A comparative study of production of hydrophobin like proteins (HYD-LPs) in submerged liquid and solid state fermentation from white rot fungus Pleurotus ostreatus

Enhancing the nutritional profile and digestibility of lentil flour by solid state fermentation withPleurotus ostreatus

“…It presents numerous advantages versus the liquid-state modality, such as being rapider, less expensive, and approaching the most to the natural environment of several microorganisms 12 . It has been applied in by-products valorisation, and more recently, some attempts have been performed in beans 13 , lentils 14 or peas 15 . While bacteria and yeasts have been used to perform fermentation in solid state, less research relates to fungus, although some literature report positive findings with the common edible fungus Pleurotus ostreatus 16 .…”

Biosurfactants: The green generation of speciality chemicals and potential production using Solid-State fermentation (SSF) technology

“…The product yield of hydrophobins (in mg/g of biomass) produced by P. ostraeus for example, was two-fold higher when produced in SSF than in SmF. Indeed, these proteins were secreted during adhesion of mycelia to solid support as these molecules are responsible for surface hydrophobicity of mycelia during binding to the hydrophobic substrate (Kulkarni et al, 2020). Rhamnolipids production in SSF was also reported at threefold higher than in SmF by El-Housseiny et al, (2019).…”

Fungal biosurfactants, from nature to biotechnological product: bioprospection, production and potential applications

“…Moreover, a 107% increase in yield was achieved in solid culture with complex substrate (sesame oil cake) compared to submerged culture using YMG medium for production of hydrophobins from Pleurotus ostreatus . [ 218 ].…”

“…Most studies on cultivation in solid medium for biosurfactant production are conducted in complex residues (agro-industrial) [ 218 ], which can make extraction difficult due to the greater diversity of interaction (product-medium and medium-solvent), maintaining residual impurities in the recovered extract [ 55 ]. In addition, solid-state cultivation scale presents challenges to be overcome on an industrial scale, such as the design of bioreactors that allow automated control and monitoring of parameters of the cultivation process [ 219 , 220 ], as well as minimizing heterogeneity in terms of heat and mass transfers [ 55 ].…”
