Bacteriën De Bacteria werden vroeger Eubacteria genoemd. In het algemene spraakgebruik wordt meestal geen onderscheid gemaakt tussen Bacteria ("gewone" bacteriën) en Archaea (oerbacteriën), die tezamen de groep prokaryoten vormen. In de taxonomie vormen de Bacteria echter een afzonderlijk domein. Blauwalgen of blauwwieren (cyanobacteriën) behoren tot de bacteriën, en niet - zoals de naam suggereert - bij de eukaryote algen. Algemeen[bewerken] De meeste bacteriën zijn niet schadelijk maar soms zelfs nuttig voor de gezondheid, bijvoorbeeld in onze darmen. Bouw[bewerken] Structuur van een bacterie Het inwendige van een bacterie bestaat uit cytoplasma met onder andere het DNA. Variatie[bewerken] Bacteriën kunnen op verschillende manieren van elkaar worden onderscheiden. Vorm[bewerken] A. staafvormig, B. bolvormig, C. bolvormig in clusters, D. bolvormig in paren, E. spiraalvormig, F. kommavormig Te onderscheiden zijn: kokken (bolvormige bacteriën), rond van vorm, al of niet losliggend.

Growth on Agar Perhaps this will be the year when you devote a corner of your garden to growing your own portabellas, criminis, shitakes, shaggy manes, Lepiotas, oysters, enokitakes. In this column we will give a basic outline of mushroom cultivation techniques and try to answer your questions about cultivation. Each article will briefly cover a different aspect of mushroom cultivation: I hope cultivation corner will provide stimulus and help you establish your own cultivation corner. Happy hunting and growing! I. The first phase of mushroom cultivation is the isolation of a pure culture of mycelium. PD(Y)A should be sterilized for 45 minutes at 15 pounds pressure. Potato Dextrose (Yeast) Agar (PD(Y)A): Potato Water 1 liter Dextrose 10 grams Nutritional Yeast or Yeast Extract 1-3 grams (optional) Agar- agar 20 grams Potato water is prepared by boiling a large, washed but not peeled, thinly sliced potato in water for one hour. Commonly used spore isolation techniques include: A. B.
Ulva or Sea Lettuce This is a small genus of marine and brackish water green algae. It is edible and is often called 'Sea Lettuce'. Species with hollow, one-layered thalli were formerly included in Enteromorpha, but it is widely accepted now that such species should be included in Ulva. The thallus of ulvoid species is flat and blade-like and is composed of two layers of cells. There is no differentiation into tissues; all the cells of the plant are more or less alike except for the basal cells, which are elongated to form attachment rhizoids. Each cell contains one nucleus and has a cup-shaped choroplast with a single pyrenoid. Ulva undergoes a very definite alternation of generations. Ulva can be quite a nuisance in areas that are nutrient enriched from sewage outfalls e.g. There are about 100 species Ulva currently listed on AlgaeBase which is probably a considerable underestimate; nearly 600 names have been used, as this was one of the earliest genera of algae to be described (by Carl Linnaeus).
Coffee Grinds to Mushrooms: A How to Guide | LunarHarvest Yup. I’m not pulling your leg and I’m not kidding you around; oyster mushrooms (Pleurotus ostreatus) are a species of fungus that can digest coffee grinds, including the filters that they are often discarded with, and produce reliable crops of mushrooms. I was skeptical at first but after doing what seemed to be no more than a month casually searching through online do-it-yourself blogs and investigating companies which distribute mushroom kits and spawn (such as The Mushroom Patch) I had the confidence to give it a shot. Approximately one month after mixing together the coffee grinds and mycelium together, the oyster mushrooms are well into their first flush. But why would you want to grow your own mushrooms? Plus you are not just creating any old edible material (Because edible material sounds really appetizing..) but oyster mushrooms, which are delicious and extremely good for you. Step 1. Chances are, there is a coffee shop near where you live. Now all you need is a bucket.
GSF 2013 : Project : Going Bananas!-Using Banana Peels in the Production of Bio-Plastic As A Replacement of the Traditional Petroleum Based Plastic The banana fruit’s peel was selected for this experiment because it is a waste material rich of starch-according to Songklanakarin Journal of Science and Technology, the proximate composition of a banana peel is shown below. Items Content (g/100 g dry matter) Protein: 8.6±0.1 Fat: 13.1±0.2 Starch: 12.78±0.9 Ash: 15.25±0.1 Total dietary fiber: 50.25±0.2 The banana peel is something we throw away every day, but little do we know, it has much more efficient uses. According to The Packaging Bulletin Magazine’s January issue, it is a proven fact that starch and cellulose are important raw materials used in the bioplastic industry (Packaging Bulletin, 2009). Starch consists of two different types of polymer chains, called amylose and amylopectin, made up of adjoined glucose molecules. The 9th and 10th pilot experiment I had conducted had been successful in producing plastic, but had started to decay after only 3 days.
