Probiotics

240
Probiotics are live, non-pathogenic microorganisms that confer health benefits by modulating the gut microbiota. The human gastrointestinal tract harbors a complex microbial ecosystem, and the balance of this microbiota is crucial for digestive and systemic health. Among the most extensively studied and utilized probiotics are species formerly classified within the genera Lactobacillus and Bifidobacterium. These organisms not only naturally colonize the human gut but are also consumed through...

Microbes in the Production of Fermented Foods

256
Lactic acid bacteria (LAB) and molds are instrumental in fermenting plant-based foods to enhance preservation and ensure year-round availability. These microbial processes convert plant carbohydrates into organic acids and other metabolites that inhibit spoilage organisms and contribute to the sensory qualities of the final product.In sauerkraut production, cabbage goes through a microbial succession that starts with cocci such as Leuconostoc mesenteroides. These microbes begin fermentation by...

Microbes in Food Production

320
Microbial fermentation is central to food biotechnology, enhancing flavor, texture, preservation, and stability. Fermentative microorganisms metabolize carbohydrates into organic acids, alcohols, and other metabolites that inhibit spoilage organisms and improve digestibility while contributing distinctive sensory qualities.In baking, amylases naturally present in flour hydrolyze starch into monosaccharides such as glucose, which Saccharomyces cerevisiae ferments anaerobically. Through...

Scale-Up Processes

90
The scale-up of microbial fermentation processes is essential in industrial biotechnology, allowing the transition from laboratory-scale experiments to commercial-scale production while aiming to maintain product yield and quality. This process requires meticulous adjustment of equipment design, process parameters, and contamination control strategies to accommodate increasing culture volumes.At the laboratory scale, cultures are typically maintained in 1 to 10-liter glass or autoclavable...

Microbes in Beverage Production

264
Alcoholic beverages such as wine, beer, and spirits are the products of microbial fermentation processes that transform simple sugars into ethanol and a wide array of complex flavor compounds. These transformations rely on the metabolic activities of specific yeasts and bacteria, which are selected and controlled to yield the desired beverage characteristics.Wine Fermentation and MaturationWine production begins with the crushing of grapes to release juice and pulp, forming a must that is...

Production of Organic Acids

89
Lactic acid, an important organic acid extensively applied in food, pharmaceutical, and biodegradable polymer industries, is primarily produced via microbial fermentation. This method is favored over chemical synthesis due to its environmental sustainability and capacity for enantiomerically pure product formation. Among various microbial processes, the fermentation of starch-based substrates stands out due to the abundance and renewability of raw materials like corn and potatoes.Hydrolysis of...

Summary

Developing probiotics requires rigorous identification, safety assessments via clinical trials, and scalable biomass production. Commercial viability is crucial for market entry of beneficial microbial strains.

Area of Science:

  • Microbiology
  • Biotechnology
  • Food Science

Background:

  • The global probiotics market has expanded significantly, yet few isolated strains progress to industrial development and market release.
  • Thousands of probiotic strains are isolated annually, but a complex development pathway limits commercialization.

Purpose of the Study:

  • To review the critical factors influencing the journey of a probiotic strain from laboratory isolation to market availability.
  • To outline the essential steps and considerations for successful probiotic product development.

Main Methods:

  • Strain identification using whole genome sequencing as the gold standard.
  • Safety and efficacy evaluation through in vitro, ex vivo, animal models, and human clinical trials.
  • Assessment of large-scale biomass production and preservation of live bacterial concentration.
