Isolation and Characterisation of Actinobacteria from Algerian Sahara Soils with Antimicrobial Activities

Isolation and Characterization of Actinobacteria from Algerian Sahara Soils with Antimicrobial Activities

Extreme ecosystems can be a source of untapped microorganisms to produce novel bioactive compounds of industrial interest. Consequently, in this work, 32 actinomycetes were isolated from 6 soil samples collected from Algerian Sahara in searching for untapped producers of novel antimicrobial compounds. All the isolates were further subjected to antimicrobial screening against pathogenic bacteria...

Introducing antimicrobial exopolymer-producing actinobacteria from soils of Iran

Exopolymers (EPS) are high-molecular-weight polymers secreted by some micro-organisms and have several applications in food, pharmaceutical, packaging and agricultural industries, as well as medicine. Actinobacteria are valuable bacteria in biotechnology and many commercial drugs such as antibiotics, antioxidants and immune-suppressant agents are derived from Actinobacteria. Recently, their oth...

Isolation and Characterisation of Anti-diabetic Pharmacological Activities of Phytoestrogens

Screening for Genes Coding for Putative Antitumor Compounds, Antimicrobial and Enzymatic Activities from Haloalkalitolerant and Haloalkaliphilic Bacteria Strains of Algerian Sahara Soils

Extreme environments may often contain unusual bacterial groups whose physiology is distinct from those of normal environments. To satisfy the need for new bioactive pharmaceuticals compounds and enzymes, we report here the isolation of novel bacteria from an extreme environment. Thirteen selected haloalkalitolerant and haloalkaliphilic bacteria were isolated from Algerian Sahara Desert soils. ...

Antibacterial and antioxidant activities of three endemic plants from Algerian Sahara.

BACKGROUND Saharan plants are known by their high content of antioxidant products like phenolic compounds due to the extreme climatic conditions. They constitute the basis of treatments used by local population for various diseases. The purposes of this study were to measure the total phenolic compounds and total fl avonoid compounds, to determine antioxidant capacity, and to evaluate the antib...

Diversity and Antimicrobial Potential of Culturable Actinobacteria from Desert Soils of Saudi Arabia

The present investigation Saudi Arabian desert actinobacteria have been studied for discovery of novel actinobacteria and also useful new sources for bioactive metabolites. Soil samples were collected from 10 different places in Riyadh province of Saudi Arabia. The maximum actinobacterial count 21.8x10 was recorded in Hazlullah soil sample and minimum 1.6x10 was recorded in Al-Kharj soil sample...
