Summary
Microbial preparations, including bacteria and fungi, can stimulate the release of lysozyme, a key immune protein. This finding helps explain the immune-stimulating properties of these microbial preparations.
Area of Science:
- Immunology
- Microbiology
Background:
- Lysozyme is a crucial component of innate immunity with diverse biological activities.
- It exhibits antibacterial, antiviral, anti-inflammatory, anticancer, and immunomodulatory functions.
Purpose of the Study:
- To investigate the effect of microbial preparations on lysozyme release and production.
- To assess lysozyme activity in human monocytic cell line THP-1 after in vitro exposure.
Main Methods:
- Human monocytic cell line THP-1 was exposed to different microbial preparations.
- Lysozyme activity levels in cell culture fluids were measured using a fluorescence-based assay.
Main Results:
- Exposure to bacterial and ascomycetes preparations stimulated lysozyme release.
- A significant increase in lysozyme activity was observed after one hour of exposure.
Conclusions:
- Selected microbial preparations can enhance lysozyme release.
- This mechanism may contribute to the known antibacterial and immune-stimulating properties of microbial preparations.

01:29Microbes in Food Production
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...
01:28Biological Methods for Microbial Control
Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...
01:25Production of Organic Acids
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...
01:22Lysosomal Hydrolases
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
01:18Surface Membrane Barriers
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...
