Bacteria for Plants
Bacillus megaterium and B. subtilis are bacteria that are useful for plants. Bacteria for plants can be either beneficial for the plant or detrimental to the plant. In this post we’ll talk about beneficial bacteria for plants, specifically beneficial soil bacteria.
It is well known that beneficial plant bacteria play a critical role in supporting and increasing plant growth and plant health. Because of their ability to confer benefits to the plant, it is important that beneficial bacteria adequately colonize the plant’s environment, specifically the plant root system.
Sometimes called Plant Growth Promoting Bacteria, or PGPB, bacteria are a vital link in the food web for plants.
Here’s a brief introduction to two key beneficial plant bacteria, Bacillus subtilis and Bacillus megaterium.
Bacillus subtilis, or B. sub, is a key beneficial plant bacteria. B. subtilis plays a role in replenishing soil nutrients through both the carbon cycle and the nitrogen cycle. To aid the carbon cycle B. subtilis degrades thatch, pectin, cellulose and other organic materials. B. subtilis forms biofilms which are dense populations of organisms. These biofilms provides the plants with preventive colonization, sometimes called competitive inhibition. While beyond the scope of this post, preventative colonization essentially prohibits other microorganisms from forming colonies around the plant roots.
Another key beneficial plant bacteria is Bacillus megaterium. In addition to some of the benefits conferred by B. subtilis, B. megaterium is known to be a phosphate solubilizing bacteria (PSB). PSBs have several important benefits:
- They make phosphorus more available to the plant
- Reduce the need for traditional fertilizer applications
- Reduce Environmental problems downstream
- Promote sustainable agriculture.
Beneficial Plant Bacteria
The use of beneficial plant bacteria, like those above, has a very positive effect on plant growth, root mass, and crop yields. Specifically, beneficial plant bacteria produce plants with better growth response, biomass yield, and nutrient content when compared to plants without these important beneficial soil bacteria.
