cultures from 13 genera (Coprinus, Coriolus, Flammulina,
Lentinula, Lepista, Marasmius, Hypholoma, Pholiota,
Pleurotus, Schizophyllum, Stropharia, Suillus and
Volvariella) were tested on AOA. The CL and mycelium
suspension (MS) obtained on days 7 and 14 haven't
possessed AOA. The all samples showed different degree
of activity on 21 day. The CL samples were more active
than MSs. The highest AOA in CL of Pholiota alnicola
(44%) and in MS of Volvariella bombycina and Lepista
personata (26%) has been revealed. No correlation
between AOA and ecological belonging of tested species
has been observed. Further AOA-screening, study of
mechanism of action and dosa-effect correlations of active
compounds will assist in obtaining new biopreparations or
mushroom dietary supplements with antioxidant effect.

We investigated the impact of mycelium shiitake or
Agaricus bisporus, when associated with fibers, on body
weight. Material and methods Biscuits A were prepared
with 6% of mushroom powder (70% of Shiitake mycelia
grown on wheat and 30% of fibers) and Biscuits B 3% only
(70% of dried Agaricus bisporus and 30% of fibers). The
micture was finalised according to the patent
PCT/FR01/00577. Consumers were randomized. Each had
to eat 5 biscuits (50g) per day for 4 weeks. Body weight,
fat index, food intake, physical activity and global caloric
balance (caloric intake - physical activity) were compared.
Results 38 consumers were included: 19 (18 women) in
group A and 19 (14 women) in group B. 26 consumers
completed the form on food intake and physical activity.
Table 1: Populations A and B were comparable
Group A Group B
Mean age 30 ±10 35 ±10
Body weight (kg) 67 ±10 71 ±11
% of fat 30 ±6 32 ±10
For group A, caloric balance - for 4 weeks - was equal to
+998 kcal and +1562 for group B.
