What are the significant disadvantages of solid state fermentation?
Disadvantages of Solid State Fermentation Ø The growth rate of microbes on solid substratum is relatively slow. Ø Scale-up of the fermentation process is difficult. Ø Fermentation usually produces excessive heat in the medium. Ø The environmental conditions of the microbes cannot be regulated in SSF.
Which are the operational problems of solid state fermentation?
|No||Solid State Fermentation Disadvantage|
|1||Engineering problems due to the build-up of temperature, pH control, oxygen transfer, mass and heat transfer, substrate and moisture gradients|
|2||Uneven distribution of the cell mass, nutrients, temperature, pH, moisture content|
What are the advantages of the solid state fermentation over the submerged fermentation in production of industrial enzymes?
Advantages of Solid State Fermentation (SSF) No need for sterilization, less microbial contamination, and easy downstream processing. Utilization of agro-industrial residues as substrates in SSF processes provides an alternative avenue and value-addition to these otherwise under- or non-utilized residues.
Why is solid state fermentation better than submerged fermentation?
Solid-state fermentation uses a solid substrate to grow microorganisms while submerged fermentation uses a liquid medium to grow microorganisms. Thus, this is the key difference between solid state fermentation and submerged fermentation.
Which of the following is not true about solid-state fermentation?
Which of the following is not true of solid state fermentation (SSF)? Explanation: The chances of contamination is low because of less availability of water. However, the chances of contamination are more in submerged liquid fermentation.
Which of the following is not true about solid state fermentation?
What is solid state fermentation process?
Solid state fermentation (SSF) has been described as the process that takes place in a solid matrix (inert support or support/substrate) in the absence or near absence of free water (Singhania et al. 2010), but the substrate requires moisture to support the growth and metabolic activity of microorganisms (Thomas et al.
Which of the following is not true of solid-state fermentation?
What are the advantages of submerged fermentation?
3.1 Production of l-Asparaginase by SmF
|Submerged Fermentation||Solid-State Fermentation|
|Better heat and mass transfer can be achieved||Low water requirement, resistance to contamination|
|Better diffusion of microorganism||Substrate are agricultural wastes|
What is solid-state fermentation method?
What is solid state fermentation method?
How is solid state fermentation done?
Solid-state fermentation (SSF) is a fermentation mode carried out in the absence of free-flowing liquid (although containing sufficient water to allow microorganism growth), using a nonsoluble material that acts as both a solid support and a source of nutrients [1–3].
What is solid state fermentation example?
Examples include fermented bakery products such as bread or for the maturing of cheese. SSF is also widely used to prepare raw materials such as chocolate and coffee; typically cacao bean fermentation and coffee bean skin removal are SSF processes carried out under natural tropical conditions.
What are the disadvantages of submerged fermentation?
Expensive due to high cost of required media. Low volumetric productivity. More efflux is generated. Oxygen circulation is not so effective.
What is disadvantage of submerged fermentation SMF?
What are the disadvantages of solid state fermentation?
Disadvantages of Solid State Fermentation Ø Only those microbes that can survive in low moisture condition can be used in SSF. Ø Precise monitoring and accurate regulation of the fermentation process is not possible with SSF. Ø The growth rate of microbes on solid substratum is relatively slow.
What is SSF fermentation?
SSF is defined as fermentation involving solids in the absence (or near absence) of free water; however, the substrate must contain enough moisture to support the growth and metabolism of microorganisms.
Can solid state fermentation be used to produce lipids?
These microorganisms may be used for lipid production in solid state fermentation, resulting in an alternative process for lipid production that is both cost effective and large scale, and that uses A-IR as a unique carbon source and energy (Liu et al. 2013). In the literature, there are several reports of lipid production using SSF (Table 5).
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…
