1. Diversity of Endophytic and Epiphytic Bacteria From Sugarcane in Khuzestan, Iran
Abstract Diverse microorganisms are living as endophytes in plant tissues and as epiphytes on plant surfaces in nature. Commercial formulations of bacteria antagonist to plant pathogenic microbes and ice nucleation active bacteria have been utilized as an environmentally safe method to manage plant disease and to prevent frost damage respectively. Bacteria w

3. Lipopeptide production by Bacillus subtilis R1 and its possible applications
Abstract The possible application of a bacterial strain - Bacillus subtilis R1, isolated from an oil contaminated desert site in India, as biocontrol agent and its biosurfactant in microbial enhanced oil recovery are discussed. The biosurfactant production in minimal medium was carried out at different temperatures and salt concentrations, where it produced

4. Screening and characterization of endophytic Bacillus and Paenibacillus strains from medicinal plant Lonicera japonica for use as potential plant growth promoters
Abstract A total of 48 endophytic bacteria were isolated from surface-sterilized tissues of the medicinal plant Lonicera japonica, which is grown in eastern China; six strains were selected for further study based on their potential ability to promote plant growth in vitro (siderophore and indoleacetic acid production). The bacteria were characterized by phy

5. Characterization and mapping of a spotted leaf mutant in rice (Oryza sativa)
Spotted leaf mutant belongs to a class of mutants that can produce necrotic lesions spontaneously in plants without any attack by pathogens. These mutants have no beneficial effect on plant productivity but provide a unique opportunity to study programmed cell death in plant defense responses. A novel rice spotted leaf mutant (spl30) was isolated through low

6. Inhibition of Saccharomyces cerevisiae Pdr5p by a natural compound extracted from Brazilian Red Propolis
Multidrug resistance of cancer cells and pathogenic microorganisms leading to the treatment failure of some forms of cancer or life-threatening bacterial or fungal infections is often caused by the overexpression of multidrug efflux pumps belonging to the ATP-binding cassette transporters superfamily. The multidrug resistance of fungal cells often involves t

7. Mecanismos envolvidos com a sobrevivência de Xylella fastidiosa em condições de estresse e efeito de N-Acetil-L-Cisteína em seu biofilme / Mechanisms involved in Xylella fastidiosa survival under stress conditions and effect of N-Acetyl-L-Cysteine on its biofilm
Xylella fastidiosa is a Gram-negative bacterium that causes several diseases in different plant species, including citrus variegated chlorosis (CVC) in sweet orange (Citrus sinensis L. Osbeck), whose economic damage is of millions of dollars annually. The symptoms development has been associated with the blockage of xylem vessels caused by bacterial biofilm

8. Probiosis: concepts and prospects
The use of probiotics in animal and human feeding has been a subject of increasing interest both for the academia and the industry, mostly due to their potential positive effects on health and profitability. However, the knowledge on the composition of bacterial gastrointestinal communities in humans and animals, as well as its respective nutritional require

9. Molecular battles between plant and pathogenic bacteria in the phyllosphere
The phyllosphere, i.e., the aerial parts of the plant, provides one of the most important niches for microbial colonization. This niche supports the survival and, often, proliferation of microbes such as fungi and bacteria with diverse lifestyles including epiphytes, saprophytes, and pathogens. Although most microbes may complete the life cycle on the leaf s

11. A comparative evaluation of antibacterial potential of some plants used in indian traditional medicine for the treatment of microbial infections
A comparative in vitro antibacterial potential of extracts (aqueous and ethanol) of five important medicinal plants (Aegle marmelos, Azadirachta indica, Terminalia chebula, Mangifera indica and Ocimum sanctum) were investigated using microbial growth inhibition assays against the common human pathogenic bacteria (Staphylococcus aureus, Pseudomonas aeruginosa

12. Diversity and genetic characterization of endophytic microbial communities associated with sugarcane / Diversidade e caracterização genética de comunidades microbianas endofíticas associadas à cana-de-açúcar
In Brazil, the sugarcane is one of the most important cultivated crops. The sugarcane has received increased interest in the last years because of increase of the cultivated area and ethanol production to be used as biofuel. Considering its economical importance and the possibility of the use of the genetically modified plants; this crop has become the aim o
