How is the fermentation process used in the industrial production of streptomycin?
Streptomycin is recovered by several methods. Generally employed method is the fermentation broth is acidified, filtered and neutralized. It is then passed through a column containing a cation exchange resin to adsorb the streptomycin from the broth.
Which medium is used in streptomycin fermentation is?
Streptococcus griseus is used in the large scale production of streptomycin, which utilizes carbon, nitrogen, mineral source etc….Streptomycin is commercially available as “Hypochloride” with a chemical formula C21H39N7O12. 3HCL.

How many phases are there in streptomycin production?
High rate of streptomycin production, however, occurs in the pH range of 7.6 to 8.0. The process of fermentation is highly aerobic and lasts approximately for 5 to 7 days and passes through 3 phases: (a) The First Phase: It takes about 24 hours to 48 hours.
What happens in batch fermentation?
Batch fermentation is a process where all the substrate and nutrients are added at zero time or soon after inoculation takes place, and the vessel is allowed under a controlled environment to proceed until maximum end product concentration is achieved.
Which organism is used for microbial production of streptomycin?
Streptomyces griseus Waksman
streptomycin-producing organism is Streptomyces griseus Waksman and Henrici.
How antibiotics are produced by fermentation?
Fermentation. Industrial microbiology can be used to produce antibiotics via the process of fermentation, where the source microorganism is grown in large containers (100,000–150,000 liters or more) containing a liquid growth medium. Oxygen concentration, temperature, pH and nutrient are closely controlled.
Which compounds are derived from fermentation process using Streptomyces?
Substances
- Amino Acids.
- Caseins.
- Culture Media.
- Quaternary Ammonium Compounds.
- Manganese.
- Sodium Chloride.
- Iron.
- Magnesium.
What is the mechanism of streptomycin?
Streptomycin irreversibly binds to the 16S rRNA and S12 protein within the bacterial 30S ribosomal subunit. As a result, this agent interferes with the assembly of initiation complex between mRNA and the bacterial ribosome, thereby inhibiting the initiation of protein synthesis.
What is batch and continuous fermentation process?
Batch and continuous fermentation are two industrially adopted fermentation processes to produce useful products from microorganisms. Batch fermentation is done in batch-wise. Continuous fermentation is done continuously while feeding nutrients and harvesting products at regular intervals.
How do Streptomyces produce antibiotics?
Another important process involving the production of antibiotics is the symbiosis between Streptomyces and plants, as the antibiotic protects the plant against pathogens, and plant exudates allows the development of Streptomyces.
Which of the following medicine is produced using fermentation?
Penicillin medicine is produced using fermentation.
How inoculum is prepared in the production of antibiotics?
The inoculum is prepared usually in form of a spore suspension, which is transferred into the fermentor by placing it in a metal vessel that is attached to the fermenter. The spore suspension may be blown into the fermentor by using sterile air or it may be allowed to run in under gravity.
What are the fermentation conditions for the ethanol production?
The optimum pH, temperature, and time were 5.5, 30°C, and 36 h, respectively. Maximum ethanol and glycerol yields were 0.48 and 0.06 g/g, respectively. The biomass yield was between 0.01 and 0.16 g/g of consumed glucose.
Why are fermenters used when producing penicillin?
Fermenters are containers used to grow bacteria and fungi in large amounts, eg Penicillium mould for producing penicillin (an antibiotic). Fermenters are usually made from a metal that will not corrode, such as stainless steel. Some have the capacity to hold thousands of litres.
What compounds are derived from fermentation process using Streptomyces Flavovirens?
Streptomycetes produce numerous antifungal compounds of medicinal importance, including nystatin (from S. noursei), amphotericin B (from S. nodosus), and natamycin (from S.
What is the source of streptomycin?
Streptomycin is the first discovered aminoglycoside antibiotic, originally isolated from the bacteria Streptomyces griseus. It is now primarily used as part of the multi-drug treatment of pulmonary tuberculosis.
Does streptomycin inhibit protein synthesis?
