Ecological Systems, Closed
Systems that provide for the maintenance of life in an isolated living chamber through reutilization of the material available, in particular, by means of a cycle wherein exhaled carbon dioxide, urine, and other waste matter are converted chemically or by photosynthesis into oxygen, water, and food. (NASA Thesaurus, 1988)
Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.
Polymerase Chain Reaction
In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.

Brett geeks, come ride Trinitys Magical Brettanomyces Tour | DRAFT Magazine
Funky. Its the go-to word when describing beers fermented with Brettanomyces yeast rather than the traditional saccharomyces yeast. (For a run down on how the two differ, check out this mixed fermentation overview.) But like describing a beer as hoppy or malty, calling a beer funky doesnt acknowledge the full spectrum of Brett flavor. There are many Brett strains out there, each with its own calling cards: some are like wet hay; others smell of barnyard manure; still others impart fruit notes to a beer. For a wide-ranging taste of what the spectrum can be, Brett geeks should seek out Trinitys Magical Brettanomyces Tour, a series of seven cabernet barrel-aged saisons that all begin with the same base wort fermented by seven separate strains of Brett. Some are delicious; others are near-offensively manure-y. Its a sort of beer concept album, like Tommy or Yoshimi. Trinity began releasing the beers (one per month) in March in markets including Denver, Seattle, Portland, Columbus, and ...
Publication : USDA ARS
Citation: N/A Interpretive Summary: Technical Abstract: Brettanomyces (ascosporic state = Dekkera) are well recognized as spoilage yeasts in wine and cause mousiness, an undesirable odor and taste. Current methods for identification and enumeration take 1-2 weeks and rely on semi-selective culture medium followed by final identification from morphology and biochemical testing. A new in situ hybridization method using peptide nucleic acid (PNA) probes for simultaneous identification and enumeration of Brettanomyces within two days has been developed. The wine sample is filtered to isolate and separate individual microorganisms onto a membrane which is placed on a culture medium for up to 44 hours prior to testing. Microscopic colonies of Brettanomyces are detected on the membrane by hybridization with peroxidase-labeled PNA probes targeting Brettanomyces 26S rRNA. Excess probe is removed by washing and hybridized probe is visualized by a chemiluminescent reaction. Each Brettanomyces ...

How to drink through the Fat Tire & Friends pack | New Belgium Brewing
We really wanted to do something special in celebration of New Belgiums 25th anniversary, so we got together with friends from five different breweries, gave them the keys to the Fat Tire recipe, and said, Surprise us. The result is Fat Tire & Friends, a collaborative variety pack featuring five unique spins on the original fave, plus a couple bottles of Fat Tire for good measure.. This is the wildest pack weve ever released, and probably the wildest variety pack of the year. Theres Avery Fat Wild Ale (brewed with Brettanomyces Bruxellensis Drie), Allagash Fat Funk Ale (bottle conditioned with Brettanomyces Allagagensis), Hopworks Fat Sour Apple Ale (brewed with Lactobacillus and apple juice), Rhinegeist Fat Pale Ale (with Belgian yeast and fruity hops) and Firestone Walker Fat Hoppy Ale (featuring the likes of Mosaic, Citra and Mandarina Bavaria hops). And, of course, the original Fat Tire. Sure theres a lot going on, but fear not: There are methods for tackling such a bold variety pack. ...
Firestone Walker Releases 2015 Feral One | Brewbound
The 2015 Feral One is a blend of Vintage Solace (43%), a wild wheat ale aged between 16 and 48 months in French and American oak; Agrestic (43%), an American wild red ale aged between 24 and 28 months in French oak; and Lil Opal (14%), a brettd saison aged for 26 months in French oak. Microflora accomplices included Brettanomyces Lambicus, Brettanomyces Bruxellensis and Lactobacillus Brevis.. The bulk of this blend has been aging for two to four years in oak barrels, and the resulting complexity really shows on the palate, said Master Blender Jim Crooks.. The 2015 Feral One begins with an earthy funky nose that gives way to estery notes of dried apricots, strawberry, guava and slight orange zest. Mature toasted oak, lavender, vanilla and cinnamon lurk in the background. Mouthwatering acidity and soft tannins are punctuated by firm carbonation..

