What is solid state fermentation process?
Solid state fermentation (SSF) is defined as the cultivation process in which microorganisms grow on solid materials without the presence of free liquid. From: Biotechnology of Microbial Enzymes, 2017.
What is solid state fermentation PDF?
Abstract. 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 is SSF and SmF?
Solid-state fermentation (SSF) and submerged fermentation (SmF) processes are used extensively for pectinolytic enzyme production using various microorganisms. Bacteria, yeasts, and fungi produce pectic enzymes both under SmF and SSF conditions.
What is solid state fermentation and 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% …
Which is better solid state fermentation and submerged fermentation?
l-Asparaginase can be produced either by solid-state fermentation (SSF) or by submerged fermentation (SmF). SSF is preferred over SmF as it is cost effective, eco-friendly and it delivers high yield of enzyme. SSF process utilizes agricultural and industrial wastes as solid substrate.
What is solid-state fermentation and submerged fermentation?
What are 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 are the advantages and disadvantages of solid state fermentation?
Introduction
| 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 is liquid state fermentation?
Submerged fermentation is a method of manufacturing biomolecules in which enzymes and other reactive compounds are submerged in a liquid such as alcohol, oil or a nutrient broth. Submerged Fermentation (SmF)/Liquid Fermentation (LF) SmF utilizes free-flowing liquid substrates, such as molasses and broths.
What is solid state cultivation?
Solid-state cultivation (SSC) involves the cultivation of microorganisms on moist solid particles surrounded by a continuous gas phase. Although SSC has been used for centuries in the production of traditional fermented foods, most biotechnological products are currently produced by submerged culture.
What are the substrate used in solid-state fermentation?
Solid State Fermentation (SSF) Substrate The most regularly used solid substrates are cereal grains (rice, wheat, barley, and corn), legume seeds, wheat bran, lignocellulose materials such as straws, sawdust or wood shavings, and a wide range of plant and animal materials.
