    Abstract The rationale of our bioprospecting campaigns is that the extremobiosphere, particularly the deep sea and hyper-arid deserts, harbours undiscovered biodiversity that is likely to express novel chemistry and biocatalysts thereby providing opportunities for therapeutic drug and industrial process development. We have focused on actinobacteria because of their frequent role as keystone species in soil ecosystems and their unrivalled track record as a source of bioactive compounds. Population numbers and diversity of actinobacteria in the extremobiosphere are traditionally considered to be low, although they often comprise the dominant bacterial biota. Recent metagenomic evaluation of 'the uncultured microbial majority' has now revealed enormous taxonomic diversity among 'dark' and 'rare' actinobacteria in samples as diverse as sediments from the depths of the Mariana Trench and soils from the heights of the Central Andes. The application of innovative culture and screening options that emphasize rigorous dereplication at each stage of the analysis, and strain prioritization to identify 'gifted' organisms, have been deployed to detect and characterize bioactive hit compounds and sought-after catalysts from this hitherto untapped resource. The rewards include first-in-a-class chemical entities with novel modes of action, as well as a growing microbial seed bank that represents a potentially enormous source of biotechnological and therapeutic innovation.

    Abstract The development of continuous culture techniques 60 years ago and the subsequent formulation of theory and the diversification of experimental systems revolutionised microbiology and heralded a unique period of innovative research. Then, progressively, molecular biology and thence genomics and related high-information-density omics technologies took centre stage and microbial growth physiology in general faded from educational programmes and research funding priorities alike. However, there has been a gathering appreciation over the past decade that if the claims of systems biology are going to be realised, they will have to be based on rigorously controlled and reproducible microbial and cell growth platforms. This revival of continuous culture will be long lasting because its recognition as the growth system of choice is firmly established. The purpose of this review, therefore, is to remind microbiologists, particularly those new to continuous culture approaches, of the legacy of what I call the first age of continuous culture, and to explore a selection of researches that are using these techniques in this post-genomics age. The review looks at the impact of continuous culture across a comprehensive range of microbiological research and development. The ability to establish (quasi-) steady state conditions is a frequently stated advantage of continuous cultures thereby allowing environmental parameters to be manipulated without causing concomitant changes in the specific growth rate. However, the use of continuous cultures also enables the critical study of specified transition states and chemical, physical or biological perturbations. Such dynamic analyses enhance our understanding of microbial ecology and microbial pathology for example, and offer a wider scope for innovative drug discovery; they also can inform the optimization of batch and fed-batch operations that are characterized by sequential transitions states.

    Abstract This brief introduction is intended to orientate the reader with respect to the principal environmental and historical features of the Atacama Desert, the oldest and continuously driest non-polar temperate desert on Earth. Exploration of its microbiology is relatively recent but both fundamental and applied research activities have grown dramatically in recent years reflecting the substantial interest in its microbial diversity, ecology, biogeochemistry, natural product potential and Mars-analogue properties of this unique and invigorating environment.

    Abstract Interests in the Atacama Desert of northern Chile until very recently were founded on its mineral resources, notably nitrate, copper, lithium and boron. Now this vast desert, the oldest and most arid on Earth, is revealing a microbial diversity that was unimagined even a decade or so ago; indeed the extreme hyper-arid core of the Desert was considered previously to be completely devoid of life. In this Perspective article we highlight pioneering research that, to the contrary, establishes the Atacama as a combination of rich microbial habitats including bacteria that influence biogeochemical transformations in the desert and others that are propitious sources of novel natural products. Many of the Atacama's habitats are especially rich in actinobacteria, not necessarily as dense populations but extensive in taxonomic diversity and capacities to synthesize novel secondary metabolites. Among the latter, compounds have been characterized that express a range of antibiotic, anti-cancer and anti- inflammatory properties to which a variety of bioinformatics and metabolic engineering tools are being applied in order to enhance potencies and productivities. Unquestionably the Atacama Desert is a living desert with regard to which future microbiology and biotechnology research presents exciting opportunities.

    Abstract A set of oligonucleotide primers, Rubro223f and Rubro454r, were found to amplify a 267 nucleotide sequence of 16S rRNA genes of Rubrobacter type strains. The primers distinguished members of this genus from other deeply-rooted actinobacterial lineages corresponding to the genera Conexibacter, Gaiella, Parviterribacter, Patulibacter, Solirubrobacter and Thermoleophilum of the class Thermoleophilia. Amplification of DNA bands of about 267 nucleotides were generated from environmental DNA extracted from soil samples taken from two locations in the Atacama Desert. Sequencing of a DNA library prepared from the bands showed that all of the clones fell within the evolutionary radiation occupied by the genus Rubrobacter. Most of the clones were assigned to two lineages that were well separated from phyletic lines composed of Rubrobacter type strains. It can be concluded that primers Rubro223f and Rubro454r are specific for the genus Rubrobacter and can be used to detect the presence and abundance of members of this genus in the Atacama Desert and other biomes.
