Cordycepin, a nucleoside derivative, is an active component of parasitic fungus, Cordyceps militaris which has been known for many pharmacological activities. The present study was carried out to develop an extraction strategy for cordycepin and to evaluate its antimicrobial potential. Solventsolvent extraction method was used to extract cordycepin from liquid culture of C. militaris. Crude con...

This study reports on the optimization of the extraction conditions of cordycepin from Cordyceps militaris by using ultrasonication. For this purpose, the orthogonal experimental design was used to investigate the effects of factors on the ultrasonic-assisted extraction (UAE). Four factors: extraction time (min), ethanol concentration (%), extraction temperature (°C) and extraction frequency (k...

Cordyceps militaris is a fungus used for developing health food, but knowledge about its intraspecific differentiation is limited due to lack of efficient markers. Herein, we assembled the mitochondrial genomes of eight C. militaris strains and performed a comparative mitochondrial genomic analysis together with three previously reported mitochondrial genomes of the fungus. Sizes of the 11 mito...

In vitro fruiting bodies were produced from ten different isolates of Cordyceps militaris EFCC C-5736, EFCC C-5941, EFCC C-5976, EFCC C-6040, EFCC C-6849, EFCC C-7268, EFCC C-7342, EFCC C-7992, EFCC C-8027 and EFCC C-8549. Single ascospores were isolated from in vitro grown fruiting bodies and used for fruiting body production in brown rice medium by both intra-strain crossing and out-crossing....

The Cordyceps mushrooms have a long history as medicinal fungi. In Traditional Chinese Medicine, Cordyceps have been used to treat several conditions including cancers for thousand of years. Extracts from both mycelium and fruiting bodies of C. sinensis, C. militaris and other Cordyceps species showed significant anticancer activities by various mechanisms such as, modulating immune system and ...

Cordyceps militaris is a valuable medicinal mushroom that contains numerous bioactive ingredients such as cordycepin, adenosine, pentostatin, polysaccharides, and carotenoids. However, the contents of these substances in wild-type strains C. are relatively low. Recently, genome has been fully sequenced, genes involved biosynthesis beneficial constituents have identified. Therefore, research on ...

The influence of tidal and diel changes on the exchange of Petrolisthes armatus planktonic larvae was studied at the Catuama inlet, which represents an intermediate system of marine and estuarine environments in the Northeast Brazil. To characterize the larval abundance and vertical distribution, samplings were carried out in August 2001 at neap tide and 3 stations, with 3 hours interval over 2...

Cordyceps militaris 202 is a potential fungus for biotransformation zein, due to its various proteases, high tolerance and viability in nature. In this article, single factor experiment and response surface methodology were applied to optimize the liquid fermentation conditions and improve the ability of biotransformation zein. The optimized fermentation conditions were as follows: inoculum con...

A mutant library of Cordyceps militaris was constructed by improved Agrobacterium tumefaciens-mediated transformation and screened for degradation features. Six mutants with altered characters in in vitro and in vivo fruiting body production, and cordycepin formation were found to contain a single copy T-DNA. T-DNA flanking sequences of these mutants were identified by thermal asymmetric interl...
