Manure application is not permitted on frozen land in Canada and therefore, manure management and storage are the primary issues facing the agri-food industry. Low-cost, effective and environmentally safe earthen manure storage (EMS) facilities will lower costs and help make the livestock industry more competitive and efficient. The goal of this study was to develop a biological sealing technology for earthen manure storages. The results showed that it is feasible to use a growing culture of…

A New Strain of Bacillus tequilensis CGMCC 17603 Isolated from Biological Soil Crusts: A Promising Sand-Fixation Agent for Desertification Control
In arid and semi-arid desert ecosystems, physical, chemical, and vegetative measures were used to prevent wind erosion. However, studies on the utilization of microbial resources for sand fixation
Medium optimization and in vitro antioxidant activity of exopolysaccharide produced by Bacillus subtilis
The present study involves medium formulation using an agro waste, cane molasses, as the carbon substrate that was used instead of sucrose, to produce exopolysaccharide from Bacillus subtilis.
Nutritional factors affecting levan production by Bacillus sp.V8 strain isolated from rhizosphere bean (Vicea faba) plant
This investigation was designed to study the production of levan by fermentation; a number of 37 bacterial isolates were obtained from rhizosphere of different plants in Egypt and tested for levan
High Levan Production by Bacillus licheniformis NS032 Using Ammonium Chloride as the Sole Nitrogen Source
Protective effect of microbial levan against copper toxicity to Daphnia magna is observed for the first time and, contrary to most levan-producing strains, using ammonium chloride as the sole N source is observed.
Scaling up of levan yield in Bacillus subtilis M and cytotoxicity study on levan and its derivatives.
Results suggested that B. subtilis M could play an important role in levan yield on a large scale in the future and cytotoxicity of CL and its derivatives were evaluated.
Microbial levan from Brachybacterium phenoliresistens: Characterization and enhancement of production
The sequence alignment in the gene bank indicated that this isolate has a high percentage of similarity to the retrieved consensus sequence of Brachybacterium phenoliresistens strain phenol-A, and the results demonstrated that the optimal sources for carbon and casein during levan production were sucrose andcasein, yielding 7.88 g/land 8.12 G/l of levan, respectively.
Biocontrol of Soil Fungi in Tomato with Microencapsulates Containing Bacillus subtilis
Microcapsules containing B. subtilis strains could be effective biocontrol agents against soil fungi plant pathogens and could have a potential biofertilizer effect, since they stimulated growth and yield of tomato plants compared to control.
Production, Characterization and Valuable Applications of Exopolysaccharides from Marine Bacillus subtilis SH1.
Exopolysaccharides extracted by marine Bacillus subtilis SH1 had compact film-like structure, which could make it a useful in the future applications as in preparing plasticized film, and exhibited antibacterial activity against Aeromonas hydrophila, Pseudomonas aeruginosa and Streptococcus faecalis.
Studies on the production and optimization of levan from bacillus sp
Levan is an extracellular polysaccharide composed of fructose (fructans) with wide applications in pharmaceutical and chemical industries. The objectives of this research are to develop production
Partial purification of a Bacillus licheniformis levansucrase producing levan with antitumor activity.
The present paper deals with the study of the antitumor and anti-cytotoxic effect of levan produced by B. licheniformis and relatively the significantly high activity was observed against the HepG(2).


Effects of oil reservoir conditions on the production of water‐insoluble Levan by Bacillus licheniformis
B. licheniformis produced a water‐insoluble levan which has potential application as a selective plugging agent in microbial enhanced oil recovery (MEOR) and may thus be selectively controlled in the reservoir by substrate manipulation.
The potential of Bacillus licheniformis strains for in situ enhanced oil recovery
Abstract The ability of microorganisms isolated from oil reservoirs to increase oil recovery by in situ growth and metabolism following the injection of laboratory grown microbial cells and nutrients
selective production and characterization of levan by Bacillus subtilis (Natto) Takahashi.
B. Takahashi strain is the most efficient levan-producing strain among all of the B. subtilis strains tested and it produced the highest yield of levan in the least time under the common cultivation condition.

Levans are natural polymers of the sugar fructose found in many plants and microbial products that have potential industrial applications as thickeners and encapsulating agents and could provide additional, valuable products from sugarcane juice.
Production of Levansucrase from Bacillus subtilis NRC 33a and Enzymic Synthesis of Levan and Fructo-Oligosaccharides
Identification of levan indicated that fructose was the building unit of leVan, and hence conversion of fructose to levan reached 84% using 1000 μg/ml enzyme protein.
