Instructions
Two heteropolysaccharides from Isaria cicadae Miquel differ in composition and potentially immunomodulatory activity.[Pubmed: 29802926]
Two novel heteropolysaccharides (JCH-1 and JCH-2) with molecular weights of 30.9 and 555.3 kDa were first extracted, isolated and purified from Isaria cicadae Miquel (I. Miquel). Monosaccharide analysis showed that JCH-1 and JCH-2 were composed of mannose, glucose and galactose with different monosaccharide ratio. In addition, JCH-1 had higher contents of sulfated and uronic acid compared to JCH-2. Based on MTT assay, JCH-1 and JCH-2 could markedly promote the proliferation of RAW264.7 cells and exhibit no cytotoxicity at a specific concentration range. The immunomodulatory assay exhibited that JCH-1 and JCH-2 could significantly enhance the viability of macrophage cells, and promote the release of NO, IL-6 and TNF-α. Furthermore, the immunomodulatory activity of JCH-1 was significantly better than that of JCH-2. These results proposed that I. Miquel had two polysaccharide fractions with different composition and JCH-1 is better to be developed as a functional food with the better immunomodulator activity.

A beauvericin hot spot in the genus Isaria.[Pubmed: 19766720]
Beauvericin is a naturally occurring cyclohexadepsipeptide originally described from Beauveria bassiana but also reported from several Fusarium species as well as members of the genus Isaria. Twenty-six isolates of Isaria species and its Cordyceps teleomorph, and ten taxonomically close strains including Beauveria, Nomuraea and Paecilomyces species were sequenced and tested for beauvericin production. Trees using ITS rDNA and beta-tubulin sequence data were constructed and used to infer the phylogenetic distribution of beauvericin production. A group comprising Isaria tenuipes and its known teleomorph Cordyceps takaomontana, Isaria cicadae and its Cordyceps teleomorph, Isaria japonica and Isaria fumosorosea, showed positive beauvericin production which correlated well with combined ITS rDNA and beta-tubulin phylogenies. The results suggested that beauvericin can serve as a chemotaxonomic marker for these limited species of the I. tenuipes complex.