Yeast and bacteria 101: Brettanomyces, lactobacillus, pediococcus | DRAFT
If youre a fan of sour beers, youve definitely seen some tough-to-spell bacteria and yeast names thrown around. Brett, lacto and pedio are sort of the Three Musketeers of sour beers, producing some of the flavors that make beers distinctly funky, sour and tart. (I spotted a guy at Uplands Sour, Wild & Funk Fest two years ago wearing this shirt. Well played, sir.) Though people often refer to these bacteria and yeast in the same breath, its worth taking time to explore each on its own. I asked Michael Dawson, brand manager at Wyeast Laboratories, which supplies liquid brewing cultures, for the lowdown on what each microbe does.. To understand these three terms, though, we need to begin with the two types of fermentation: wild and single-culture. Single-culture means one strain of yeast is introduced to eat up the sugars in wort, converting them to alcohol. Sour beers, on the other hand, undergo wild or mixed fermentation, meaning multiple types of yeast and bacteria work together ...

Brettanomyces/Dekkera is considered as one of the main causes of microbial spoilage and sensory deviations of red wines. This work compares the sensitivity and effectiveness of conventional microbiological culture and real-time polymerase chain reaction (Q-PCR) methods for Brettanomyces/Dekkera detection and quantification and demonstrates a positive correlation between both methods. Moreover, an improved DNA extraction protocol enabled quantification of Brettanomyces/Dekkera cells by Q-PCR down to 20 cells/mL in turbid wines in a total of 324 red wine samples. The conventional culture analysis is time-consuming but has lower cost than Q-PCR, and it is simple and efficient in quantifying viable Brettanomyces/Dekkera cells. ...

Profiling Potentially Smoke Tainted Red Wines: Volatile Phenols and Aroma Attributes
INTRODUCTION. In order to establish and maintain strong, positive international brands in a fiercely competitive market, it is important that wine producers understand the character of their products and ensure consistency of required sensory features. Negative attributes in red wine, for example, smoke taint, ashiness, greenness / herbaceousness and burnt rubber (BR) have been discussed by various authors (Goode, 2008; Hammond, 2015; Heyns, 2014) and necessitate the investigation of compounds associated with these descriptors.. Volatile phenols (VPs) are a group of compounds that have been associated with smoky, burnt and acrid attributes (Parker, et al., 2013). Their presence in wine may derive from a number of sources including grapes and yeast, in particular the Brettanomyces species (Romano et al., 2009; Weiss, 2014). Wood maturation has been found to contribute to the pool of VPs (Boidron et al., 1988; Prida & Chatonnet, 2010), with the cresols, as well as 3, 4-dimethylphenol ...
Tasting Beer to Learn About Yeast - All About Beer
The lambic breweries around Brussels still practice spontaneous fermentation with wild yeast. The sour, barnyard flavor of a lambic doesnt rely on a single yeast strain: it is created by a cocktail of Brettanomyces yeast and bacteria.. An alternative approach to a yeast tasting is to sample all the beer styles from a single brewery. Once you ignore the flavor differences of the various styles, the underlying similarity between the beers is due to the house yeast. Full Sail house yeast, for example, has a peachy ester that emerges in all their beers. The Shipyard Brewing Co. of Maine, uses the fruity, orangey, distinctive Ringwood yeast strain, named for Ringwood Brewery, Englands first micro.. ...
Artisanal Imports Elgoods Coolship Sour Mango Ale On Shelves Now Nationwide - Artisanal Imports
North America (September 21, 2017) - Elgoods Coolship Sour Mango Ale - a tart, 6% ABV, spontaneously-fermented ale blended with mango for a bright and fruity flavor mélange, is now available nationwide in the U.S.. The Sour Mango Ale is the first bottle release in the renowned Elgoods Coolship Series, formerly known as Original Sour, a collaborative project between head brewer Alan Pateman and Artisanal CEO Bob Leggett featuring 100% spontaneously fermented beers from a most unlikely source: a traditional British Brewery!. Not just a kettle sour, Elgoods uses copper coolships from the 1920s to cool their wort overnight. These traditional fermentation vessels are broad and flat with open tops - accelerating the cooling process while also inoculating the wort with a healthy mix of microbes. As the wort cools, it becomes the perfect home for lactobacilli, which are responsible for the bright sourness. Brettanomyces and other wild yeasts add earthy notes and saccharomyces cerevisiae, or ...

