A spore print is made by placing the spore-producing surface flat on a sheet of dark and white paper or on a sheet of clear, stiff plastic, which facilitates moving the spore print to a darker or lighter surface for improved contrast; for example, it is easier to determine whether the spore print is pure white or, rather, very slightly pigmented. The mushroom is left for several hours, often overnight, in this manner. Some guides advise using a moisture-resistant enclosure, like a glass or jar, to contain the mushroom during printing. If the mushroom is to be preserved, a small hole can be made in the spore print paper rather than cutting the stipe.[2] When the mushroom is removed, the colour of the spores should be visible. Mycologists often use glass slides, which allow for quick examination of spores under a microscope. A mushroom cannot be identified from its spore print alone; the spore print is only one characteristic used in making a taxonomic determination. Spore prints are usually white ...
In fungi, both asexual and sexual spores or sporangiospores of many fungal species are actively dispersed by forcible ejection from their reproductive structures. This ejection ensures exit of the spores from the reproductive structures as well as travelling through the air over long distances. Many fungi thereby possess specialized mechanical and physiological mechanisms as well as spore-surface structures, such as hydrophobins, for spore ejection. These mechanisms include, for example, forcible discharge of ascospores enabled by the structure of the ascus and accumulation of osmolytes in the fluids of the ascus that lead to explosive discharge of the ascospores into the air.[7]. The forcible discharge of single spores termed ballistospores involves formation of a small drop of water (Bullers drop), which upon contact with the spore leads to its projectile release with an initial acceleration of more than 10,000 g.[8] Other fungi rely on alternative mechanisms for spore release, such as ...
The use of spores as probiotics is highly important as spores are designed to survive through the gastric system and colonize well to produce the needed effects. Additionally, spores make a potent impact in the gut since the spore population in the gut is low enough that the 4 billion spores added each day through MegaSporeBiotic will make a potent impact on the sensory systems in the gastrointestinal tract to create beneficial effects. Spores are also important to police and defend the gut from unwanted microbes and to support the growth of the natural species found in each individual. A mega dose, spore culture/consortium formula with broad-spectrum activity, has only been available as a pharmaceutical drug, until now MegaSporeBiotic is the first offered as a dietary supplement.. A culmination of published research shows that spores, like those found in MegaSporeBiotic, when used as probiotics could confer the following beneficial effects:. ...
Swarm robotics is a new approach to the coordination of multirobot systems which consist of large numbers of mostly simple physical robots. It is supposed that a desired collective behavior emerges from the interactions between the robots and interactions of robots with the environment. This approach emerged on the field of artificial swarm intelligence, as well as the biological studies of insects, ants and other fields in nature, where swarm behaviour occurs. ...

Nanoswarms and Microswarms: Can you escape from swarms? What if you stumble across a swarm of Disassemblers? Most morphs can easily outrun swarms. So if someone tried to run away, would they be safe or would the swarm be carried with them?. Saboteur Nanoswarm: I think this is broken. Every 5 action turns, there is a 50% chance it inflicts a wound (and equivalent damage). The target will be incapacitated once 5 wounds are inflicted.. The odds of a Case, a Reaper, or something bigger being taken down by this swarm is the same. I dont think this is right. I think bigger, tougher shells should be harder to disable. Shells with more DUR and armor.. It also skips over armor too quickly. What if the shell was wearing a vacsuit or something else that can keep the swarm out? I think it would have to disable the suit first before it can affect the shell inside.. What about Swarmaniods? There are *a lot* of moving parts to disable in that kind of shell. ...

