The British Microbial Biodiversity Association (BMBA) aims to provide a link between and within UK Universities and Bioindustries in order to promote the investigation, preservation and rational exploitation of global microbial biodiversity.
The British Microbial Biodiversity Association incorporates the UK Extremophile Network (UKEN) whose role is to promote interactive research on extremophilic micro-organisms.

NEWS !!!Members of the Association visited the British Protectorate of Montserrat in March of 1996. The expedition was funded by the Biotechnology and Biological Sciences Research Council (BBSRC) to investigate the microbial diversity of the Montserrat soufrieres, the thermal springs associated with the island's volcano. For a fuller report on the expedition and a photographic record, click here.
In June 1996, BMBA sent a team of microbiologists to monitor and sample the Wooton Basset (Gloucestershire, UK) mud springs. These unusual sites are more than 120 meters deep and emit a steady flow of fluidised mud at a rate of several cubic meters per day. The BMBA scientists are interested in the anaerobic microbiology of the mud flow and the possible links between this source and the deep terrestrial biosphere. For a fuller report on the expedition and photographic record, click here.
Dr. Judy McArdell, while on vacation in Bermuda in August 1996 undertook a preliminary evaluation, for microbiological purposes, of these geologically unique caves which support rare macrobiotopes. The nearest evolutionary relatives of these biotopes are found in the Pacific, giving rise to speculation of an ancient subterranean link between the relatively isolated landmass of Bermuda and the Pacific. The caves are currently under environmental threat and dependent on the data, a further evaluation may be required which is in discussion with the UK Dependent Territories Conservation Forum and the Foreign and Commonwealth Office.
BMBA is currently planning an expedition to investigate the Chagos islands in the Indian ocean. These islands are believed to represent one of the most unpolluted areas in the world. Watch this space!

Introduction
Montserrat, a British Dependency located in the Lesser Antilles islands of the Caribbean archipelago, is a small island dominated by its volcanic history. The volcanic peak, currently active, supports a variety of hydrothermal features on its flanks which, together with the rich tropical terrestrial and marine environments, offer a spectacular diversity of macro- and microbiotopes.
The 30 year cycle of volcanic activity on Montserrat adds an interesting dimension to the hydrothermal biotopes. Changes in temperature, liquid volumes, gas content and mineralisation induced by fluctuating volcanic activity may have a profound influence on the evolution of microbial molecular resistance mechanisms.
The BBSRC funded UK Extremophile Expedition of March 1996 visited, mapped and sampled the hydrothermal regions of Montserrat, discovering a unique combination of thermal, saline, pH, mineral and redox gradients which support extremophilic microbial populations. The variability and proximity of these biotopes offer excellent opportunities for developing studies on microbial evolutionary mechanisms, particularly with respect to temperature, halophilicity, metal leaching and toxic metal resistance. The following examples represent the preliminary assessments of the UK Extremophile Expedition team of the possible targets for forced evolution studies.
Temperature Gradients
Galway's soufriere is characterised by a central thermal stream with an emission temperature above 95C and a cooling profile of some 70C over 200m. Lateral thermal inputs and flow fluctuations resulting from natural precipitation will result in periodic thermal fluctuations of 30-40C. Sites at points of thermal intermixing and along longitudinal profiles offer biotopes where both thermophilic and mesophilic micro-organisms may be subject to strong selective pressures for resistance to temperature fluctuations. Continuous on-site temperature monitoring supported by laboratory investigations of microbial thermal resistance and Arrhenius behaviour would be a valid approach to determining the significance of such adaptive pressures.
pH
pH values in hydrothermal emission fluids at different sites range from 1.2 to 8.1. In some sites, particularly Galway's soufriere, streams with widely divergent pH values mix to give intermediate pH values. For example, an acidic stream (pH 1.8) mixes constantly with the neutrophilic primary flow, both at thermophilic temperatures. At the point of mixing, non-laminar flow patterns will impose continuous and substantial pH fluctuations. Such sites may harbour pH adaptive extremophiles, potential targets for studies of modified H+ and Na+ transport proteins and membrane protein pH-dependent stability.
Salinity
Hot Water Pond is situated on the Western shoreline of Montserrat and is characterised by a number of saline hydrothermal sources. Variations in salinity resulting from changes in both terrestrial run-off volumes and saline ground-water evolution rates (in addition to storm driven sea-water ingress) may impose periodic fluctuations in both sodium, chloride and other salts. This site is also particularly interesting in having a high heterotrophic nutrient input.
Redox
On-site analysis of hydrothermal fluids in Galway's and Gages soufrieres showed that closely associated hydrothermal fluids contained widely divergent redox values (from +500 to -400). The consequences with respect to the oxidation states of potential autotrophic substrates and the resultant diversity of autotrophic and heterotrophic micro-organisms are particularly significant. Such sites, together with regions where high and low redox hydrothermal fluids mix, offer enormous potential for physiological and adaptation studies.
Metal ions
The hydrothermal fluids at both Galway's and Gages soufrieres are highly mineralised, showing high and varying concentrations of Fe (II/III) together with significant concentrations of Cd, Zn, Mn and other metals. Preliminary microbial isolations have identified a number of novel autotrophic Sulfolobus strains capable of growing on metal sulphides (Paul Norris, unpubl. results).
Experimental results
Detailed analytical results of the Montserrat extremophilic site are shown in Table 1. Results from the preliminary microbial identification studies are shown in Table 2. This listing will be updated with more data as it becomes available.

General Description
Wootton Bassett Mud Springs are a ten minute walk by foot alongside a canal and across agricultural land. The springs, of which all were sampled, are sectioned off by barbed wire fencing of approximately 60 square metres within which the land resembles a wooded area of wild grass, shrubs, trees within a small stream flowing through it from east to west close to the southern edge of the area.
All surface temperature measurements varied due to the increasing heat of the sun. Ambient temperature was about 25C. Due to the nature of the samples a modified ATP procedure had to be undertaken.
Within the area there are five main sites of mud spring activity of which site 1 can be subdivided into three separate mud springs. data is presented for site 1a only as a representative example of all sites.
Site 1
Three separate mud springs (Site1a - Site 1c) located by a dead tree in a clearing. Each spring measured approximately 3/4 of a metre in diameter covering a distance of approximately 4 metres in total.
Navsat Reading: 51D 31M 96S N and taken approx. 2 metres south from site 1a: 001D 53M 36S W
Site 1a
Site 1a measured 12.8 metres from Site 2 on a bearing of 326 degrees and was the nearest of the Site 1 grouping to Site 2.
Surface Temperature: 22.8C (reading taken at noon) Temperature at depth: 3-5cm 21.1C 20cm 18.6C 40cm 15.8C 60cm 15.7C 80cm 15.6C 100cm 15.6C 120cm 15.3C 140cm 15.2C 160cm 15.1C 180cm 15.0C 200cm 12.3C (varying down to 11.9C) pH: 7.39 Conductivity: 1798 ATP Surface sample: 53 RLU ATP ~ 2 metre depth: 58 RLU
