Microbiology Of Life Quotes

Twenty years after Waksman’s death, the American Society for Microbiology made a somewhat belated attempt at amends by inviting Schatz to address the society on the occasion of the fiftieth anniversary of streptomycin’s discovery. In recognition of his achievements, and presumably without giving the matter a lot of thought, it bestowed on him its highest award: the Selman A. Waksman medal. Life sometimes really is very unfair.

I take it you’ve never seen a Flasher at work before?” Elwin asked her. “No,” Tarina admitted. “But I’ve wanted to, ever since I first heard the legends.” “Legends,” Bo scoffed. “You’re looking at a party trick—nothing more. You want to see something legendary, you should visit our microbiology labs.” “Yes, nothing’s more exciting than bacteria,” Elwin muttered. “And just so we’re clear—my ‘party trick’ saved your princess’s life.

The more formidable the contradiction between inexhaustible life-joy and inevitable fate, the greater the longing which reveals itself in the kingdom of poetry and in the self-created world of dreams hopes to banish the dark power of reality. The gods enjoy eternal youth, and the search for the means of securing it was one of the occupations of the heroes of mythology and the sages, as it was of real adventurers in the middle ages and more recent times. . . . But the fountain of youth has not been found, and can not be found if it is sought in any particular spot on the earth. Yet it is no fable, no dream-picture; it requires no adept to find it: it streams forth inexhaustible in all living nature.

Among the most virulent of all such cultural parasite-equivalents is the religion-based denial of organic evolution. About one-half of Americans (46 percent in 2013, up from 44 percent in 1980), most of whom are evangelical Christians, together with a comparable fraction of Muslims worldwide, believe that no such process has ever occurred. As Creationists, they insist that God created humankind and the rest of life in one to several magical mega-strokes. Their minds are closed to the overwhelming mass of factual demonstrations of evolution, which is increasingly interlocked across every level of biological organization from molecules to ecosystem and the geography of biodiversity. They ignore, or more precisely they call it virtue to remain ignorant of, ongoing evolution observed in the field and even traced to the genes involved. Also looked past are new species created in the laboratory. To Creationists, evolution is at best just an unproven theory. To a few, it is an idea invented by Satan and transmitted through Darwin and later scientists in order to mislead humanity. When I was a small boy attending an evangelical church in Florida, I was taught that the secular agents of Satan are extremely bright and determined, but liars all, man and woman, and so no matter what I heard I must stick my fingers in my ears and hold fast to the true faith. We are all free in a democracy to believe whatever we wish, so why call any opinion such as Creationism a virulent cultural parasite-equivalent? Because it represents a triumph of blind religious faith over carefully tested fact. It is not a conception of reality forged by evidence and logical judgment. Instead, it is part of the price of admission to a religious tribe. Faith is the evidence given of a person’s submission to a particular god, and even then not to the deity directly but to other humans who claim to represent the god. The cost to society as a whole of the bowed head has been enormous. Evolution is a fundamental process of the Universe, not just in living organisms but everywhere, at every level. Its analysis is vital to biology, including medicine, microbiology, and agronomy. Furthermore psychology, anthropology, and even the history of religion itself make no sense without evolution as the key component followed through the passage of time. The explicit denial of evolution presented as a part of a “creation science” is an outright falsehood, the adult equivalent of plugging one’s ears, and a deficit to any society that chooses to acquiesce in this manner to a fundamentalist faith.

Jack coughed slightly and offered his hand. “Hi, uh. I’m Jack.” Kim took it. “Jack what?” “Huh?” “Your last name, silly.” “Jackson.” She blinked at him. “Your name is Jack Jackson?” He blushed. “No, uh, my first name’s Rhett, but I hate it, so…” He gestured to the chair and she sat. Her dress rode up several inches, exposing pleasing long lines of creamy skin. “Well, Jack, what’s your field of study?” “Biological Engineering, Genetics, and Microbiology. Post-doc. I’m working on a research project at the institute.” “Really? Oh, uh, my apple martini’s getting a little low.” “I’ve got that, one second.” He scurried to the bar and bought her a fresh one. She sipped and managed to make it look not only seductive but graceful as well. “What do you want to do after you’re done with the project?” Kim continued. “Depends on what I find.” She sent him a simmering smile. “What are you looking for?” Immediately, Jack’s eyes lit up and his posture straightened. “I started the project with the intention of learning how to increase the reproduction of certain endangered species. I had interest in the idea of cloning, but it proved too difficult based on the research I compiled, so I went into animal genetics and cellular biology. It turns out the animals with the best potential to combine genes were reptiles because their ability to lay eggs was a smoother transition into combining the cells to create a new species, or one with a similar ancestry that could hopefully lead to rebuilding extinct animals via surrogate birth or in-vitro fertilization. We’re on the edge of breaking that code, and if we do, it would mean that we could engineer all kinds of life and reverse what damage we’ve done to the planet’s ecosystem.” Kim stared. “Right. Would you excuse me for a second?” She wiggled off back to her pack of friends by the bar. Judging by the sniggering and the disgusted glances he was getting, she wasn’t coming back. Jack sighed and finished off his beer, massaging his forehead. “Yes, brilliant move. You blinded her with science. Genius, Jack.” He ordered a second one and finished it before he felt smallish hands on his shoulders and a pair of soft lips on his cheek. He turned to find Kamala had returned, her smile unnaturally bright in the black lights glowing over the room. “So…how did it go with Kim?” He shot her a flat look. “You notice the chair is empty.” Kamala groaned. “You talked about the research project, didn’t you?” “No!” She glared at him. “…maybe…” “You’re so useless, Jack.” She paused and then tousled his hair a bit. “Cheer up. The night’s still young. I’m not giving up on you.” He smiled in spite of himself. “Yet.” Her brown eyes flashed. “Never.

