Isolated from Infected Pears () in Italy Produces Non-Host Toxins and Hydrolytic Enzymes as Infection Mechanisms and Exhibits Competitive Exclusion against in Co-Infected Host Fruits.

is one of the most devastating phytopathogenic fungi. This microorganism causes black spots in many fruits and vegetables worldwide, generating significant post-harvest losses. In this study, an strain, isolated from infected pears () harvested in Italy, was characterized by focusing on its pathogenicity mechanisms and competitive exclusion in the presence of another pathogen, .

Plant Growth-Promoting Bacterial Consortia as a Strategy to Alleviate Drought Stress in .

Drought stress is one of the most severe abiotic stresses affecting soil fertility and plant health, and due to climate change, it is destined to increase even further, becoming a serious threat to crop production. An efficient, eco-friendly alternative is the use of plant growth-promoting bacteria (PGPB), which can promote plant fitness through direct and indirect approaches, protecting plants from biotic and abiotic stresses. The present study aims to identify bacterial consortia to promote L.

Specialized Metabolites from the Allelopathic Plant as Potential Biopesticides.

To cope with the rising food demand, modern agriculture practices are based on the indiscriminate use of agrochemicals. Although this strategy leads to a temporary solution, it also severely damages the environment, representing a risk to human health. A sustainable alternative to agrochemicals is the use of plant metabolites and plant-based pesticides, known to have minimal environmental impact compared to synthetic pesticides.

CotG controls spore surface formation in response to the temperature of growth in Bacillus subtilis.

Bacterial spores of the Bacillus genus are ubiquitous in nature and are commonly isolated from a variety of diverse environments. Such wide distribution mainly reflects the spore resistance properties but some Bacillus species can grow/sporulate in at least some of the environments where they have been originally isolated. Growing and sporulating at different conditions is known to affect the structure and the resistance properties of the produced spore.

Genomic and Physiological Characterization of Bacilli Isolated From Salt-Pans With Plant Growth Promoting Features.

Massive application of chemical fertilizers and pesticides has been the main strategy used to cope with the rising crop demands in the last decades. The indiscriminate use of chemicals while providing a temporary solution to food demand has led to a decrease in crop productivity and an increase in the environmental impact of modern agriculture. A sustainable alternative to the use of agrochemicals is the use of microorganisms naturally capable of enhancing plant growth and protecting crops from pests known as Plant-Growth-Promoting Bacteria (PGPB).

The power of two: An artificial microbial consortium for the conversion of inulin into Polyhydroxyalkanoates.

One of the major issues for the microbial production of polyhydroxyalkanoates (PHA) is to secure renewable, non-food biomass feedstocks to feed the fermentation process. Inulin, a polydisperse fructan that accumulates as reserve polysaccharide in the roots of several low-requirement crops, has the potential to face this challenge. In this work, a "substrate facilitator" microbial consortium was designed to address PHA production using inulin as feedstock.

The temperature of growth and sporulation modulates the efficiency of spore-display in Bacillus subtilis.

Background: Bacterial spores displaying heterologous antigens or enzymes have long been proposed as mucosal vaccines, functionalized probiotics or biocatalysts. Two main strategies have been developed to display heterologous molecules on the surface of Bacillus subtilis spores: (i) a recombinant approach, based on the construction of a gene fusion between a gene coding for a coat protein (carrier) and DNA coding for the protein to be displayed, and (ii) a non-recombinant approach, based on the spontaneous and stable adsorption of heterologous molecules on the spore surface. Both systems have advantages and drawbacks and the selection of one or the other depends on the protein to be displayed and on the final use of the activated spore.

Bacillus subtilis builds structurally and functionally different spores in response to the temperature of growth.

Bacterial spores are commonly isolated from a variety of different environments, including extreme habitats. Although it is well established that such ubiquitous distribution reflects the spore resistance properties, it is not clear whether the growing conditions affect the spore structure and function. We used Bacillus subtilis spores of similar age but produced at 25, 37, or 42°C to compare their surface structures and functional properties.
