The objective of this research was to study the effect of carbon and nitrogen sources on the production of chlamydospores of the fungus in a solid state fermentation system (SSF). Twelve substances were studied using a statistical strategy, evaluating their effect on the production of Chlamydospores Finally, using an optimization strategy, the modifications of the substances that favor the production of chlamydospores were defined, and the effect of these on the predatory capacity of the fungus was evaluated. Optimal conditions were the variability of 0.25% w / w ammonium sulfate and 0.56% w / w sodium acetate in broken rice. The maximum concentration reached under this condition was 2.27x107 chlamydospores g of dry substrate-1, with a productivity of 1.62x106 chlamydospores g of dry substrate-1 day-1. 2021 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49668215019 https://www.redalyc.org/journal/496/49668215019/ https://www.redalyc.org/journal/496/49668215019/html/ https://www.redalyc.org/journal/496/49668215019/49668215019.epub https://www.redalyc.org/journal/496/49668215019/movil 10.15446/dyna.v88n216.85978 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.216 Vol.88 |
