What benefits of Bacillus coagulans have been cited in the scientific literature?
In crop science, B. coagulans is reported to improve growth characteristics and root yield of sugar beet when applied as a plant growth-promoting rhizobacterium (PGPR) under combined high soil salinity and saline irrigation stress. Sugar yield improvements are also cited when this PGPR was combined with silica nanoparticles — both findings tied to that specific experimental system, not general field claims.
Aquaculture research characterizes B. coagulans as a candidate probiotic: in vitro studies report antagonistic activity against fish pathogens via ethyl acetate extract, whole-cell, and heat-killed cell preparations; it produces extracellular digestive enzymes and grows in fish mucus; and it showed no pathological signs after intraperitoneal injection in Oreochromis niloticus. The indexed literature also cites lipase production from coconut oil cake substrate — with a 3.2-fold yield improvement through medium optimization — and enhanced growth under mercury stress when cerium oxide nanoparticles are present.

2Potential claims from the literature
Reported to improve growth characteristics and root yield of sugar beet plants exposed to combined stressors of high soil salinity and saline water irrigation when applied as a PGPR (alone or combined with silica nanoparticles)
Reported to improve sugar yield of sugar beet under combined stressors of high soil salinity and saline water irrigation when applied as a PGPR combined with silica nanoparticles
Reported to exhibit in vitro antagonistic (bactericidal) activity against fish pathogens via cellular preparations/components including ethyl acetate extract, whole-cell product, heat-killed whole-cell product, and filtered broth
Reported to produce extracellular enzymes necessary for digestion of food materials and to grow in fish mucus, supporting its characterization as a candidate probiotic for aquaculture
Reported to tolerate bile juice and to be safe (no pathological signs, symptoms, or mortalities) upon intraperitoneal injection in Oreochromis niloticus, supporting its probiotic safety profile
Reported to produce lipase using coconut oil cake as a substrate, with a 3.2-fold increase in lipase production achieved through medium optimization
Reported to exhibit significantly increased growth in the presence of mercury (25 ppm and 50 ppm) when cerium oxide nanoparticles are applied, suggesting tolerance to heavy metal stress