Mushroomers ClubA Successful Story of Blue Oyster and Shiitake Mushrooms Cultivation ~ mushroomers club This is a guest post by Devon Olsen, an active member of forums (permies.com and shroomotopia.net) on permaculture and fungi cultivation. This is the story of his first attempts in cultivating Blue Oyster and Shiitake mushrooms. His story is interesting and was posted here with the intention to help some people out there in their first trials of cultivating such types of mushrooms. I guess mushrooms have always been kinda cool, but ive never really felt fascinated about them per se, but about a year ago i found a thread on permies.com about growing Oyster Mushrooms on an old phone book i think it was. Seeing those Oyster pins fascinated me, so i decided at that point to look into growing some of my own. Learn more about Oyster mushroom cultivation reading How To Grow Oyster Mushrooms on Logs or the simple plastic bag cultivation of oyster mushrooms by checking my post How To Transform Paper Into Food there you'll find links to a more detailed cultivation method of oyster mushrooms.
Zeesla Tekening uit Sowerby's English Botany Zeesla (Ulva lactuca), behoort tot de groenwieren (Chlorophyta). Ulva is Latijn voor ‘moerasplant’. Kenmerken[bewerken] In vorm en grootte variëren de vlakke, golvende thalli, die donkergroen, stevig en huidachtig zijn. Zeesla heeft een type generatiewisseling die isomorfe diplohaplont genoemd wordt, hetgeen betekent dat het een afwisseling is van een diploïde sporofyt en een haploïde gametofyt die uiterlijk niet van elkaar te onderscheiden zijn. Verspreiding[bewerken] Zeesla komt in alle zeeën voor in de overgangsstrook tussen kust en diepe zee. Voeding en gezondheid[bewerken] De kweek van zeesla is simpel. Zeesla wordt ook wel gebruikt in kruidentherapie en in preparaten voor huidverzorging.
Gourmet mushrooms in an old coffee cup The best part about this project is that it is dead simple and most of the materials can be acquired easily and for free. Really all you need is: Empty coffee cup(s) Enough coffee grounds to fill your cups Oyster mushroom spawn I'll assume you can manage to scare up some empty coffee cups. Ideally you want the little plastic lid part as well. It will make things simpler. Coffee grounds are really easy to procure. The mushroom spawn is something that you will probably have to buy.
Ultieme labbacterie telt 150.000 mutaties - NRC Het is de droom van biotechnologen: een bacterie die bijzondere stoffen kan produceren, maar toch volkomen veilig is. Onderzoekers van Harvard University hebben nu zo’n bacterie ontworpen, deels getest, maar nog niet gemonteerd. Deze vrijdag beschrijven ze het mijlpaaltje in Science. Genetisch gemodificeerde bacteriën worden al ingezet om op industriële schaal nuttige stoffen te produceren, zoals smaakstoffen, wasmiddel-enzymen en vaccins. Dat moet veiliger kunnen, vindt George Church van Harvard. ‘Herschreven’ bacteriën zouden de ultiem veilige biotech-bacteriën zijn. Al het leven op aarde deelt dezelfde genetische code. Hoe herschrijf je de genetische code? Er zijn 64 codons mogelijk (4x4x4). Deze synoniemen heeft Church in het vizier. Church heeft dat al eens voor elkaar gekregen met één codon. Het team is nu halverwege: ze hebben 63 procent van het genoom aangepast. Dat zou een echte doorbraak zijn.
Mushroom projects - My Edible Landscape 1. Maitake (Grifola frondosa) - spore print from Sam My plan is to germinate the spores in liquid culture, then inoculate cardboard, then bury around my chestnut trees. 2. Brick Cap [aka Kuritake - the Chestnut Mushroom] (Hypholoma sublateritium) - spore print from Sam My plan is to germinate the spores in liquid culture, then inoculate cardboard, then grow outside on wood chips. Tek1 - from Shroomery Have cloned kuritake, wine caps and shaggy manes to cardboard. Tk2 - from Bobcat at Mycotopia My outdoor patches were experimental, but both successful. Snipped from various sources… Great clusters of this species are often found on dead hardwoods, especially stumps, logs, and soils rich in wood debris. 3. Carboard Teks - from Shroomery, for growing oysters on cardboard. B.
Sea lettuce The sea lettuces comprise the genus Ulva, a group of edible green algae that is widely distributed along the coasts of the world's oceans. The type species within the genus Ulva is Ulva lactuca, lactuca being Latin for "lettuce". The genus also includes the species previously classified under the genus Enteromorpha,[1] the former members of which are known under the common name green nori.[2] Description[edit] Individual blades of Ulva can grow to be more than 400 mm (16 in) in size, but this only occurs when the plants are growing in sheltered areas. Nutrition and contamination[edit] Sea lettuce is eaten by a number of different sea animals, including manatees and the sea slugs known as sea hares. Aquarium trade[edit] Health concerns[edit] In August 2009, unprecedented amounts of these algae washed up on the beaches of Brittany, France, causing a major public health scare as it decomposed. Species[edit] Species in the genus Ulva include:[6] Accepted species Nomina dubia See also[edit] Seaweed
Mycology Resources Ulvophyceae Evolution[edit] The origin and early diversification of the Ulvophyceae likely took place in the late Neoproterozoic.[5][6] Although most contemporary ulvophytes are marine macroalgae (seaweeds), ancestral ulvophytes may have been freshwater, unicellular green algae. Molecular phylogenetic evidence suggests that macroscopic growth was achieved independently in the various major lineages of Ulvophyceae (Ulvales-Ulotrichales, Trentepohliales, Cladophorales, Bryopsidales and Dasycladales).[6] Current hypothesis on relationships among the main clades of Ulvophyceae[7][8] are shown below.
