What is it
Brevibacillus laterosporus is a spore-forming soil bacterium that has been investigated as a biocontrol agent and, in some products, marketed as a probiotic. Its proposed activity is producing antimicrobial compounds active against other microbes. There are essentially no controlled human trials, and its use as a human probiotic is not well established or validated for safety.

antimicrobial activity against other microbes
Mechanism onlyBrevibacillus laterosporus produces antimicrobial substances and has been studied as a biocontrol agent against insects, fungi, and some bacteria in laboratory and environmental settings. There are no robust human trials demonstrating a probiotic or therapeutic benefit, and its safety as an ingested human probiotic is not well characterized. Any human benefit is purely speculative based on microbial mechanisms.
Bottom line: B. laterosporus has antimicrobial activity in the lab, but there is no credible human evidence supporting its use as a probiotic.
Evidence is mixed
Evidence is confined to in-vitro and biocontrol studies; human efficacy and safety data are absent.
