Antimicrobial peptides are diverse group of biologically active molecules with multidimensional properties. In recent past, a wide variety of AMPs with diverse structures have been reported from different sources such as plants, animals, mammals, and microorganisms. The presence of unusual amino acids and structural motifs in AMPs confers unique structural properties to the peptide that attribu...

The violet pigment violacein is an indole derivative, isolated mainly from bacteria of the genus Chromobacterium, which exhibits important antitumoral, antimicrobial and antiparasitary properties. Furthermore, the formulation of violacein in different polymeric carriers developed so far offers alternative approaches to overcoming physiological barriers and undesirable physicochemical properties...

mycelium and aerial hyphae. Spiral spore chains of 10 to 30 or more spores were observed at the tips of aerial hyphae on the various ISP agar media. Fragmentation of substrate mycelium, sclerotium and sporangia-like vesicles was not observed. The cultural characteristics of strain A-230 on various agar media are summarized in Table 1. The physiological properties and the utilization of carbohyd...

The material response discussed in the previous chapters was limited to the response of elastic materials, in particular to linearly elastic materials. Most metals, for example, exhibit linearly elastic behavior when they are subjected to relatively low stresses at room temperature. They undergo plastic deformations at high stress levels. For an elastic material, the relationship between stress...

The endophytic fungus is have rich source of secondary metabolites which act as biological active agent in the higher plants. The fungal derivatives play vital part in human life and their compounds are the source of drug for cancer, microbial and viral diseases. The natural compounds from the endophytes acts as growth inhibitor of plant pathogenic organism. Endophytes are rich sources of natur...

silver nanoparticles (nps) have been the subjects of researchers because of their unique properties ( e.g., size and shape depending optical, antimicrobial, and electrical properties). a variety of preparation techniques have been reported for the synthesis of silver nps; notable examples include, laser ablation, gamma irradiation, electron irradiation, chemical reduction, photochemical methods...
