Importance of spore-forming bacteria in the food industry?

Answer 1

Spore-forming bacteria can survive conditions that eliminate vegetative cells. Many of these spore-formers are pathogens and/or cause spoilage. Both of these situations will result in economic losses.

Answer 2

The aim of the project is increasing our understanding of 1) key properties of lactic acid bacteria that are important for food production 2) mechanisms for survival and growth of undesirable bacteria in food and the food industryIn this project we analyse existing and new forms of antibacterial treatment.

Lactic acid bacteria (LAB) are useful bacteria for the food industry and are used as starter cultures in the production of, for example, cheese, yoghurt, sourdough bread and cured sausage, as a protective culture in products that are ready to eat and increasingly as probiotics, especially in dairy products. The ability that lactic acid bacteria have to inhibit the growth of other bacteria is important in this context.

Important issues for the food industryFor both health and financial reasons, microbial pollution must be minimised. At the same time it is important to be aware that the current methods for removing bacteria in food and food processing areas may have unfortunate effects.

There is a pressing need for knowledge and innovation in the areas "food for better health", "safe food" and "food quality". In this context, studies have been carried out into:

• Acid production
• Probiotics and prebiotics: lactic acid bacteria and health
• Lactic acid bacteria as cell factories/toolboxes for work with lactic acid bacteria
• Response to antimicrobial treatment and stress
• Salmonella and Staphylococci in biofilm
• Lactic acid bacteria's sensitivity to antibiotics

Nofima Mat has its own collection of strainsNofima Mat's collection consists of over 2,000 bacterial strains. It is steadily growing, both as a result of newly occurring strains and results of the strains already found in the base. The groups represented are especially lactic acid bacteria, Listeria, Staphylococci and Salmonella.

Answer 3

The bacteria they use in the food industry is found in quick breads and yeast. the negative way is effecting meats by making them spoiled

Answer 4

Bacteria have many industrial disadvantages as well

1:-They spoil the food and thus cause a great economical loss

2:-They may cause a lot of Diseases like fire blight of apple
