Living organisms require trace amounts of some heavy metals including copper, lead, magnesium, vanadium, zinc etc. Human activities have influenced bio-chemical and geological cycles. Metal ions become toxic in nature when they are beyond tolerance limit. In aquatic ecosystem, fishes and microbes have close, intimate and unseparated contact from the embryonic to adult stage. Bioremediation is therefore an eco-friendly and efficient method of reclaiming environments contaminated with heavy metals by making use of the inherent biological mechanisms of microorganisms and plants to eradicate hazardous contaminants. Microbes play a key role in controlling the speciation and cycling of metals in water. Bio-availability, toxicity and reactivity of metals is greatly influenced to have a better understanding of the major factors that link microbial activity to the bio-geo-chemistry of metals. Micro-organism and other natural products plants and animals and there by- products capable of cycling metals for bio-remediation of contaminated site without any side effect on environment. This investigation discusses the toxic effects of heavy metal pollution and the mechanisms used by microbes for environmental remediation. It also emphasized the importance of modern techniques and approaches in improving the ability of microbial enzymes to effectively degrade heavy metals at a faster rate, highlighting recent advances in microbial bioremediation for the removal of heavy metals from the environment.

This article summarises regarding microbial transformation of steroids which contains different types like Oxidation- in which the alcohols are oxidised to form ketones, Hydroxylation- in this the mycobacterium flavobacterium dehydrogenans helps in hydrolysis, Dehydrogenation, Epoxidations which is a sparse process, Ring a Aromatization, Oxidation to ketone through hydroxylation, Ring a Aromatization ,Degradation of steroid nucleus, Oxidation of alcohols to ketone, Side chain cleavage of steroids, Decarboxylation of acids, Reduction in this the Aldehyde and ketone to alcohol, Hydrolysis, Isomerisation, Resolution of racemic mixture, Other reactions, Esterification were explained.
Every person has their own microbiome, which is distinct from everyone else's. Each is made up of a variety of bacterial, fungal, and viral species that can be found on all body surfaces, including the skin, mucous membranes, and the gastrointestinal system in particular.
Numerous infectious illnesses produced by bacteria that seldom cause disease in normal, healthy immunocompetent hosts emerged in the late twentieth century. The development of these illnesses demonstrates that a conventional notion of pathogenicity and virulence fail to account for the reality that microbial pathogenesis is influenced by both the bacterium and the host. To overcome this barrier to studying host–microbe interactions, we offer the 'damage-response' framework, a novel theoretical paradigm for understanding microbial pathogenesis.
The majority of Indian consumers of drinking water are aware that chemicals are employed in the treatment process to ensure that the water is safe to ingest. However, people may be unaware that the usage of certain of these chemicals, such as chlorine, can result in the development of harmful byproducts that are not regulated.
Microbiologists at Washington University School of Medicine in St. Louis have recognized antibodies that shield animals from sickness as a result of alpha viruses. The antibodies functioned for each alpha virus tested, which means they doubtlessly should shape the idea of remedies a template for a normal vaccine.
Scientific study of microorganisms is known as Food Microbiology, its used in both in food and production of food. This incorporates microorganisms that defile food, just as those utilized in its creation; for instance to produce, cheddar Cheese, yogurt, and wine.
Food production has been increased as a result of the fast adoption of biotechnological techniques that allow for the quick discovery of new chemicals and microbes, as well as the genetic enhancement of established species. Microorganisms have never been more prevalent in fields such as agriculture and medicine in history, save as wellknown villains. Currently, however, different agricultural crops require helpful microbes such as plant growth promoters and controllers for phytopathogens, and many species are utilised as bio-factories for essential pharmaceutical compounds.
The microorganisms that dwell in the digestive systems of humans and other animals, including insects, are known as gut microbiota. They include bacteria, archaea, and microscopic eukaryotes.
Fingolimod (FTY720) is a sphingosine-1-phosphate-receptor modulator that Is administered orally, which is currently being evaluated for the multiple sclerosis treatment.
A Fungal Species Metarhizium anisopliae is a genetically engineered fungus who carries a human anti malaria antibody which is highly effective for killing malaria. This is natural malaria killer species. To make this species for effective for killing malaria researcher engineered a gene which derived from a spider.
Sugarcane bagasse pith is well-known for its usage as a solid substrate for fungi and microbial development, as well as a source of microorganisms that may be separated from it. Pith has also been utilised in soil bioremediation as a bulking agent. Bagasse pith has recently been used for bioethanol synthesis, which involves pretreatment, hydrolysis, fermentation, and dehydration.
A microbial biosensor is an analytical instrument with a biologically integrated transducer that provides a quantifiable signal indicating the analytic concentration. This approach is suitable for analysing extracellular substances and the environment, as well as for metabolic sensory control. Although microbial biosensors show potential for use in a variety of detecting applications, they have certain limitations. Although microbial biosensors show potential for use in a variety of detecting domains, significant drawbacks remain, including poor selectivity, limited sensitivity, and impractical mobility. Microbial biosensors have been combined with various newly emerging micro/nanotechnologies and utilised to a wide range of detection applications to overcome such restrictions. This review article examines micro/nanotechnologies that have been combined with microbial biosensors and highlights current developments and applications that have resulted from such innovative integration. Future perspectives on the integration of micro/nanotechnologies with microbial biosensors will be explored, as will the essential advances and enhancements.
Microorganisms are of great importance to environment and essential to all life forms, and are primary source of nutrients and act as leading recycler in environment. Microorganisms are present in exceedingly large sphere of environment and develop from abyssal zone to stratosphere (at heights up to 60 km) and in a wide range of temperatures varying from arctic ice to boiling volcanoes.
