Alcaligenes faecalis (A. faecalis) is a member of the plant growth promoting rhizobacteria (PGPR). It has positive effects on promoting plant growth and development. Several studies have shown that A. faecalis has antifungal activity.
Therefore, through the search for its antagonistic strains, there may be new discoveries in antifungal aspects. CD BioSciences provides an advanced technology platform for A. faecalis -based PGPR screening service. Our MicroScanTM technology platform is development to meet customer's personalized customization needs.
Overview of A. faecalis
Basics about A. faecalis
- As an obligate aerobic gram-negative bacillus, A. faecalis is widespread in soils. It was originally named for its first discovery in feces.
- With an outer membrane, a thin peptidoglycan layer, and a periplasm, A. faecalis grow optimally in the temperature range of 20℃ to 37℃.
Colonization of Plant Roots by A. faecalis
- A. faecalis is present in the roots of plants. It is closely attached to the elongation zone and root hair one of the root systems, and less inside the meristematic zone of the root tip.
- By borrowing the intercellular space of the root epidermis and the base of the root hairs, A. faecalis may enter the root. They can reproduce in the intercellular spaces as well as within the root cells.
The Biological Activity of A. faecalis
Antibacterial Activity
A. faecalis was discovered to have antifungal activity against Aspergillus niger, Aspergillus flavus, Aspergillus mutans, Candida albicans, Alternaria alternata, Cercospora arachicola, Rhizoctonia solani, and Fusarium oxysporum.
Promoting Root Secretion
Inoculation with alkali-producing bacteria stimulated the secretion of rice roots under iron deficiency stress conditions and influenced the composition and content of root secretion. The increase of inter-root solution and intra-root ATP content could enhance the effectiveness of Fe and P elements in the inter-root soil and promote the uptake and utilization of phosphorus by plant roots.
Biodegradation of Organics
A. faecalis can decompose organic matter in wastewater, such as anionic surfactants. In addition, certain A. faecalis has good sulfide conversion ability. This bacterium is important to environmental protection.
Our Services
CD BioSciences provides probiotics screening service using A. faecalis as an indicator strain. Our MicroScanTM technology platform can discovery bacteria strains that promote the growth of the indicator strain, which together can be further developed as plant growth promoting rhizobacteria. This platform provides a new approach for screening and detecting microbial interactions and it can be applied to any microbial flora.
