What are the advantages of solid state fermentation?
Although less employed at an industrial level, SSF is recognized to commonly offer a series of advantages over submerged (or liquid) fermentation (SmF), such as higher yields and productivities, extended stability of products, lower production cost, lower protein breakdown (which is especially important if an enzyme is …
What’s the basic condition of solid state fermentation?
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.
Why biomass determination is difficult in solid state fermentation?
During a solid state fermentation process, the microorganisms are intimately bound to a solid matrix, which poses difficulties for biomass measurements. Unlike submerged fermentation, fungal biomass cannot be quantitatively separated from the solid medium, and hence, direct measurements are impossible.
What are the significant disadvantages of solid state fermentation?
Disadvantages of Solid State Fermentation 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. Ø Bacterial contamination sometimes problematic.
What is the definition of solid state fermentation?
Solid-state fermentation (SSF) is defined as the fermentation involving solids in absence (or near absence) of free water; however, substrate must possess enough moisture to support growth and metabolism of micro-organism [1], [2], [3], [4].
Which is more important SSF or submerged fermentation?
SSF plays a more important role in industrial fermentation processes compared to the traditional submerged fermentation (SMF), because it resolves the problem of solid waste disposal.
Why was fermentation technology completely ignored after 1940?
A glance at the history of fermentation technology indicates that the SSF processes were nearly completely ignored in western countries after 1940 due to adaptation of submerged fermentation (SmF) technology. However, perhaps there was no logical reasoning for this at that time.
How is the first batch of fermented fertilizer formed?
The process generally involves placing of agroindustry waste into polyethylene bottle and then adding water into it. The bottle is kept at room temperature till soluble product is formed. The filtered soluble product is the fermented solution, which is also known as first batch of fertilizer.