In the 1940s and 1950s, the study of natural history--an intimate science predicated on the time-consuming collection and naming of life-forms--gave way to microbiology, theoretical and commercial. Much the same thing happened to the conservation movement, which shifted from local preservationists with soil on their shoes to environmental lawyers in Washington, D.C.

Scientists working on the origin of life deserve a lot of credit; they have attacked the problem by experiment and calculation, as science should. And although the experiments have not turned out as many hoped, through their efforts we now have a clear idea of the staggering difficulties that would face an origin of life by natural chemical processes. In private many scientists admit that science has no explanation for the beginning of life.

It’s the start of a new era, when people are finally ready to embrace the microbial world. When I walked through San Diego Zoo with Rob Knight at the start of this book, I was struck by how different everything seemed with microbes in mind. Every visitor, keeper, and animal looked like a world on legs – a mobile ecosystem that interacted with others, largely oblivious to their inner multitudes. When I drive through Chicago with Jack Gilbert, I experience the same dizzying shift in perspective. I see the city’s microbial underbelly – the rich seam of life that coats it, and moves through it on gusts of wind and currents of water and mobile bags of flesh. I see friends shaking hands, saying’ “how do you do”, and exchanging living organisms. I see people walking down the street, ejecting clouds of themselves in their wake. I see the decisions through which we have inadvertently shaped the microbial world around us: the choice to build with concrete versus brick, the opening of a window, and the daily schedule to which a janitor now mops the floor. And I see, in the driver’s seat, a guy who notices those rivers of microscopic life and is enthralled rather than repelled by them. He knows that microbes are mostly not to be feared or destroyed, but to be cherished, admired, and studied.

If I went to a library and lobbed a microbiology textbook out the window, I could easily concuss a passer-by. If I tore out all the pages that dealt with beneficial microbes, I could just about give someone a nasty paper cut. The narrative of disease and death still dominates our view of microbiology.

Martinus Beijerinck, a Dutchman, was amongst the first to demonstrate their planetary importance. Reclusive, brusque, and unpopular, he had no love for people, except for a few close colleagues, nor any love for medical microbiology. Disease didn't interest him. He wanted to study microbes in their natural habitats: soil, water, plant roots. In 1888, he found bacteria that pulled nitrogen out of the air and turned it into ammonia for plants to use; later, he isolated species that contributed to the movements of sulphur through the soil and atmosphere. This work stimulated a rebirth of microbiology in Beijerinck's city of Delft-where Leeuwenhoek had first laid eyes on bacteria two centuries earlier. The members of this new found Delft school, along with intellectual soulmates like the Russian Sergei Winogradsky, called themselves microbial ecologists. They revealed that microbes were not just threats to humanity but critical components of the world.

Without this [Soil Food Web system of bacteria, fungi etc], most important nutrients would drain from soil. Instead, they are retained in the bodies of soil life. Here is the gardener's truth: when you apply a chemical fertilizer, a tiny bit hits the rhizosphere, where it is absorbed, but most of it continues to drain through soil until it hits the water table. Not so with the nutrients locked up inside soil organisms, a state known as immobilization; these nutrients are eventually released as wastes, or mineralized.

Bacteria are so small they need to stick to things or they will wash away; to attach themselves, they produce a slime, the secondary result of which is that individual soil particles are bound together. [...] Fungal hyphae, too, travel through soil, sticking to them and binding them together, thread-like, into aggregates. [...] The soil food web, then, in addition to providing nutrients to roots in the rhizosphere, also helps create soil structure: the activities of its members bind soil particles together even as they provide for the passage of air and water through the soil. [...] The nets or webs fungi form around roots act as physical barriers to invasion and protect plants from pathogenic fungi and bacteria. Bacteria coat surfaces so thoroughly, there is no room for others to attach themselves. If something impacts these fungi or bacteria and their numbers drop or they disappear, the plant can easily be attacked.

Few realize that a great deal of the energy that results from photosyntheisis in the leaves is actually used by plants to produce chemicals they secrete through their roots. These secretions are known as exudates. [...] Root exudates are in the form of carbohydrates (including sugars) and proteins. Amazingly, their presence wakes up, attracts and grows specific beneficial bacteria and fungi living in the soil that subsist on these exudates and the cellular material sloughed off as the plant's root tips grow. [...] During different times of the growing season, populations of rhizosphere bacteria and fungi wax and wane, depending on the nutrient needs of the plant and the exudates it produces. [...] Plants produce exudates that attract fungi and bacteria (and, ultimately, nematodes and protozoa); their survival depends on the interplay between these microbes. It is a completely natural system, the very same one that has fueled plants since they evolved. Soil life produces the nutrients needed for plant life, and plants initiate and fuel the cycle by producing exudates.

part together. This struck me as important. But 2 percent is always alive. From a certain microbiological standpoint, trees are immortal. I think history is like this. We cannot capture much more than the trees do of what is living about history. The rest is solid cortex. It stands and is of use to the living part.

Studying microbiology is delving into the vast realm of life's tiniest yet profound influencers—the silent revolutionaries shaping our world.

Speaking of which, what counts as dysbiosis? [...] The term is great at conveying the ecological nature of disease but it has also become microbiology's version of art and pornography: hard to define, but you know it when you see it.
