“…After the submerged fermentation of I. fumosorosea, Rayati et al (2001) obtained 4.5 × 10 9 spores.g -1 biomass by stationary phase nutrient condition (surface system for sporulation) over 120 h. This result was 4-times higher than the conidia production achieved by the best solid media for ESALQ1296 and ESALQ1205. Another study using agro-industrial residues revealed that the proportion of 60% potato refuse and 40% sugarcane bagasse promoted high production of aerial conidia of B. bassiana (3.4 × 10 9 conidia.g -1 dry mass) in Erlenmeyer flasks (Santa et al, 2005), demonstrating the feasibility of these byproducts as alternative nutritional sources to produce entomopathogenic fungi. 3 Solid medium composition: WR = whole rice, BR = broken rice, MR = milled rice, BC = broken corn, WG = wheat grain, RH = rice husk, SM = soybean meal, SB = sugarcane bagasse.…”

“…17) In this context, efficient utilization of agro-industrial residues as carbon sources has been shown for the mass production of entomopathogenic fungi. [18][19][20][21] However, the absence of free water induces parameter variations (such as pH, temperature, moisture, dissolved oxygen or CO 2 ) that are difficult to control. A complementarity method between solid-and liquid-state fermentations has been attempted in sequential culture.…”

Many entomopathogenic fungi have been demonstrated to be potential agents for efficiently controlling mosquito populations. In the present study, we investigated a bioreactor system to produce metabolites and conidia by combining technological advantages of submerged and solid-state fermentations. The efficiency of fungal products was tested toward mosquitoes. Aspergillus clavatus (Eurotiales: Trichocomaceae) was grown by semi-solid-state fermentation in a bioreactor for up to 7 days. Depending on conidial doses (2.5×10 7 , 5×10 7 , 7.5×10 7 , 10×10 7 and 12.5×10 7 conidia/mL), mortality ranged from 37.2±15.0 to 86.3±5.0% toward larvae and from 35.8±2.0 to 85.2±1.5% toward adults. The metabolites (10, 20, 40, 60, 80 and 100% v/v) yielded mortality from 23.7±15.0 to 100.0±0.1% toward larvae, and two sprayed volumes (5 and 10 mL) reached 45.5±1.4 and 75.6±2.6% mortality, respectively, toward adults.

“…Several agro-industrial wastes (refused potatoes, coffee husks and sugarcane bagasse) have been used in SSF to produce spores from Beauveria bassiana to obtain biopesticides for biocontrol of pests of banana, sugarcane, soybean, and coffee (Santa et al, 2005). Colletotrichum truncatum is another fungus that has been studied under SSF and that possesses characteristics to be used as mycoherbicide against the difficult weed Sesbania exaltata (Pandey et al, 2000b).…”
