| two new lanostanoids from ganoderma resinaceum. | two new lanostane triterpenoids, 3-epipachymic acid (3alpha-acetoxy-16alpha-hydroxy-24-methylene-5alpha-lanost-8-en-21-oic acid, 1) and 3alpha-(3-hydroxy-5-methoxy-3-methyl-1,5-dioxopentyloxy)-24-methylene-5alpha-lanost-8-en-21-oic acid (2), together with a known compound, 3-oxo-5alpha-lanosta-8,24-dien-21-oic acid (3), were isolated from the fruiting body of ganoderma resinaceum. the structure elucidation was accomplished by spectroscopic methods, especially nmr experiments. compound 2 showed s ... | 2007 | 17943562 |
| enhanced production of exopolysaccharides by fed-batch culture of ganoderma resinaceum dg-6556. | the objectives of this study were to optimize submerged culture conditions of a new fungal isolate, ganorderma resinaceum, and to enhance the production of bioactive mycelial biomass and exopolysaccharides (eps) by fed-batch culture. the maximum mycelial growth and eps production in batch culture were achieved in a medium containing 10 g/l glucose, 8 g/l soy peptone, and 5 mm mncl(2) at an initial ph 6.0 and temperature 31 degrees c. after optimization of culture medium and environmental conditi ... | 2006 | 16728961 |
| antimicrobial, cytotoxic and antioxidant activity of selected basidiomycetes from yemen. | dichloromethane, methanol and aqueous extracts of 23 selected basidiomycetes species fruiting bodies collected in yemen were screened in vitro for their antibacterial activities against three gram-positive bacteria (staphyloccocus aureus, bacillus subtilis, micrococcus flavus), two gram-negative bacteria (escherichia coli, pseudomonas aeruginosa) and against one yeast fungus (candida maltosa), as well as for their cytotoxic and antioxidant activity. the highest antibacterial activity was shown b ... | 2005 | 16259127 |