Beers | Urban Artifact
Wild, funky, tart, mouthwatering and gossip worthy: Things used to describe the latest pop star gone rogue and more rarely used to describe style-defying beers. Every sip of beer you drink is an experience, much like our taproom, music lounge, performance venue, beer garden, and music label, and each one of the unique shows or performances you attend. Our beers are inspired by our lifestyle, by the culture and community that we define, and by the microscopic natural world around us. We brew beers that cant be tamed, that never fail to refresh the body and spirit, and that require one to experience the liquid in their glass.. Like us, all our beers are wild. That means, in one way or the other, each and every one of our beers is brewed with locally caught wild yeast, bacteria, or mixed cultures of both. With micro-floral creatures such as Saccharomyces, Lactobacillus, Pediococcus, and Brettanomyces, it is the brewers job to get these wild microorganisms to create flavors that are tart and ...

Saison Dupont Bottle Culture - Yeast Review - In Bounds Brewing
Saison Dupont is almost universally regarded as the premier example of bitter saison in the world. Its spicy, citrusy, dry, bitter, and ages extremely well. Its no wonder that virtually every homebrew yeast supplier has some derivative of Dupont yeast in their library, and there is no shortage of posts online about using these strains.. The bad news is that you are just about as likely to run into a story about WLP565 or WY3724 stalling out at a high FG as you are about a successful ferment. Even the successful ferments with single strain Dupont yeast are often lacking in a particular character and may exhibit off flavors like acetaldehyde.. Enter the idea of culturing yeast from bottles of Dupont. Yvan de Baets in Farmhouse Ales indicates that there are at least 4 strains of yeast in the Dupont house culture, if not more. He also indicates that he thinks that some of them are Brettanomyces strains. If this is indeed the case, it might explain the stalling from single strains and the lack of ...

P. 101-105. Interpretive Summary: More than 10 million tons of rock salt are poured onto North American highways each year to provide safer driving conditions during the winter months. This heavy use of de-icing chemical destroys roadside vegetation, damages aquatic ecosystems, pollutes groundwater and domestic potable water supplies, and damages the highway infrastructure. Calcium magnesium acetate (CMA) has been identified as a potentially acceptable, non-corrosive, environmentally benign alternative to road salt. CMA is a mixture of calcium acetate and magnesium acetate and is manufactured by reacting glacial acetic acid with dolomitic lime (CaO-MgO) or limestone (Ca/MgCO3). Currently, the commercial production of glacial acetic acid is exclusively by petrochemical routes and amounted to an ...

Beervana: What Sours a Beer?
As alluded to above, pediococcus is the beastie that gives lambics their lactic, not lactobacillus. This is mainly a function of the life cycle of a lambic. Pediococcus ferments in beer with little or no oxygen; likewise, it gives off no carbon dioxide. In a lambic, the pediococcus kicks in after 3-4 months when, fascinatingly, the wort is exceptionally sour as a result of early enterobacter production. The pediococcus begins when the lambic warms up, creating long strands of slime on top of the wort. You can drink the beer at this stage, but its oily and known as the sick stage. But from the sickness comes the lactic, and eventually, the slime is reabsorbed as the brettanomyces begin gobbling up everything thats left ...
Molecular tracing of aquatic viruses: where epidemiology needs to meet genomics | Frontiers Research Topic
Aquatic viruses constitute major threats for sustainable aquaculture production of both fish and shellfish worldwide. Thus, considerable resources are constantly invested in controlling the spread of viral pathogens in aquaculture. These control strategies have been primarily designed according to general biosecurity rules, mainly because disease-specific transmission patterns are still poorly understood. This leads to compromised efficiency of preventive interventions. A variety of pathways for the spread of pathogens between aquaculture stocks have been suggested, e.g. horizontal and vertical transmission, passive drift in the water, or commercial trade of live animals. These different routes of propagation are prone to facilitate the quick mix of isolates from different geographic origins, which subsequently co-occur within populations. In this particular context, analysis of outbreaks requires typing methods that offer a high level of strain discrimination. Among these, whole genome sequencing not

