Food microbiology is the study of the microorganisms that inhabit, create, or contaminate food.This includes the study of microorganisms causing food spoilage; pathogens that may cause disease (especially if food is improperly cooked or stored); microbes used to produce fermented foods such as cheese, yogurt, bread, beer, and wine; and microbes with other useful roles, such as producing ...

Microbial food cultures are live bacteria, yeasts or moulds used in food production. Microbial food cultures carry out the fermentation process in foodstuffs. Used by humans since the Neolithic period (around 10 000 years BC) [1] fermentation helps to preserve perishable foods and to improve their nutritional and organoleptic qualities (in this case, taste, sight, smell, touch).
Microbiology (from Ancient Greek μῑκρος (mīkros) 'small' βίος (bíos) 'life' and -λογία () 'study of') is the scientific study of microorganisms, those being of unicellular (single-celled), multicellular (consisting of complex cells), or acellular (lacking cells).
Some bacteria produce intracellular nutrient storage granules, such as glycogen, [70] polyphosphate, [71] sulfur [72] or polyhydroxyalkanoates. [73] Bacteria such as the photosynthetic cyanobacteria , produce internal gas vacuoles , which they use to regulate their buoyancy, allowing them to move up or down into water layers with different ...
Multiple studies have shown that there is a significant difference in the survival rate of Lactobacillus and Bifidobacterium under refrigerated (4°C) and room temperature (25°C) storage conditions. At room temperature (25±1°C), the number of probiotics decreased by 5 to 6 logarithmic units (down to 1/100,000) after 90 days of storage.
The definition of prebiotics and the food ingredients that can fall under this classification, has evolved since its first definition in 1995. [3] In its earliest definition, the term prebiotics was used to refer to non-digestible food ingredients that were beneficial to the host through their selective stimulation of specific bacteria within the colon.
Bioremediation can be carried out by bacteria that are naturally present. In biostimulation, the population of these helpful bacteria can be increased by adding nutrients. [6] [15] Bacteria can in principle be used to degrade hydrocarbons. [16] [17] Specific to marine oil spills, nitrogen and phosphorus have been key nutrients in biodegradation ...
