that TP can affect the influx of extracellular calcium.

AB: Four acidic heteroglycans, T2a-T2d, were isolated from the fruiting body of T. fuciformis, cultivated in Fujian Province, China. They contained 1.9-2.9 % of acetyl groups and were composed of mannose (Man), glucuronic acid (GlcA), and small amounts of xylose, glucose and fucose. According to methylation analysis they had a mannan backbone consisting of 3-linked Man, and side chains containing glucosyl, mannosyl, fucosyl, xylosyl and GlcA residues. The side chains were attached through O-2, O-4 or O-6 in about 40% of backbone mannosyl residues. MWs of the 4 polysaccharides were 410, 250, 34 and 20 kDa, respectively. T2a-T2d induced human monocytes to produce interleukin-1 (IL-1), interleukin-6 (IL-6) and tumour necrosis factor (TNF) in vitro. The products of Smith degradation (T2a-S) and lithium degradation (T2a-L) of T2a and the product of deacetylation (T2b-D) of T2b also induced monocytes to secrete IL-1 as efficiently as the original polysaccharides, indicating that xylosyl and GlcA residues as well as acetyl groups were not important to promote the cytokine-stimulating activity.

Glycosidic linkage analysis showed that they had a mannan backbone consisting of 3-linked Man p, and side chains containing glucosyl, mannosyl, fucosyl, xylosyl, and glucuronic acid residues attached through O-2, O-4, or O-6 of about half of the backbone mannosyl residues. A partial acidic hydrolysate of T3a could be divided into a low-branching region (T3a-1, 2, 3, 4) mainly branched at the 2-position of 3-linked Man p in the mannan backbone, and a high-branching region (T3a-5A) branched at the 2,4- or 2,4,6-positions of 3-linked Man p in the backbone. The low-branching region, which is predominant in the backbone, was substituted with non-reducing terminal Glc pA, Fuc p and short side chains consisting of (1

The results showed that 6 of the 8 polysaccharide extracts (all except those from L. edodes and S. commune) had superoxide and hydroxyl radical scavenging activities. The protein content of the polysaccharide extracts appeared to contribute a direct effect on free radical scavenging activity, extracts with a low polysaccharide:protein ratio showing the strongest scavenging activities. However, none of the polysaccharide extracts had antioxidative activity as measured by detecting malondialdehyde (MDA) contents of mouse liver microsomes.

Male Sprague-Dawley rats were fed on 2 semisynthetic hypercholesterolaemic diets (1.5% cholesterol, 5% fat) each containing 5% dried powder of the 2 mushrooms. After 4 weeks of mushroom diet consumption, the serum total cholesterol concentration was significantly decreased in A. auricula and T. fuciformis diet groups (17 and 19%, respectively). A similar significant decrease in serum LDL cholesterol level was observed (24 and 31%, respectively). There was no significant difference found in serum HDL cholesterol concentration and the amount of liver total cholesterol and total lipids among the 2 mushroom diet groups and the control group. Only rats fed on the T. fuciformis diet had a significant decrease in serum triacylglycerols. Rats fed on the A. auricula diet had a significant increase in the levels of faecal neutral steroids and bile acids by 39 and 46%, respectively. T. fuciformis diet also increased significantly the faecal excretion of neutral steroids and bile acids in rats by 51 and 36%, respectively. In this study, both mushrooms had effective hypocholesterolaemic activity in rats.

AC raised the plasma insulin level in normal mice and significantly increased the activities of hepatic hexokinase and glucose-6-phosphate dehydrogenase, but decreased the activity of hepatic glucose-6-phosphatase. Furthermore, it reduced the glycogen content in the liver, increased the total lipid in epididymal adipose tissue, and lowered the plasma cholesterol level. Oral administration of a single dose of AC (50-300 mg/kg) did not affect the plasma glucose level in normal mice, but continuous oral administration of AC solution (0.75 g/litre), instead of water, for a prolonged period lowered plasma glucose level in mice injected once with streptozotocin (170 mg/kg, i.p.) on Day 0 of AC administration and in streptozotocin-induced diabetic mice.
