| oligosaccharides produced by submerged cultures of claviceps africana and claviceps sorghi. | oligosaccharides produced by submerged cultures of c. africana and c. sorghi were isolated by semipreparative hplc. structure of 6-o-beta-d-fructofuranosyl-d-glucopyranose (blastose), 1,6-bis-o-(beta-d-fructofuranosyl)-alpha-d-glucopyranoside (neokestose) and two sugar alcohols, 1-o-beta-d-fructofuranosyl-d-mannitol (fructosylmannitol) and 1,6-bis-o-(beta-d-fructofuranosyl)-d-mannitol (bisfructosylmannitol) was determined by nmr spectrometry. maldi tof ms analysis revealed molecular ions [m+na]+ ... | 2005 | 16295657 |
| rediscovery of claviceps sorghi (ascomycotina: clavicipitaceae) in india. | during last twenty years, endemic claviceps sorghi was largely replaced in india by an introduced species claviceps africana. recently, c. sorghi was found and isolated from sorghum bicolor (gulbarga, karnataka). macroconidia were smaller than in the type description, 7.6-14.5 (avg. 11.4) x 3.8-6.1 (avg. 4.8) microm; microconidia were rounded to oval, 2.5-3 microm in diameter. when plated, only the macroconidia underwent secondary conidiation. sporulation was maintained only in cultures grown on ... | 2002 | 12000133 |
