In recent years, there has been an increasing interest in the remediation of contaminated environments, and a suitable solution is in situ bioremediation. To achieve this, large-scale bacterial biomass production should be sustainable, using economic culture media. The main aim of this study was to optimize the physicochemical conditions for the bi...

The misuse and overuse of antibiotics have led to the emergence of multidrug-resistant microorganisms, which decreases the chance of treating those infected with existing antibiotics. This resistance calls for the search of new antimicrobials from prolific producers of novel natural products including marine sponges. Many of the novel active compou...

One of the most diverse ecological niches for microbial bioprospecting is soil, including that of drylands. Drylands are one of the most abundant biomes on Earth, but extreme cases, such as deserts, are considered very rare in Europe. The so-called Tabernas Desert is one of the few examples of a desert area in continental Europe, and although some ...

Lichens are specific symbiotic organisms harboring various microorganisms in addition to the two classic partners (algae or cyanobacterium and fungus). Although lichens produce many antibiotic compounds such as (+)-usnic acid, their associated microorganisms possess the ability to colonize an environment where antibiosis exists. Here, we have studi...

Abstract: Although many advances have been achieved to treat aggressive tumours, cancer remains a leading cause of death and a public health problem worldwide. Among the main approaches for the discovery of new bioactive agents, the prospect of microbial secondary metabolites represents an effective source for the development of drug leads. In this...

Simple Summary The current study shows that freshwater snails can be considered as new sources for bioactive metabolites, since a novel Streptomyces species 7NS3 produced four active compounds against Gram-positive bacteria. One of the compounds was an angucycline-like aromatic polyketide matched with a known compound, emycin A. Genome mining studi...

BackgroundChelocardin (CHD) exhibits a broad-spectrum antibiotic activity and showed promising results in a small phase II clinical study conducted on patients with urinary tract infections. Importantly, CHD was shown to be active also against tetracycline-resistant Gram-negative pathogens, which is gaining even more importance in today’s antibioti...

Natural products are an important source of novel investigational compounds in drug discovery. Especially in the field of antibiotics, Actinobacteria have been proven to be a reliable source for lead structures. The discovery of these natural products with activity- and structure-guided screenings has been impeded by the constant rediscovery of pre...

The diversity of cultural Actinobacteria in two types of Algerian Sahara environments, including saline environments and date palms rhizosphere, was investigated. In this study, a total of 40 strains of actinomycetes was isolated from different soil samples, using a rehydration and centrifugation method. Molecular identification, based on 16S rRNA ...

This study investigates the decolorization potential of actinobacteria from soil towards toxic triphenylmethane (TPM) dyes, i.e., malachite green (MG), methyl violet (MV), crystal violet (CV), and cotton blue (CB). The actinobacterial isolates were first isolated from fresh soil samples, plated onto actinomycetes isolation agar (AIA), and both live...
