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...
متن کاملNOTE Studies of the Biological Characteristics of Some Halophilic and Halotolerant Actinomycetes Isolated from Saline and Alkaline Soils
Microorganisms found in extreme environments have attracted a great deal of attention, due to the production by such microorganisms of various natural compounds and their specialized mechanisms for adaption to extreme environments1-4). But relatively little research work has been done on actinomycetes found in extreme environments5). For example, the nutritional requirements of actinomycetes un...
متن کاملPectinase Activity of some Micromycetes Isolated from Agricultural Soils
Pectinases have multiple nature and various forms which are necessary for the hydrolysis of pectin in several conventional industrial and natural processes. In this investigation fourteen fungal strains which isolated from agricultural soils ,were screened for pectinase activity. Pectinase activity were measured in vitro by assaying released reducing sugar from pectin as sole carbon source. Asp...
