The systematic classification of the genus Pleurotus has been much debated due to changes in the names of the species, however, biochemical, chemical and molecular tools support the classification by morphological characteristics. The main species are Pleurotus ostreatus (Jacq.:Fr) Kummer, Pleurotus florida Eger, Pleurotus eryngii (DC.:Fr)

Quel, Pleurotus sajor-caju Fr.:Fr., Pleurotus cystidiosus O.K.Mill (P. abalonus Han, Chen & Cheng), Pleurotus cornucopiae (Paulet) Rolland, Pleurotus djamor (Rumph. ex Fr.) and Pleurotus pulmonarius (Fr.) Quél. In general, there is great interest in the study and production of these fungi since the nutritional value of their fruiting bodies (in particular for the protein content, including essential amino acids, fibre, vitamins and minerals) is widely documented. Furthermore, these fungi could be considered as a nutraceutical food since it has been reported that they contain biomolecules which help in certain diseases, including acquired immune deficiency syndrome (AIDS), autoimmune diseases (e.g. rheumatoid arthritis) and hypercholesterolemia, and which have anti-hypertension and antitumour activity. Molecules of major importance are statins, lectins, antioxidant compounds, glucans and enzymes. The latter are of industrial importance: (i) the hydrolases of Pleurotus can be used in several industries, including the food sector; and (ii) the phenoloxidases have been extensively studied as they could be used in the bioremediation processes to degrade xenobiotic compounds such as derivatives of paper processing, wastewater treatment and pesticides. The genus Pleurotus is of great importance as a food and as a source of many bioactive compounds.

26 Fame

Mike Roos Quarry Books ePub

For the third time in nine days, bedlam reigned on Elmer Loehr’s fine Huntingburg hardwood. But it’s doubtful he suffered as much as did the Washington Hatchets, whose turn it was to stand by in crushed disbelief and watch as the Spuds heaped themselves on each other in mad celebration and the Ireland cheering section rushed forth again in a frenzy of uncontrollable street shoes to share a greater joy than any of them had ever thought possible. So what if they left a few scuffmarks on the floor? Any blemishes would surely be waxed out in time for the next season and the next group of celebrants.

For the most part, this celebration duplicated the ecstasy of the week before. Not that any of the revelers had specific ideas about the thing to do or really knew precisely what it was they were doing. It was all supremely spontaneous and monumentally mindless: unrestrained impromptu dancing, uncontainable laughter, tribal chanting, and, of course, the ritual hoisting of heroes atop the shoulders of strong young men. Pete Gill wisely found ways to avoid being hoisted, if for no other reason than to spare the seams of his pants. As the god of the moment, the maker of the miraculous shot, Pat Schitter naturally received more adoration than anyone, although he and everyone else knew that each of the five starting (and finishing) Spuds had made his own very important and quite essential contributions to the victorious effort.

9. Leading a NewSmart Organization

Hess, Edward D.; Ludwig, Katherine Berrett-Koehler Publishers ePub

In this chapter we turn our focus to the organization of the future and to creating the kind of work environment most conducive to humans excelling at the four SMA Skills and reaching their highest potential in the SMA. To do that requires an organizational system in which the structure, culture, human resource policies, leadership behaviors, measurements, rewards, and processes are aligned seamlessly in a self-reinforcing manner that embraces and encourages the NewSmart + Humility mental model and NewSmart Behaviors. We don’t know what the future will be like. However, based on our work, we believe that the following is more likely than not:

1. The organization of the future will likely look a lot different than the organization of today because of converging forces of change: technology, demographic shifts, the loci of economic growth in the world, and ever-increasing transparency, connectivity, change, and uncertainty.

2. In most cases, the organization of the future will likely be staffed by some combination of smart robots, smart thinking machines, and humans, with humans doing those tasks that complement technology or that technology can’t do well.

13. Greater Goal Coaching

Jennings, Ken Berrett-Koehler Publishers ePub

Alexs assistant overheard the whole exchange with Dr. Stan and stepped back into Alexs office to comment, Isnt that great? I do wish your dad was here to see that. By the way, Quinn is here to see you.

As Alex waited for Quinn to come in, he looked around his office. Posted on all four walls were enlarged pictures of the whiteboards from the warehouse sessions with the goals and initiative descriptions. Almost metaphorically they covered up many pieces of Alexs past accomplishments. He smiled to himself as he realized how much he appreciated the current office artwork. Quinn joined him in his office and also noticed the new dcor. What do you think of whats happened, Alex?

Amazing, Alex answered. I just had Dr. Stan in here giving me some great stories. Just amazing—I never knew there were so many great ideas and such great energy for our Greater Goal. I guess when you constantly just tell people what to do, you never really tap into the greatness that lies within them. His voice betrayed some sadness.

Action: Raise the Bar

Jennings, Ken; Stahl-Wert, John Berrett-Koehler Publishers ePub

“BioWorks is on everyone’s list of hot companies,” Ali began. I started a fresh section in my journal. “It’s an innovative, high-science organization committed to next-generation sustainable technologies. Over the years, it has focused on agriculture and energy, especially in the area of biofuels. The company’s work with biomass conversion points the way to energy sources that are totally renewable, carbon neutral, and biodegradable.”

Puzzled, I glanced over at Ali. I had no knowledge of this field and hadn’t understood a word he had just said.

“No greenhouse gases,” Ali explained. “No global warming. And no dependence on foreign oil. It’s big!” he added with a grin, making sure I saw the size of the frontier BioWorks was exploring.

“What you’re going to find really interesting, though, is the competitive edge BioWorks has gained in this new global market through its commitment to Serving Leadership.”

Arriving at a series of low-slung buildings, we were greeted at the door by Stephen Cray, one of the CEOs I had met the day before.
