TL;DR: This chapter presents some examples of the traditional process for conidia production from different biological control agents, and some characteristics are described on the use of plastic bags as bioreactors.
Abstract: The demand for chemical-free food has driven the use of pesticides based on microbial agents for integrated pest management. Entomopathogenic fungi have been widely used and are considered important biological control agents. Fungal biomass and conidia production are carried out regularly by solid-state fermentation at different scales. This chapter presents some examples of the traditional process for conidia production from different biological control agents; first some characteristics are described on the use of plastic bags as bioreactors; then this chapter will focus on studies aimed at the production of fungal conidia in either static or agitated bioreactors, under solid-state fermentation, and their achievement at industrial level.

TL;DR: In this paper, el efecto of las condiciones de cultivo (FES and FEL) and the tipo de soporte inerte (espuma de poliuretano, agrolita and tezontle) in the produccion of xilanasa by Aspergillus fumigatus was evaluated.
Abstract: Los procesos de fermentacion pueden ser divididos generalmente en Fermentacion en Estado Solido (FES) y Fermentacion en Estado Liquido (FEL) presentando diferencias en el comportamiento de los microorganismos. Ambos sistemas han sido estudiados para la produccion de enzimas utilizando microorganismos de interes industrial como Aspergillus sp. que produce xilanasas con importantes aplicaciones industriales. En este trabajo se evaluo el efecto de las condiciones de cultivo (FES y FEL) y el tipo de soporte inerte (espuma de poliuretano, agrolita y tezontle) en la produccion de xilanasa por una cepa identificada como Aspergillus fumigatus. La actividad enzimatica producida con agrolita (54.08 U/gms) y poliuretano (17.42 U/gms) fue mayor a la producida en FEL (2.06 U/mL). El uso de tezontle impidio la produccion de xilanasas. Adicionalmente, la productividad en FES utilizando agrolita fue 18 veces mayor que la obtenida en FEL, asi mismo, con el uso de PUF la productividad aumento 9 veces en relacion con el cultivo liquido. De esta manera, la comparacion de los parametros cineticos permitio concluir que la FES utilizando agrolita como soporte inerte genera una mejor alternativa para la obtencion de enzimas xilanoliticas utilizando A. fumigatus .
