L-ASPARAGINASE is an anti-neoplasm agent. This agent is classified as an enzyme compound. L-asparaginase is used in medicine as well as in the food industry. Microbial strains that are producing L-Asparaginase can be found in many habitats such as soil. The aim of this study was to find isolates producing L-asparaginase enzyme with high ability to inhibit cancer cells. Bacteria of the Actinobacter family were isolated from the soil samples around the roots of the plants in the actinomycet isolat...

Objective: To identify the biodiversity of Nocardia species isolated from the environments of Tehran hospitals via phenotypic and PCR molecular methods. Methods: A total of 236 samples were collected from the transplantation and cancer centers of five Tehran hospitals, and the presence of Nocardia was identified by using standard protocols. Conventional tests were used for preliminary identification, and PCR amplification of the 598 bp amplicon of the 16S rRNA and sequence analysis of 16S rRNA w...

Lut desert is situated in one of the extremely arid climatic zones of Iran and is one of the hottest deserts in our plant with the extreme fluctuation of temperature over a day. The main objective of this study is to characterize the diversity of the culturable actinomycetes and preliminary evaluation of their extracts as antimicrobial components on drug resistant pathogens. Twenty-four soil samples were collected, successively diluted and inoculated into the different culture media to support t...

Background: Nocardia species are nocardiosis agents particularly in immune disorder patients with the clinical manifestations including fatigue, malaise, weight loss, cough, and dyspnoea. Due to time - consuming bacterial culture and insufficient phenotypic tests alone, rapid molecular assays for the diagnosis of Nocardia are essential. The primary objective of this study was the analysis of the polymerase chain reaction - restriction fragment length polymorphism (PCR - RFLP) and PCR sequencing ...

Background: Propolis is one of the most potent natural antibiotics. Propolis as an active natural substance is attractive due to its antimicrobial properties. Propolis has been used in folk medicine for centuries. It is known that propolis possesses anti- microbial, antioxidative, anti-ulcer and anti-tumor activities. Therefore, propolis has attracted much attention in recent years as a useful or potential substance used in medicine. Objectives: The purpose of this study was to verify the activi...

Background: The genus Nocardia is Gram-positive, aerobic filamentous bacilli and saprophytic micro-organisms that can be isolated from freshwater, salt water, dust and decaying vegetation especially the soil. This study aimed to investigate the several media for to determine a suitable culture media with the ability to better for the isolation of Nocardia from soil. Methods: In this study, 400 soil samples were collected from different areas from Iran. The soil samples were then cultured on the ...
