Microbiology Quotes

“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.”

“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.”

“We search the stars for creators, yet they dwell in the smallest speck—breathing life into matter, programming the dance of existence.”

“Humanity shares a common ancestry with all living things on Earth. We often share especially close intimacies with the microbial world. In fact, only a small percentage of the cells in the human body are human at all. Yet, the common biology and biochemistry that unites us also makes us susceptible to contracting and transmitting infectious disease.”

“There's no such thing as good and bad bacteria or fungi. It's not good and bad. It's just whether there's too much of it or too little of it and things are out of balance, so the 'bad things' have an opportunity to prosper.”

“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.”

“Quick dinner with ... Ang [Lee] and his wife Jane who's visiting with the children for a while. We talked about her work as a microbiologist and the behaviour of the epithingalingie under the influence of cholesterol. She's fascinated by cholesterol. Says it's very beautiful: bright yellow. She says Ang is wholly uninterested. He has no idea what she does. I check this out for myself. 'What does Jane do?' I ask. 'Science,' he says vaguely.”

“Let me tell you the secret that has led me to my goal. My strength lies solely in my tenacity.”

“Science is an attempt, largely successful, to understand the world, to get a grip on things, to get hold of ourselves, to steer a safe course. Microbiology and meteorology now explain what only a few centuries ago was considered sufficient cause to burn women to death.”
