Hydrophobins are small proteins secreted by fungi, which self-assemble into amphipathic membranes at air-liquid or liquid-solid interfaces. The physical and chemical properties of some hydrophobins, both in solution and as a biofilm, are affected by poly or oligosaccharides. We have studied the interaction between glucose and the hydrophobin Vmh2 from Pleurotus ostreatus by spectroscopic ellips...

Dental caries is an infectious and transmissible disease, in which many genetic, environmental and behavioral risk factors interact. The mutans streptococci (MS), mainly Streptococcus mutans and Streptococcus sobrinus are the microorganisms most strongly associated with this disease. The main virulence factors associated with MS cariogenicity include adhesion, acidogenicity and acid tolerance. ...

Graphene-modified materials have captured increasing attention for energy applications due to their superior physical and chemical properties, which can significantly enhance the electricity generation performance of microbial fuel cells (MFC). In this review, several typical synthesis methods of graphene-modified electrodes, such as graphite oxide reduction methods, self-assembly methods, and ...

land use change of forest ecosystems in northern iran changes the soil quality of paresar (gilan province) and gorgan (gorgan province) regions. in order to study changes in some biological soil quality indices due to land use change from forest to cultivated lands, composite soil samples from two depths (0-20 and 20-40 cm) were taken from paresar and gorgan regions and urease, alkaline and aci...

Surface-active agents or surfactants are amphiphilic compounds derived naturally chemically synthesized. Natural so-called biosurfactants can be obtained from bacteria, yeasts, and fungi as well plants. Due to their hydrophilic hydrophobic molecules, offer the ability reduce surface interfacial tension create microemulsion between aqueous organic phases. Many studies have suggested a better sub...

Science This study investigates the effect of chitosan and rosemary essential oil on properties of starch films and peanut were packaged in them. Materials and Methods: In this study, composite films based on starch containing 0, 2, 4, 6 and...

Wound healing continues to pose a challenge in clinical settings. Moreover, wound management must be performed properly and efficiently. Acute involves multiple cell divisions, new extracellular matrix, the process of formation, such as growth factors cytokines, which are released at site regulate process. Any changes that disrupt could cause tissue damage prolong Various factors, microbial inf...
