Enhanced catharanthine production in catharanthus roseus cell cultures by combined elicitor treatment in shake flasks and bioreactors.
It is suggested that malate and alginate combining treatment also stimulates defense responses, such as lipid peroxidation, in all C. roseus culture processes and this may mediate the indole alkaloid production via jasmonate pathway. Expand

Additions of KCl, mannitol, and a variety of synthetic precursors and bioregulators to the CCC cultures markedly improved indole alkaloid production and release of these alkaloids into the medium. Expand
A study on intersterility groups of Armillaria in China.
Mating tests were used to identify 282 basidiocarp specimens of Armillaria collected in 15 Chinese provinces, mostly in northern and southwestern parts of the country, and the sexual system of 13 taxa is tetrapolar heterothallism. Expand
Selection of fungal elicitors to increase indole alkaloid accumulation in catharanthus roseus suspension cell culture.
Different fungal mycelium homogenates stimulate different kinds of indole alkaloid accumulation, which ranged from 2- to 5-fold higher than the control, and some fungal culture filtrates efficiently elicited the biosynthesis of different indoles alkaloids. Expand
Improved β-thujaplicin production in Cupressus lusitanica suspension cultures by fungal elicitor and methyl jasmonate
A synergistic effect of fungal elicitor and ferrous ion on β-thujaplicin production was suggested by the study and improved volumetric productivity was 3- to 4-fold higher than obtained under standard conditions. Expand
Promotion of indole alkaloid production in Catharanthus roseus cell cultures by rare earth elements
Production of the indole alkaloids, ajmalicine or catharanthine, in cell suspension cultures of Catharanthus roseus was enhanced by cerium (CeO2 and CeCl3), yttrium (Y2O3) and neodymium (NdCl3, complex of chromium (III)-titanium (IV) and NaSeO4 treatments. Expand
Microwave irradiation is a useful tool for improving isolation of actinomycetes from soil
Microwave irradiation of soil was helpful for isolating Streptomyces spp. Expand
A study on intersterility groups of Armillaria in China
Mating tests were used to identify 282 basidiocarp specimens of Armillaria collected in 15 Chinese provinces, mostly in northern and southwestern parts of the country. Fourteen intersterile taxa were… Expand
Intergeneric hybridization between Pleurotus ostreatus and Schizophyllum commune by PEG-induced protoplast fusion
Intergeneric hybridization between Pleurotus ostreatus and Schizophyllum commune was studied using PEG-induced fusion and most fusants showed a significantly higher nuclear DNA content when compared to parental strains. Expand
Interspecific hybridization between Volvariella volvacea and V. bombycina by PEG-induced protoplast fusion
Results from arbitrarily-primed polymerase chain reaction (AP-PCR) fingerprints revealed that the majority of hybrids were similar to one parental type, but heterologous fragments were found in some hybrids, which indicated that rearrangement of mtDNA could have occurred after fusion. Expand
