Biodegradation of livestock processing waste is one the more cost-effective, ecologically safe recycling methods thatmay preserve nutritional content and key amino acids useful in animal feed production. Here, we determined thebiodegrading potentials nonconventional feedstuffs using a combination bacteria (Bacillus subtilis) fungi(Fusarium sp.). Five types (feather meal, hair waste, egg membran...

Abstract As water resources become increasingly scarce, the concept of reuse is gaining importance. Recently, attention has been paid to use rainwater as an alternative resource. Part this study, laboratory-scale experiments were conducted evaluate effectiveness and efficiency ultrafiltration process. The aim research was assess influence pollutants from various roof coverings on process occurr...

Optically active bionanocomposite membranes composed of polyester(PE) and cellulose /silica bionanocomposite (BNCs) are a novel method to enhance gas separation performance. Commercially available silica nanoparticles were modified with biodegradable nanocellulose through ultrasonic irradiation technique. Transmission electron microscopy (TEM) analyses showed that the cellulose/silica composite...

The aim of this study was to compare invasive and non-invasive strains of Shigella flexneri isolated from Tehran by a 120 kDa protein band by SDS-PAGE, electron microscopy of cell culture and Congo red dye methods. Methods: S. flexneri strains were isolated by standard bacterial methods from fecal specimens of children attending to the 3 children’s hospitals. Phenotype analysis for screening v...

Membrane remodeling of targeted host cells is a necessary action for successful bacterial subversion the host. This includes formation membrane ruffles pathogen entry or reprogramming endomembranes during intracellular trafficking. The importance BAR domain-containing proteins in such diverse cellular functions highlights their hijacking by pathogens. Given implication variety functions, as end...

Many outer membrane proteins (OMPs) in Gram-negative bacteria possess known -barrel three-dimensional (3D) structures. These proteins, including channel-forming transmembrane porins, are diverse in sequence but exhibit common structural features. We here report computational analyses of six outer membrane proteins of known 3D structures with respect to (1) secondary structure, (2) hydropathy, a...

Outer-inner membrane vesicles (O-IMVs) were recently described as a new type of membrane vesicle secreted by the Antarctic bacterium Shewanella vesiculosa M7T. Their formation is characterized by the protrusion of both outer and plasma membranes, which pulls cytoplasmic components into the vesicles. To demonstrate that this is not a singular phenomenon in a bacterium occurring in an extreme env...

The outer-membrane proteins (OMPs) of bacteria function as the dynamic interface between the bacterium and its surroundings and are involved in maintenance of cell structure, binding a variety of substances, adhesion to other cells, and regulation of transport of both nutrients and bactericidal agents. There is a vast amount of information about aerobic OMPs and their roles in immunogenicity, v...

UNLABELLED Bacteria organize many membrane-related signaling processes in functional microdomains that are structurally and functionally similar to the lipid rafts of eukaryotic cells. An important structural component of these microdomains is the protein flotillin, which seems to act as a chaperone in recruiting other proteins to lipid rafts to facilitate their interaction. In eukaryotic cells...