Bacteria are one of the premier biological forces that, in combination with chemical and physical forces, drive metal availability in the environment. Bacterial spores, when found in the environment, are often considered to be dormant and metabolically inactive, in a resting state waiting for favorable conditions for them to germinate. However, this is a highly oversimplified view of spores in the environment. The surface of bacterial spores represents a potential site for chemical reactions to occur. Additionally, proteins in the outer layers (spore coats or exosporium) may also have more specific catalytic activity. As a consequence, bacterial spores can play a role in geochemical processes and may indeed find uses in various biotechnological applications. The aim of this review is to introduce the role of bacteria and bacterial spores in biogeochemical cycles and their potential use as toxic metal bioremediation agents.
Methods for enhancing destruction and killing of bacterial spores via phagocytosis, where phagocytosis of bacterial spores is enhanced by using a glycoconjugate. In one embodiment, the method includes the steps of modifying a surface of a bacterial spore to increase adherence to a phagocyte; and ingesting the adherence-increased spore with the phagocyte, thereby destructing and killing the spore by blocking spore-induced phagocyte cell death, while increasing phagocyte activation level and production of antimicrobial and cytocidal agents such as NO and inflammatory cytokines. The adherence of spore to a phagocyte is increased after the surface thereof is coated with a glycoconjugate to form a glycoconjugate-coated spores. The glycoconjugate-coated spores also increase ingestion of the spores by phagocytes and facilitate phagosome-lysosome fusion, which in turn results in destruction and killing of bacterial spores via phagocytosis. The method enhances
Terpenoids, also known as isoprenoids, are a large class of natural products consisting of isoprene (C5) units. There are two biosynthetic pathways, the mevalonate pathway [MD:M00095] and the non-mevalonate pathway or the MEP/DOXP pathway [MD:M00096], for the terpenoid building blocks: isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). The action of prenyltransferases then generates higher-order building blocks: geranyl diphosphate (GPP), farsenyl diphosphate (FPP), and geranylgeranyl diphosphate (GGPP), which are the precursors of monoterpenoids (C10), sesquiterpenoids (C15), and diterpenoids (C20), respectively. Condensation of these building blocks gives rise to the precursors of sterols (C30) and carotenoids (C40). The MEP/DOXP pathway is absent in higher animals and fungi, but in green plants the MEP/DOXP and mevalonate pathways co-exist in separate cellular compartments. The MEP/DOXP pathway, operating in the plastids, is responsible for the formation of essential oil ...
Rapid isolation and identification of spores from various environmental samples is necessitated because anthrax spores can be used as biological weapons. The hydrophobic nature of spores may allow for their rapid concentration and partial purification from contaminating materials. In this study, spores from four taxonomic groups of Bacillaceae were isolated, purified and characterized for hydrophobicity by hexadecane partitioning, surface morphology by scanning electron microscopy, and steady-state fluorescence by spectroscopy. The morphology of spores was similar within taxonomic groups and dissimilar between groups. Spore hydrophobicity ranged from 0.3% to 65% and all spores had fluorescence emission peaks at 335 nm and 450 nm. The excitation maxima for the peak at 450 nm were shifted to higher wavelengths for the least hydrophobic spores. Regression analysis demonstrated a correlation between the taxonomic identity, as established by fatty acid analyses, and hydrophobicity. Hydrophobicity can
In angiosperms, during flower development the anther is composed of a mass of cells that appear undifferentiated, except for a partially differentiated dermis. As the flower develops, four groups of sporogenous cells form with in the anther, the fertile sporogenous cells are surrounded by layers of sterile cells that grow into the wall of the pollen sac, some of the cells grow into nutritive cells that supply nutrition for the microspores that form by meiotic division from the sporogenous cells. Four haploid microspores are produced from each diploid sporogenous cell called a microsporocyte, after meiotic division. After the formation of the four microspores, which are contained by callose walls, the development of the pollen grain walls begins. The callose wall is broken down by an enzyme called callase and the freed pollen grains grow in size and develop their characteristic shape and form a resistant outer wall called the exine and an inner wall called the intine. The exine is what is ...

