Advance studies and recent researches usually deal with the various phases and sections of science in order to comprehend the dynamic, ever-changing and evolutionary world as well as the individuals and microorganisms that live in it. Researches have significantly evolved for more than a century. Though previous researches or experimental studies may not be as advanced or highly technological as compared to the recent studies still those researches provided lots of information and details as to how people will survive. Different studies and experiments on diseases and their treatments have also been implemented as well as the various studies on microorganisms and their never ending activities, evolutions, mutations and reproduction. These microorganisms actually inhabit more than the human populations. It is also a fact that the human bodies constitute microorganisms of different kinds, the good ones as well as the bad ones. Not only microbes are being studied, minerals and other elements that have linkages to these microorganisms as to their interactions and productions are also being carefully analyzed in order to provide measures against harmful microorganisms and to boost the therapeutic mechanisms of the useful microorganisms.

The article actually discussed on the microorganisms that were discovered in extreme environments such as the volcanoes, and other unexpected places. There are metabolically energetic microbial population that were uncovered in the subsurface basalt aquifers, granite batholiths and the oceanic crust, which were never been thought places to find microorganisms. Comprehending how these populations flourish in what commonly known as extremely oligotrophic conditions is something to watch out for. Innovative acts on this subject or area is being facilitated by both new methods and fresh ideas with advanced technology. The researchers aspire to convey novel ideas into the environmental control of microbial diversity and physiology, and to aid in the analysis of fossil records and exobiology through ascertaining the movement of single cells and their populations react at the molecular degree with one another together with their surrounding, and with the possible sources of energy.

The researchers purpose to determine and comprehend the procedures by which microorganisms obtain their energy through their interactions with metals and minerals. The article cited as an example of this interaction the process of chemolithoautotrophy, which is vital due to the limited supply of labile carbon such as deep-sea hydrothermal vents, terrestrial geothermal features, and high altitude, xeric settings. In this part, volcanic substances are among the most ever-present types of rocks on the surface of the Earth yet how microorganisms react with a volcano specifically on new or reasonably weathered lava has been vaguely missed. One of the most admirable terrestrial sites to examine and study the microbial population structure under extremely nutrient-restricted condition is the place called Hawaii Volcanoes National Park or HVNP. Alongside with fumaroles, gasses and rainwater, the sight is suggestive of circumstances that existed on most of early Earth. The researchers made a hypothesis that constituents of the microbial populations in that place obtain their energy through oxidizing the elements in lava such as Iron and Magnesium, and that necessitate nutrients from the disbanding of primary minerals. The procedure they utilize to take possession and change the host rocks can be specific to terrestrial chemolithoautotrophs or can be sophisticated.

The article also mentioned that lava caves in Kilauea are an appealing locale to study microbial interactions with the surroundings. The rock substrates are extremely young, ultraviolet exposure alterable, and water accessibility is limited. Such factors in terms of phylogeny, physiology, genetic expression, production rates, nutrient cycling and lithoautotrophic variation of basalt substrates that may affect cave microbial populations, are some of the queries that the researchers aimed to answer. The researchers expect to find new microbes and novel biogeochemical functions for known microbes through examination of natural microbial populations as well as the inhabitation of substrates in the site and in the laboratory, and through cell specific and oligotrophic culturing methodologies.
