The project focused on the use of beneficial disease-causing microorganisms (pathogens) as biological control agents for grasshoppers and locusts.

Composting is not a sterilization process and a properly composted product maintains an active population of beneficial microorganisms that compete against the pathogenic members.

It contains beneficial microorganisms and enzymes.

Natural miso is a living food containing many beneficial microorganisms such as Tetragenococcus halophilus which can be killed by over-cooking.

That means the compost should be teeming with beneficial microorganisms that do not pose a threat to human health.

The right pH, or acid-alkali balance, keeps nutrients and minerals available to plants and makes the environment amenable to beneficial microorganisms.

An hour from now, the rudbeckia will be composted, food for the beneficial microorganisms that will eventually turn it to humus to enrich my soil.

Symbiotic microorganisms, both beneficial and potentially pathogenic, reside in the gastrointestinal tract of humans.

Others: beneficial microorganisms that exist naturally in the environment may thrive in the mixture.

In some cases, a pasteurization step is not included to allow some beneficial microorganisms to remain in the growth substrate.