Bacterial spore formers have been the focus of intense study for almost half a century. The most heavily studied of these is Bacillus subtilis, an internationally recognized model organism, whose physiology, biochemistry and genetics have been studied for many years. Under nutrient rich conditions, B. subtilis grows and multiplies by a process of cell expansion followed by division at mid-cell to generate identical daughter cells; however, B. subtilis also has the ability to form spores, dormant cells which are resistant to many of the chemical and physical challenges that normally kill bacteria. Although many of the basic aspects of this process are now well understood, bacterial sporulation still remains a highly attractive model for studying various cell processes at a molecular level. There are several reasons for this interest. First, some of the more complex sporulation steps are not fully understood or are only described using controversial models. Second, the extensive attention lavished on

Parasite spores. Coloured scanning electron micrograph (SEM) of microsporidia (Tubulinosema ratisbonensis) spores cultured on human lung fibroblast cells (brown). Microsporidia are single-celled parasites. T. ratisbonenesis is a parasite of the fruit fly (Drosophila melanogaster), but may also be able to infect humans with weakened immune systems. The spores are the infective phase of the life cycle. They are excreted by the host and enter the gut of a new host. The spores contents, the sporoplasm, are injected into the hosts cells via the polar tubule (two seen). Once in the cell the organism divides many times with the resultant organisms producing more spores. Magnification: x5100 at 10 centimetres wide. - Stock Image Z115/0075
Instead of tight, focused columns that concentrate the ants efforts at a single point at the raid front, E. burchelliis raids are messy, diffuse affairs. Foragers spread out in a swarm, casting a vicious stinging, biting net for animals too slow to escape. The strategy isnt great for capturing concentrated food sources like another ant colony, but it works well for a generalists lunch.. Raids set out in the morning with a swarm front near the overnight bivuoac. As the day progresses, the swarm moves through the forest for a distance about that of a football field. The back end of the swarm organizes into a series of converging trails to funnel captured prey back to the bivouac, so that by mid-day the swarm from above looks rather like the figure at left. Last nights video featured one such trail. By nightfall the ants are back in the bivuoac, where, depending on the development of their larvae, they either regroup to march to a new bivouac site by morning, or they stay put and launch a new ...

Now, sometimes we are lucky and can "hive the swarm" if the queen lands in a convenient and easy to reach location (not on a branch 200 feet in the air). But what really sucks about swarms, especially for queen breeders, is when their prized queen, (the one theyve been collecting data on for the past few years; the one they are about to graft from to produce more queens), flies away - or as we seasoned beekeepers like to say, she "hits the trees." One of the largest swarms I ever saw was in the top of an old pine tree. It broke my heart because in the middle of that massive, unreachable swarm was one of my favorite queens that I was only days away from grafting from. If only I had a bucket truck, she would have been back inside a comfy hive. Instead, she flew away several days later - never to be seen again. Over the years, our bee lab receives numerous calls during the Spring months about swarms - from frustrated beekeepers to nervous public folk who are afraid to go outside due to the massive ...
We are particularly interested in understanding the molecular mechanisms of spore germination, which dormant spores undergo when stimulated to return to the vegetative state. We are also interested in the composition and assembly of the spore coat and exosporium, and aim to define the structures and functions of the various proteins that form this primary protective barrier.. We use a range of approaches to gain insight to spore biology at the molecular level, including genetic, biochemical, crystallographic and advanced imaging techniques.. Overall, our objective is to consider fundamental insights to spore structure and physiology in the context of public health, food safety, counter-terrorism and environmental decontamination, and to determine how such information might then be applied to improve current capabilities in these sectors.. Enquiries concerning post-graduate research opportunities, industrial collaborations, or general information concerning the groups activities, should be ...
TY - GEN. T1 - Effect of ovalbumin and anti-foam B on the survivability of spore forming bacteria collected in a Wetted Wall Cyclone. AU - Kassab, Asmaa S.. AU - King, Maria D.. AU - Guo, Bing. AU - McFarland, Andrew R.. PY - 2011. Y1 - 2011. N2 - The effect of different collection fluids in maintaining the survivability, defined as the culturability in the archived sample divided by the culturability in the as-collected sample, were experimentally determined for Bacillus globigii (BG). The spores were collected using a 100 L/min Wetted Wall Cyclone (WWC) and archived for five days at 25°C and 4°C. Aqueous solutions of 0.01% Tween20 and 30% Ethylene glycol (EG), with or without 0.5% ovalbumin (OA), were used as collection fluids with 0.2% Antifoam B (A-F). The spores were more stable in EG and at 4°C, very likely due to the surfactant effect of the Tween20, which would remove the spore coat and initiate germination. Adding OA significantly increased the survivability, especially at RT while ...
Endospore Stain The endospore stain is a differential stain used to visualize bacterial endospores. Endospores are formed by a few genera of bacteria, such as Bacillus . By forming spores, bacteria can survive in hostile conditions. Spores are resistant to heat, dessication, chemicals, and radiation. Bacteria can form endospores in approximately 6 to 8 hours after being exposed to adverse conditions. The normally-growing cell that forms the endospore is called a vegetative cell. Spores are metabolically inactive and dehydrated. They can remain viable for thousands of years. When spores are exposed to favorable conditions, they can germinate into a vegetative cell within 90 minutes. Endospores can form within different areas of the vegetative cell. They can be central, subterminal, or terminal. Central endospores are located within the middle of the vegetative cell. Terminal endospores are located at the end of the vegetative cell. Subterminal endospores are located between the middle and the end ...

