The scientific evidence supporting the gut microbiome in relation to health maintenance and links with various disease states afflicting humans, from metabolic to mental health, has grown dramatically in the last few years. Strategies addressing the positive modulation of microbiome functionality associated with these disorders offer huge potential to the food and pharmaceutical industries to innovate and provide therapeutic solutions to many of the health issues affecting modern society. Such strategies may involve the use of probiotics and prebiotics as nutritional adjunct therapies.

What Are the Most Common Types of Probiotics?

A new study has shown that restoring environments to include a wider range of species can promote 'good' bacteria over 'bad' -- with potential benefits for human health. University of Adelaide researchers report, in the journal Environment International , that degraded, low biodiversity land and soils tend to harbour more 'opportunistic' bacteria, while healthy, biodiverse ecosystems favour more stable and specialist bacteria.

They found that the bacterial communities more commonly found in degraded landscapes had "potential pathogenic character," with many in the same genera as prominent disease-causing bacteria Bacillus, Clostridium, Enterobacter, Legionella and Pseudomonas. Restoring a more biodiverse ecosystem, however, changed the bacterial composition towards more potentially immune-boosting microbial diversity.

The researchers analysed soil bacterial communities from a restoration site with a progression of environments from cleared, degraded land to a restored, more biodiverse, natural reference ecosystem. They compared their findings with data from over samples from across Australia which had been assigned as disturbed or natural soils, and found consistent patterns in the proportions of opportunistic versus stable bacteria.

In healthy, biodiverse ecosystems this risk is reduced. The researchers say their study also points to a new way of measuring soil and ecosystem health using groups of bacteria as summary biological indicators.

Beneficial Microbes: The pharmacy in the gut

Scientists have observed bacteria using microscopes to identify them. But it is the living processes that bacteria use and the wastes they give off that can be used either for human benefit or that cause disease. Scientists believe it was the chemical processes of early cyanobacteria, harnessing the energy from the sun, that released the oxygen that makes up our atmosphere. It took approximately 2 billion years for the bacteria to build up enough oxygen in the atmosphere to allow for the evolution of multi-cellular organisms. Bacteria have long been used by humans to create food products such as cheese, yoghurt, pickles, soy sauce and vinegar. We are also able to use bacteria to break down our sewage and to clean up oil spills. Many bacteria are very fast growing — under ideal conditions, Escherichia coli E.

What are bacteria and what do they do?

Bacteria are microorganisms and they are useful to us. Bacteria are economically important as these microorganisms are used by humans for many purposes. The beneficial uses of bacteria include the production of traditional foods such as yogurt, cheese, and vinegar.

Bacteria are microscopic, single-celled organisms that exist in their millions, in every environment, both inside and outside other organisms. Some bacteria are harmful, but most serve a useful purpose. They support many forms of life, both plant and animal, and they are used in industrial and medicinal processes. Bacteria are thought to have been the first organisms to appear on earth, about 4 billion years ago. The oldest known fossils are of bacteria-like organisms.

Highlights existing strategies to preserve a balanced oral microbiome for practitioners and patients to follow. For millions of years, our resident microbes have coevolved and coexisted with us in a mostly harmonious symbiotic relationship. We are not distinct entities from our microbiome, but together we form a 'superorganism' or holobiont, with the microbiome playing a significant role in our physiology and health.
