Steroids are abundant molecules in nature, and various microorganisms evolved to utilize steroids. Thermophilic actinobacteria play an important role in such processes. However, very few thermophiles have so far been reported capable of degrading or modifying natural sterols. Recently, genes putatively involved in the sterol catabolic pathway have been revealed in the moderately thermophilic This chapter discusses desert actinobacterial diversity and their bioactive compound production. For isolation of soil actinobacteria, selection of media is important for understanding their ecological properties and for discovery of novel strains which can produce useful bioactive secondary metabolites. The macroalgae surface allows specific bacterial communities to colonize, resulting in complex biological interactions. In recent years, several researchers have studied the diversity and function of the epiphytic bacteria associated with algal host, but largely these interactions remain underexplored. In the present study we analysed the cultivable diversity and polymer degradation potential
Marine actinobacteria research Marine microbiology is developing strongly in several countries with a distinct focus on bioactive compounds. Analysis of the geographical origins of compounds, extracts, bioactivities and actinobacteria up to 2003 indicate that 67% of marine natural products were sourced from Australia, the Caribbean, Indian Ocean,
Actinobacteria are present in various ecological habitats and marine environments [ 2] and to cope with the environmental stress, marine microorganisms have developed a complex stress management for their survival, which is being unrevealed for multiple purposes [ 3 ].

Biomolecules produced by marine actinomycetes have peculiar chemical structures that could be utilized to produce novel drugs to combat pathogens with antimicrobial resistance. The objective of the present investigation was to identify antagonistic properties of marine actinomycetes' toward multidrug resistant bacterial pathogens affecting the urinary system. Here, 58 actinomycetes isolates
The research for new strains of Actinobacteria producing new antibiotics is one of the strategies, as some authors claim that this group of Actinobacteria is a bioproduct deposit, moreover marine Actinobacteria are also considered a good source of pharmaceutical bioproducts.
Additionally, Actinobacteria species were more abundant in the water samples representing 22-52% of all reads during the stratification period. Due to the complete mixing conditions in the lake, a homogenized bacterial community structure was observed in the lake with minor spatial changes, and a clear divergence was observed between
Key Points. Actinobacteria is one of the dominant phyla of the bacteria. Actinobacteria include some of the most co
