[ 1 ] - Isolation of biologically active Actinomycetes from untouched soils: a case study from Karaj district, Iran
Actinomycetes are a source of a broad variety of secondary metabolites with diverse biological activities, such as antifungi, antibiotics and antitumorals; many of which have been developed for clinical use. In this study, 34 actinomycetes from untouched soils were isolated from Alborz Province-Iran. Evaluation ofantifungal and anti bacterial activities of these isolates, demonstrated the capab...
[ 2 ] - Antibacterial activity of some actinomycetes isolated from soils of Alborz province, Iran
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...
[ 3 ] - سنجش زیستی و غربال‌گری مولکولی آنزیم پکتیناز در باکتری‌های نمک‌دوست جداشده از دریاچه‌های نمکی ایران
مقدمه: پکتیناز یا آنزیم‌های پکتینولاتیکی، کمپلکس آنزیمی شامل سه آنزیم پکتین‌متیل‌استراز (EC.3.1.1.11)، پکتین‌لیاز (EC.4.2.2.2) و پلی‌گالاکتوروناز (EC.3.2.1.15) هستند که باعث تجزیه پکتین موجود در دیواره سلول‌های گیاهی می‌شوند. این آنزیم‌ها مصرف‌های صنعتی بسیاری دارند که تعدادی از آنها در شرایط حاد از نظر دما، اسیدیته و غظت نمک فعال هستند. در پژوهش حاضر، به بررسی و شناسایی باکتری‌هایی پرداخته شد ...
[ 4 ] - Interspecies interactions of halophilic and halotolerant actinomycetes: An example from a salt
Interspecies interaction of actinomycetes will express new gene clusters and may therefore affect the pigmentation, sporulation and production of secondary metabolites. Actinomycetes strains were isolated from Howze Soltan Salt Lake. Binary actinomycete interaction assay was conducted to evaluate its effect on colony morphology and antibiotic production. The molecular identification of the indu...
