“…[11][12][13] By contrast, solid-state fermentation is a promising alternative since conidia and metabolites are generally produced in higher quantities when these microorganisms are produced on a solid substrate. [11][12][13][14][15][16] For example, Aspergillus oryzae has been reported to produce a 500-fold higher yield of recombinant chymosin in solid-state fermentation than in submerged fermentation. 17) In this context, efficient utilization of agro-industrial residues as carbon sources has been shown for the mass production of entomopathogenic fungi.…”

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.

“…Low water activity in SSF facilitates formation of spore on the solid substrate and the production of large quantities of enzymes, which is different from submerged fermentation (SMF) processes (Barrios-González, 2012). Microbial release of potassium from K-bearing minerals consists of fermentation and bioleach (Lian et al, 2008).…”

In this study, Bacillus circulans Xue-113168 biofertilizer was produced through solid state fermentation processes using food waste and feldspar. Results confirmed that solid state fermentation has considerable advantages compared to complex process (solid-state and bio-bleach). The control of pH, temperature, and humidity effectively led to the formation of 2×10 9 cfu/g spore and dissolution of potassium at a rate of 41.53%. Compound microbial fertilizer (CMF), formulated by humic acid and K 2 HPO 4 with biofertilizer, has a quick and durable effect. CMF increases the yield of rapeseeds by 75 to 89%, provides higher vitamin C and reduces nitrate in leaf. Yields of selenium-enriched jujube and jujube increased, respectively, in the CMF compared to the matrix control; rates of anthracnose and rust diseases also decreased. Furthermore, our results showed that CMF improved soil properties, such as organic matter, NPK content from 8.83 to 16.16 kg hm 2 , and reduced chemical fertilizer from 25 to 11%, respectively. For convenient medium, robust process and good effect, CMF is suitable for potassium deficiency and undeveloped arable land resources.

“…Generally, this process was carried out by using lignocellulosic wastes used as substrates and support material for microbial growth and production of several value added products. [4][5][6] The effective utilization of lignocellulosic components would play a significant role in economic enzyme production. For this reason, lignocellulosic substrate sometimes requires pretreatment to improve enzymatic hydrolysis by fungi.…”

Pleurotus eryngii was incubated on both peach and cherry agroindustrial wastes by solid state fermentation for 30 days without/with pretreatment conditions. The lignocellulosic substrates were pretreated with dilute acid and alkaline solutions, hot water before incubation. The maximum carboxymethyl cellulase and xylanase activities peaked on 3 rd and 5 th days under control conditions of both wastes, respectively. The highest laccase and manganese peroxidase activities reached to their maximum on 17 th day as 2193.06 ± 50.4 UL -1 and 732.73 ± 19.8 UL -1 , respectively. The highest aryl alcohol oxidase activity was obtained as 239.25 ± 7.3 UL -1 in control condition of peach cultures. The used pretreatment methods had generally negative effects on lignocellulolytic enzyme production. The highest lignocellulolytic activities were detected using peach wastes. To results, these wastes could be used as alternative, new and economic energy sources to produce high amounts of lignocellulolytic enzymes.
