How do you perform solid-state fermentation?
How do you perform solid-state fermentation?
Solid-state fermentation (SSF) is a common technique for the production of microbial metabolites [1]. The process of SSF is performed on a solid substrate with a low moisture content, with the advantages of a high product concentration but only a relatively low energy being required [2].
What does solid-state fermentation produce?
Solid State Fermentation (SSF) is a fermentation method used by several industries like the pharmaceuticals, food, textile etc., to produce metabolites of microorganisms using solid support in place of the liquid medium. It is defined as the growth of microbes without free-flowing aqueous phase.
What is solid submerged fermentation?
Submerged fermentation (SmF) is the process in which growth and decomposition (anaerobic and/or partially anaerobic) of substrates (i.e., carbohydrates) is accomplished by microorganisms in the presence of plenty of free water (liquid medium) (Mussatto and Teixeira, 2010).
Why solid-state fermentation is better than submerged fermentation?
There are a number of advantages of the use of solid state fermentation over submerged fermentation. It is a much more simple process which requires a lot less energy. It produces a much higher volumetric productivity and it is similar to the natural environment of certain fungi.
What is solid-state fermentation PDF?
Solid-state fermentation (ssf) is defined as the growth of microbes without free flowing aqueous phase. The ssf is alternative to submerged fermentation for production of value added products like antibiotics, single cell protein, PUFA’s, enzymes, organic acids, biopesticides, biofuel and aroma production.
What are the advantages of SSF?
SSF offers many advantages over conventional submerged fermentation (SMF) such as, simple and inexpensive substrates, elimination of the need for solubilisation of nutrient from within solid substrates, elimination of the need for rigorous control of many parameters during fermentation, product yields are mostly higher …
What are the advantages of the solid state fermentation over the submerged fermentation in production of industrial enzymes?
What are the advantages of the solid-state fermentation over the submerged fermentation in production of industrial enzymes?
How is solid-state fermentation different from submerged fermentation?
The key difference between solid state fermentation and submerged fermentation is that solid-state fermentation involves the cultivation of microorganisms on a solid substrate with a low moisture content while submerged fermentation involves the cultivation of microorganisms in a liquid medium which has more than 95% …
What is solid-state fermentation?
Solid-state fermentation is a method that uses solid medium to culture mycelial and harvest enzymes on the substrate surface in the absence of or containing a small amount of liquid. With the continuous development and in-depth study, fungal enzyme production by solid fermentation has attracted more and more scholars’ attention.
What is the moisture content of substratum in solid state fermentation?
The moisture content of the substratum in SSF is usually maintained below 15%. The solid state fermentation is most commonly carried out for the production of fermented food products such as bread, fermented fish, meat, yogurt, cheese and pickles. The microbial fermentation increases…
How to ensure successful fermentation process in SSF?
Ample air circulation between the substrates should be ensured for the successful fermentation process in SSF. In SSF, excessive heat will be generated in the substrate and it should be cooled by providing adequate air circulation. The cultures used in SSF may be pure cultures or mixed cultures depending upon the requirement.
How to increase the production of cellulase in fermentation?
When soluble substrates are used in the fermentation process, the degradation products may hinder the synthesis of cellulase. To increase the production of cellulase via fermentation technology, different gradients of cellulase can be added while maintaining optimized conditions [62].