Yo netters, Ive been taught and have taught that mosses and liverworts are homosporous, however, many texts and even lab books show two kinds of gametophytes being produced from two different spores. Does this mean that although the spores look alike they are still different? Is this homospory or heterospory? What is going on here? Are there two kinds of homospory where one spore produces one gametophyte with both archegonia and antheridia and another where there are two kinds of gametophytes? I know the plants couldnt care less!! Can anyone answer this?

A longstanding challenge in developmental biology is to understand how organisms construct large structures that ultimately help define how that organism looks. We are approaching this problem by examining the morphogenesis of a simple organism, a bacterial spore, and are trying to understand how it achieves its characteristic morphology. Spores are dormant cell types that are encased in a thick protein shell, termed the "coat". Spores are highly resistant to environmental insults, and this resistance is due, in part, to the protective properties of the coat. Assembly of the basement layer of the coat depends on a tiny protein, called SpoVM, which anchors the coat onto the surface of the developing spore. We have discovered that SpoVM localizes properly by preferentially embedding in convex, or positively curved, membranes, such as those found on the surface of the spore. SpoVM then recruits a novel cytoskeletal protein, called SpoIVA, which polymerizes by hydrolyzing ATP to form a stable ...
You can see, in Figure 2, how a swarm regulates its collective temperature at different ambient air temperatures; on the left side it is only 5oC (40°F), and the bees are having to work hard to actively maintain the temperature between the core (35oC) and the mantle (19oC). A hot day of 30oC (86oF) is illustrated on the right, and bees in the mantle are mostly at rest with some active bees, most likely to be scouts. The channels between bees allows air to circulate by convection helping keep the temperature in the middle uniformly 35oC (95oF), whilst the mantle is 31oC (88oF).. But how does all this relate to swarm takeoff? Well, typically a swarm of about 10,000 honey bees hangs in a beard-like cluster from a solid object, often a tree, whilst the 300 to 500 scout bees go and choose a new home. They may hang for a few hours, or a few days, until a quorum of scouts has built up at one of the sites, which marks the end of the scouts decision-making process. Then its time for all the bees in ...

To study and characterise the ionospheric plasma irregularities at all latitudes, one can employ in-situ measurements by satellites in polar orbits, such as the European Space Agencys Swarm mission. Based on the Swarm data, we have developed the Ionospheric Plasma IRregularities (IPIR) product for a global characterisation of ionospheric irregularities along the satellite track at all latitudes. This new Level-2 data product combines complementary datasets from the Swarm satellites: the electron density from the electric field instrument, the GPS data from the onboard GPS receiver, and the magnetic field data from the onboard magnetometers. This can be used as a new tool for global studies of ionospheric irregularities and turbulence ...
Blizzard Entertainment released several screenshots of the Evolution Chamber UI which allows you to upgrade your units in between each mission. Kaldir and Char scenarios and critters. Some of the mission objectives are shown..
