Sulfolobus acidocaldarius is an Archaean extremophile. This strictly aerobic prokaryote is found in the searing temperatures of sulfur-rich geothermal hot acid springs, geysers, and deep ocean vents. While primarily an aquatic organism, S. acidocaldarius can also be found in hot acidic soils. Optimal conditions for S. acidocaldarius included a temperature of 80°C and a hydronium ion concentration, pH, of 2; making them acidophiles (acid loving) and thermophiles (heat loving). (Wikipedia #2). As…

The book, The Forest Unseen, A Year’s Watch in Nature by David George Haskell is his experiences in his year-long journey in a mandala within the Tennessee forests. He describes many different types of wildlife he observes during his time in the forest. The purpose of the author writing this novel is to show how the life in the mandala relies on each other for survival. All the wildlife in the mandala depend on each other to survive. The first example of relationships in the forest is on page 2…

Austrian pine (Pinus nigra) tolerates well both hot and colder temperatures, also drought. This is due to the dense horizontal root system that goes deeper than most Pinus species'. (Magyar 1960) As a tree that feels itself home mostly in continental mountain ranges and the Mediterranean climate, its home range stretches from Iberia through the Alps to the Taurus mountains in Asia Minor. It is medium to fast growing with a pyramidal crown. It is mostly resistant to breakage. (Gilman-Watson,…

How Can I Tell If There Is Mold In My Home? Mold grows from spores, which are found naturally in the air and cannot be seen by the naked eye. Mold spores act like seeds causing mold to grow under the right conditions. Mold itself is usually easy to detect. While testing is sometimes used to determine the presence of mold, it is often not necessary, as usually a quick investigation with your eyes and nose can tell you if mold is present. Some common signs of mold growth include: • Visible mold…

raised beds, good housekeeping on weed control, and also on all equipment used in the garden. Club root is a fungal infection there are no chemical treatment’s the infection can attack when the soil is warm and moist mid-summer to late autumn. The spores can contaminate the soil for up to 20…

The moss Physcomitrella patens is an attractive model system for plant biology and functional genome analysis.(1-7) It shares many biological features with higher plants (vascular plants) but has the unique advantage of an efficient homologous recombination system for its nuclear DNA.(2,3) This allows precise genetic manipulations and targeted knockouts to study gene function, an approach that due to the very low frequency of targeted recombination events is not routinely possible in any higher…

Is it safe to remove the mold from your bread and eat it? We have all done this even though we seldom want to tell it. You check the bread drawer, you take two slices of bread for a sandwich and there you find it, on the surface of your bread, a small circle of mold. The dinner killer! Still who cares, it is just a small bit, I will remove it and eat the good part, what is the worst that could happen? I'm not going to let a small mold spot waste a whole slice of bread. So, if you’ve done this,…

to prevent introducing micro-organisms in otherwise sterile specimens. This can be achieved by employing appropriate techniques of sterilisation or disinfection. Sterilization It is the removal or destruction of all micro-organisms including spores from a material. Sterilisation procedures involve either physical or chemical methods.…

The lifecycle of the septoria brown spot fungus begins when it overwinters in crop residue, infected seed, leaf and stem debris as minute brown fruiting bodies (pycnidia). The microscopic spores produced on living tissues or dead plants are released during wet weather. Wind and rainfall disperses the spores onto healthy plants, and infection begins. Favorable…
