Background: Bryophytes, the previous land plants posses medicinally important bioactive compounds but with little information. Traditionally the bryophytes plants posses some bioactive components and therefore used throughout the world as drugs and remedies to cure the various diseases.  Objectives: Evaluation of antimicrobial effect of mentioned bryophytes on some pathogenic microorganisms. ...

Background and objectives: Despite the vast production of new antibiotics in the last three decades, resistance to these drugs by microorganisms has increased and essential oils (EOs) have been recognized to possess antimicrobial properties. Methods:  In the present study, EOs obtained from aerial parts of Thymus vulgaris L., Lavandula angustifolia Mill., Rosmarinus offici...

Screening of microorganisms for the production of novel antibiotics has been intensivelypursued for many years by scientists. Actinomycetes have the capability to synthesize manydifferent antibiotics. A total of 69 actinomycete isolates were recovered from soil samplescollected from Alborz Province. Selected colonies (rough, chalky) of actinomycetes werepurified. All screened isolates were iden...

Most turfgrass managers do not have a strong understanding of turfgrass soils, particularly the biological aspects. Certainly most know that living things, such as worms and insects can reside in soil, but they’re not sure where in the soil they live or what they live on. In fact, it might be safe to assume that most turfgrass managers consider soil to be a mysterious world below the turfgrass ...

With the respect to microbial flora, the oral cavity is one of the most densely populated sites of the human body. The environmental diversity of the oral cavity promotes the establishment of distinct microbial communities, such as supragingival plaque, subgingival plaque and tongue coating. The properties of the environment determine which microorganisms can occupy a site, while the metabolic ...