Saccharomyces and Brettanomyces create more than just ethanol and carbon dioxide during fermentation. Metabolic compounds can enhance beer flavor (e.g. fruitiness, spiciness) or detract from it (e.g. vegetal, fusel). Additional organisms can complicate these profiles.

Modified Nitrate Assimilation Agar
The ability to utilize nitrate as a sole source of nitrogen is an important taxonomic indicator of some species. Previous research by Hipkin has grouped yeasts on the basis of nitrate utilization, with some species being able to assimilate nitrate ( Brettanomyces, Candida, Hansenula, Pachysolen, and Rhodotorula ) while others are not ( Kluyveromyces, Pichia, Saccharomyces and Schizosaccharomyces ). (8) Nitrate assimilation is defined simply as the utilization of a nitrogen source by a microorganism in the presence of oxygen. A positive reaction is indicated by the presence of growth or the use of a pH indicator in the medium. The indicator method is a modification of the Wickerham method that was devised by Adams and Cooper. (7) The use of this method is easier to read than conventional techniques, yet it is equally as reliable. (7) Additionally, this method is not affected by carry-over of the inoculum. Hardy Diagnostics Modified Nitrate Assimilation Agar contains a yeast carbon base composed ...

Once the drug test comes out positive but you deny using any drugs, youll be ...
Biocontrol of Green Mold of Orange using Some Yeasts Strains and their Effects on Postharvest Quality Parameters
Abstract: Three isolates of yeasts, Candida sake (Cs), Pichia gluilliermondii (Pg) and Pichia membranifaciens (Pm) were evaluated for their activities in reducing postharvest green mold decay of orange fruits caused by Penicillium digitatum. In vitro experiments, all tested isolates inhibit the growth of Penicillium digitatum. In vivo experiments, treating fruits 15 days before harvest and after harvest or only after harvest (natural and artificial infection of fruits) by three isolates of yeasts significantly reduced the disease severity in natural and artificial infection of fruits compared with untreated fruits (control). Pichia gluilliermondii (Pg) was the best yeast than others isolates in controlling the disease in artificial infection. All treatments significantly decreased fruit weight loss percentage (%) for nine weeks comparing with control. Results also indicated that all isolates significantly reduced the undesirable fruits percentage during cooling storage period (5°C) compared ...
Kinetics and regulation of fructose and glucose transport systems are responsible for fructophily in Zygosaccharomyces bailii |...
A strain of Zygosaccharomyces bailii was selected for studies on fructose and glucose transport to determine the basis of the fructophilic behaviour of this species. Fructose was transported by a specific low-affinity, high-capacity transport system with a K m of 65.6 mM and a V max of 6.7 mmol g-1 h-1 for cells grown on 2% (w/v) fructose, while the transport of glucose showed a K m of 7 mM and a V max of 1.7 mmol g-1 h-1 for cells grown on 2% (w/v) glucose. The transporter of glucose also fructose as a substrate. Fructose inactivated the glucose transporter; inactivation was faster at higher concentrations. Both transporters were partially inductive. Measurements of metabolic fluxes and respiration and fermentation rates supported the general features identified by transport measurements. The kinetics and regulation of transport of the two sugars confirm the fructophilic behaviour previously described by other authors.
