Processes. This process consists of depositing a solid culture substrate, such as rice or wheat bran, on flatbeds after seeding it with microorganisms; the substrate is then left in a temperature-controlled room for several days.
What is advantage 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 …
How the pH can be maintained during solid state fermentation?
Maintain the moisture in a Humidity chamber, using the minimal media (pH adjusted). The pH of 1 M solution of citric acid is 3.24 and the pH range for fungal growth is 4-5.8. Usually, during fermentation of carbohydrate substrates especially, acidic products are released and the pH of medium drops.
What are the 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 raw materials are in xanthan gum?
Xanthan gum is produced by fermentation based on renewable carbohydrate raw materials, such as glucose syrup, sucrose, or starch. These are readily biodegradable and ecologically safe.
How is Xanthomonas xanthan gum produced?
Xanthan gum can be produce by aerobic fermentation process. The organisms used for its production includes Xanthomonas Campestris primarily, along with X. Campestris other strains of xanthomonas such as X. Carotate, X. Paraveriocola, X. Translucens, X. Vasoculoeum and X. Hederae can also be used.
What is the length of the xanthan chain?
Length of the xanthan chain varies depending upon 1. Bacterial strain used 2. Composition of media used 3. Down-stream processing. Average Molecular weight of Xanthan Gum is 2 into 10 6 Daltons. [3] It can be produced by fermentation of glucose, sucrose and lactose.
What is the medium required for aerobic fermentation?
The medium required for aerobic fermentation comprises of at least one carbon source from glucose, maltose and starch, water soluble nitrogen source such as peptone or yeast extract, magnesium salt, phosphate ions and other trace elements. [5]
