Pioneers of microbiology and the Nobel prize
We are swamped with information and each day seems to bring new discoveries that must be considered. Never before in the history of science have so many scientists been as active as today. It has become a major problem for the expert just to keep up with the literature in his or her own field of research. Why, then, should experts and their poor students worry about the pioneers of microbiology, those half-forgotten scientists who a century ago devoted their lives to a new science that was on its way to revolutionizing medicine?
With so many new facts and problems screaming for our attention, it is easy to lose sight of the long road that we have travelled in order to get to the point where we are now. Tracing the path of those who have gone before us will help us to see our own scientific goals and efforts in a more revealing perspective.
The great figures who are at the center of interest in this book - Robert Koch, Emil von Behring, Paul Ehrlich and Elie Metchnikoff - were far from uncontroversial during their lifetimes. It is interesting to see how they were judged by their peers at the Karolinska Institutet when they were considered for the Nobel Prize.
Pioneers of Microbiology and the Nobel Prize has been written in such a way that it can be enjoyed even without an extensive knowledge of microbiology and medicine. In fact, a considerable part of the book portrays the state of medicine during the middle of the 19th century, when bacteriology can be said to have made its debut on the medical scene.

Duel without end : mankind's battle with microbes
From the bubonic plague to theoretical pathogens on other worlds, a sweeping look at the past, present, and future of mass infections and how we battle them. In this panoramic and up-to-date account, we learn how the Black Death, smallpox, the 1918 influenza pandemic, and other great epidemics have not only led to enormous suffering and mass death but have also contributed to the fall of empires and changed the course of history. We also discover how new infectious diseases such as HIV/AIDS and COVID-19 emerge and how we wage war against them.

New sustainable alternatives to reduce the production costs for surfactin 50 years after the discovery
In 1968, Arima et al. discovered the heptapeptide, known as surfactin, which belongs to a family of lipopeptides. Known for its ability to reduce surface tension, it also has biological activities such as antimicrobial and antiviral. Its non-ribosomal synthesis mechanism was later discovered (1991). Lipopeptides represent an important class of surfactants, which can be applied in many industrial sectors such as food, pharmaceutical, agrochemicals, detergents, and cleaning products. Currently, 75% of the surfactants used in the various industrial sectors are from the petrochemical industry. Nevertheless, there are global current demands (green chemistry concept) to replace the petrochemical products with environmentally friendly products, such as surfactants by biosurfactants. The production biosurfactants still are costly. Thus, an alternative to reduce the production costs is using agro-industrial waste as a culture medium associated with an efficient and scalable purification process. This review puts a light on the agro-industrial residues used to produce surfactin and the techniques used for its recovery.

The song of the cell : an exploration of medicine and the new human
\"The discovery of cells--and the reframing of the human body as a cellular ecosystem--announced the birth of a new kind of medicine based on the therapeutic manipulations of cells. A hip fracture, a cardiac arrest, Alzheimer's, dementia, AIDS, pneumonia, lung cancer, kidney failure, arthritis, COVID--all could be viewed as the results of cells, or systems of cells, functioning abnormally. And all could be perceived as loci of cellular therapies. In The Song of the Cell, Mukherjee tells the story of how scientists discovered cells, began to understand them, and are now using that knowledge to create new treatments and new humans\"--Dust jacket flap.

Microbial production of hyaluronic acid: current state, challenges, and perspectives
Hyaluronic acid (HA) is a natural and linear polymer composed of repeating disaccharide units of β-1, 3-
N
-acetyl glucosamine and β-1, 4-glucuronic acid with a molecular weight up to 6 million Daltons. With excellent viscoelasticity, high moisture retention capacity, and high biocompatibility, HA finds a wide-range of applications in medicine, cosmetics, and nutraceuticals.
Traditionally HA was extracted from rooster combs, and now it is mainly produced via streptococcal fermentation. Recently the production of HA via recombinant systems has received increasing interest due to the avoidance of potential toxins. This work summarizes the research history and current commercial market of HA, and then deeply analyzes the current state of microbial production of HA by
Streptococcus zooepidemicus
and recombinant systems, and finally discusses the challenges facing microbial HA production and proposes several research outlines to meet the challenges.

All in a drop : how Antony van Leeuwenhoek discovered an invisible world
\"For fans of the 'Who Was' series, this lively, accessible, and full-color chapter book biography shows how a self-taught scientist was the first to observe the microbial life in and around us. By building his own microscope, Antony van Leeuwenhoek advanced humanity's understanding of our oft-invisible world around us\"-- Provided by publisher.

One hundred years of clostridial butanol fermentation
Butanol has been widely used as an important industrial solvent and feedstock for chemical production. Also, its superior fuel properties compared with ethanol make butanol a good substitute for gasoline. Butanol can be efficiently produced by the genus Clostridium through the acetone–butanol–ethanol (ABE) fermentation, one of the oldest industrial fermentation processes. Butanol production via industrial fermentation has recently gained renewed interests as a potential solution to increasing pressure of climate change and environmental problems by moving away from fossil fuel consumption and moving toward renewable raw materials. Great advances over the last 100 years are now reviving interest in bio-based butanol production. However, several challenges to industrial production of butanol still need to be overcome, such as overall cost competitiveness and development of higher performance strains with greater butanol tolerance. This minireview revisits the past 100 years of remarkable achievements made in fermentation technologies, product recovery processes, and strain development in clostridial butanol fermentation through overcoming major technical hurdles.

Ochratoxin A: 50 Years of Research
Since ochratoxin A (OTA) was discovered, it has been ubiquitous as a natural contaminant of moldy food and feed. The multiple toxic effects of OTA are a real threat for human beings and animal health. For example, OTA can cause porcine nephropathy but can also damage poultries. Humans exposed to OTA can develop (notably by inhalation in the development of acute renal failure within 24 h) a range of chronic disorders such as upper urothelial carcinoma. OTA plays the main role in the pathogenesis of some renal diseases including Balkan endemic nephropathy, kidney tumors occurring in certain endemic regions of the Balkan Peninsula, and chronic interstitial nephropathy occurring in Northern African countries and likely in other parts of the world. OTA leads to DNA adduct formation, which is known for its genotoxicity and carcinogenicity. The present article discusses how renal carcinogenicity and nephrotoxicity cause both oxidative stress and direct genotoxicity. Careful analyses of the data show that OTA carcinogenic effects are due to combined direct and indirect mechanisms (e.g., genotoxicity, oxidative stress, epigenetic factors). Altogether this provides strong evidence that OTA carcinogenicity can also occur in humans.
