We investigated the potential production and desiccation tolerance of microsclerotia (MS) by Brazilian strains of Metarhizium anisopliae (Ma), M. acridum (Mc) and M. robertsii (Mr). These fungi were grown in a liquid medium containing 16 g carbon l-1 with a carbon:nitrogen ratio of 50:1. One hundred milliliters cultures were grown in 250 ml Erlenmeyer flasks in a rotary incubator shaker at 28 C and 200 rpm for 5 days. Five-day-old MS were harvested, mixed with diatomaceous earth (DE) and airdried for 2 days at 30 C. The air-dried MS?DE granular preparations were milled by mortar ? pestle and stored in centrifuged tubes at either 26 or -20 C. Desiccation tolerance and conidia production were assessed for dried MS granules by measuring hyphal germination after incubation for 2 days on water agar plates at 26 C and for conidia production following 7 days incubation. Yields of MS by all strains of Metarhizium were 6.1?7.3 9 106 l-1 after 3 days growth with maximum MS yields (0.7?1.1 9 107 l-1) after 5 days growth. No differences in biomass accumulation were observed after 3 days growth, whereas Ma- CG168 showed the highest biomass accumulation after 5 days growth. Dried MS?DE preparations of all fungal strains were equally tolerant to desiccation (C93 % germination) and the highest conidia production was obtained by MS granules of Mc-CG423 (4 9 109 conidia g-1). All MS granules showed similar stability after storage at either 26 or -20 C for 3.5 months. |
