The Human Microbiome Project has begun the process of cataloging our normal bacteria (and archaea) so we can better understand these functions.Figure 4. This scanning electron micrograph shows Clostridium difficile, a Gram-positive, rod-shaped bacterium that causes severe diarrhea. Infection commonly ...
From this observation, it was hypothesized that these Gram-positive (monoderm) bacteria display inherent physiological adaptation to drought as well as a response to plant metabolic changes under drought. Furthermore, some studies suggest that when plant hosts suffer from abiotic/biotic stresses, they...
Titania nanoparticles have a zeta potential that goes from positive to negative as pH increases with zero potential around pH 6 according to Jiang J. et al. 20082. Bacteria are carrying both negative and positive charges with a general dominance towards total negative net charge27. The ...
Indole-3-Acetic Acid and 1-Aminocyclopropane-1-Carboxylate Deaminase: Bacterial Traits Required in Rhizosphere, Rhizoplane and/or Endophytic Competence by Beneficial BacteriaChapter First Online: 06 November 2015 pp 183–258 Cite this chapter Bacterial Metabolites in Sustainable Agroecosystem ...
Lactobacilli are gram positive bacteria that are part of the normal, healthy microbial flora of the vagina as well as the mouth and digestive system. Lactobacilli help fight vaginal infections by producing metabolic byproducts such as hydrogen peroxide (H2O2) and creating an acidic environment. [...

Phytases are widespread in various microorganisms including filamentous fungi, Gram-positive and Gram-negative bacteria and yeasts [87]. Among yeasts, Candida krusei (Issatchenkia orientalis) [88], Schwanniomyces castellii [89], Debaryomyces castellii [90], Arxula adeninivorans [91,92], Pichia...
The Pantoea is defined as aerobic or facultative anaerobic, gram-negative, rod-shaped bacteria, which are typically motile by virtue of peritrichous flagella [2,5]. Bacteria belonging to the genus showed positive reactions for catalase, gelatin and starch hydrolysis tests [6,7,8], and are able...
Their activity, higher against Gram-positive bacteria has been related to their ability to alter cell membranes and disrupt cell walls [21]. Nagayama et al. (2002) assessed the antimicrobial properties of phlorotannins extracted from Ecklonia kurome against a variety of foodborne pathogens, ...
These generally include Lactobacillus, Bifidobacterium, Saccharomyces genera, some strains of Escherichia coli, and some Gram-positive cocci. They should be nonpathogenic and non-toxic, and can be consumed as gel, paste, powder, liquid, or capsule forms, being able to adhere to gut epithelial ...
