Bacillus velezensis is taxonomically classified within the phylum Firmicutes, family Bacillaceae, and genus Bacillus, sharing its genus with Bacillus subtilis and Bacillus licheniformis. In the past, it was initially regarded as a subspecies of Bacillus subtilis; however, subsequent 16S rRNA sequencing confirmed its status as an independent species, a classification that has since gained widespread acceptance in the scientific community.

Q: What is the origin of the name Bacillus velezensis?

The name Bacillus velezensis derives from its original isolation site, the Vélez region of Spain; accordingly, the Chinese translation is “Bacillus velezensis,” a designation that has been universally accepted by the domestic microbial taxonomy community and is widely used throughout the field.

Biological Characteristics of Bacillus velezensis

The biological characteristics of Bacillus velezensis determine its practical value. Its core traits can be broadly categorized into morphological and physiological features, as well as metabolic product profiles; these are widely regarded within the industry as the key advantages that set Bacillus velezensis apart from other Bacillus species.

Morphology and Stress-Resistance Physiological Traits

Bacillus velezensis is a Gram-positive bacillus, with individual cells measuring approximately 0.5–1.5 μm in size. It produces highly resilient endospores; the ellipsoidal spores are located centrally within the cell and exhibit exceptional tolerance to adverse conditions such as high temperature, drought, and extreme pH. This makes it well suited for formulation into dry powder preparations that can be stored long-term, with a viability loss of less than 10% after more than 12 months at room temperature—this characteristic constitutes a key advantage that enables the large-scale industrial production of Bacillus velezensis.

Characteristics of Core Metabolic Products

Bacillus velezensis can secrete a variety of antimicrobial bioactive compounds, including lipopeptides, polyketides, and peptides, which exhibit inhibitory effects against numerous plant pathogenic fungi and bacteria. In addition, this bacterium produces multiple degradative enzymes, such as amylase, protease, and cellulase, which help break down organic matter and enhance nutrient uptake by crops, thereby exerting dual functions of disease control and growth promotion.

Core application areas of Bacillus velezensis

At present, the applications of Bacillus velezensis are primarily concentrated in the field of green agricultural production; meanwhile, its use is gradually expanding into areas such as food processing, biomedicine, and environmental remediation. The application requirements vary across these sectors. In agricultural production, the standard operating procedure for using Bacillus velezensis is as follows:

1. The Bacillus velezensis original powder is mixed with a filler according to the desired application ratio to prepare a wettable powder or a granular formulation.
2. Three application methods are available: seed dressing prior to sowing, root irrigation after transplanting, or foliar spray during the growing period.
3. Based on the crop’s growth stage and the incidence of diseases, apply the product again every 10–15 days to ensure effective disease control.

Applications in the field of agricultural biological control

The agricultural sector is currently the broadest application area for Bacillus velezensis, primarily as a functional strain in biopesticides and bio‑organic fertilizers. It effectively controls soilborne diseases such as wilt, root rot, and bacterial wilt, while also promoting root growth and enhancing crop stress tolerance. Compared with chemical pesticides, Bacillus velezensis leaves no residue and does not pollute the environment, aligning with the principles of sustainable, green agriculture. By 2026, the number of domestically registered agrochemical products containing Bacillus velezensis had exceeded 200.

Expansion of applications in other fields

Beyond the agricultural sector, Bacillus velezensis can be employed in environmental remediation to degrade organic pollutants in water and to remediate soil contaminated with heavy metals. In the biopharmaceutical field, its metabolic products have also been shown to exhibit antibacterial activity and are currently undergoing preclinical research. In feed processing, Bacillus velezensis can serve as a probiotic additive, enhancing intestinal health in animals and improving feed utilization efficiency.

Comparison between Bacillus velezensis and Common Bacillus Species

Many practitioners often confuse Bacillus velezensis with the more commonly encountered Bacillus subtilis and Bacillus licheniformis. We have compiled a comparative analysis of the key publicly available industry parameters for 2026 as follows:

What are the differences in core functionality?

Compared with Bacillus subtilis, Bacillus velezensis exhibits stronger antibacterial activity and a broader spectrum of inhibition, delivering superior control over soil-borne diseases that are often difficult to manage with conventional chemical pesticides. Moreover, in contrast to Bacillus licheniformis, Bacillus velezensis demonstrates a more pronounced growth-promoting effect, making it particularly well suited for sustainable, organic agricultural production—this is the key reason behind the steady increase in its market share.

How to choose the right Bacillus strain?

If the primary goal is disease prevention and control, Bacillus velezensis should be prioritized; for low-cost, large‑scale organic fertilizer formulations, Bacillus subtilis is a suitable choice; and for feed additives or animal probiotics, Bacillus licheniformis is the more common option. Shaoxing Jiayun Biotechnology (www.jawinbio.com) offers Bacillus velezensis raw powder in various purities to meet the production needs of different applications.

The Correct Method for Storing Bacillus velezensis

The viability of Bacillus velezensis is highly sensitive to storage conditions; adopting proper preservation methods can prevent loss of activity and ensure optimal performance. Different formulations of Bacillus velezensis have distinct storage requirements.

Storage conditions for the original strain

Bacillus velezensis dry powder exhibits good stability. It is generally recommended to store it in a cool, dry, and well-ventilated indoor environment, with the storage temperature maintained between 0 and 25°C. Avoid direct sunlight and humid conditions. Under sealed storage conditions, the shelf life of Bacillus velezensis dry powder can reach up to 24 months. Once opened, it is advisable to use the product within 3 months to prevent a decline in activity.

Precautions for the Storage of Finished Products

Bacillus velezensis formulations should be stored separately from high-concentration chemical disinfectants, as such agents can kill the live spores and render the product ineffective. Additionally, liquid‑form Bacillus velezensis products must be kept at a low temperature of 5–15°C to prevent premature germination and inactivation caused by heat; the typical shelf life is 12 months.

Industry Development Trends of Bacillus velezensis in 2026

The Bacillus velezensis industry has been steadily upgrading alongside the development of green agriculture in China. By 2026, two core trends are expected to shape the sector, and the market potential remains substantial.
