Immobilization patterns and dynamics of acetate-utilizing methanogens immobilized in sterile granular sludge in upflow anaerobic sludge blanket reactors. (1/50)

Sterile granular sludge was inoculated with either Methanosarcina mazeii S-6, Methanosaeta concilii GP-6, or both species in acetate-fed upflow anaerobic sludge blanket (UASB) reactors to investigate the immobilization patterns and dynamics of aceticlastic methanogens in granular sludge. After several months of reactor operation, the methanogens were immobilized, either separately or together. The fastest immobilization was observed in the reactor containing M. mazeii S-6. The highest effluent concentration of acetate was observed in the reactor with only M. mazeii S-6 immobilized, while the lowest effluent concentration of acetate was observed in the reactor where both types of methanogens were immobilized together. No changes were observed in the kinetic parameters (Ks and mumax) of immobilized M. concilii GP-6 or M. mazeii S-6 compared with suspended cultures, indicating that immobilization does not affect the growth kinetics of these methanogens. An enzyme-linked immunosorbent assay using polyclonal antibodies against either M. concilii GP-6 or M. mazeii S-6 showed significant variations in the two methanogenic populations in the different reactors. Polyclonal antibodies were further used to study the spatial distribution of the two methanogens. M. concilii GP-6 was immobilized only on existing support material without any specific pattern. M. mazeii S-6, however, showed a different immobilization pattern: large clumps were formed when the concentration of acetate was high, but where the acetate concentration was low this strain was immobilized on support material as single cells or small clumps. The data clearly show that the two aceticlastic methanogens immobilize differently in UASB systems, depending on the conditions found throughout the UASB reactor.  (+info)

Isolation and characterization of Methanomethylovorans hollandica gen. nov., sp. nov., isolated from freshwater sediment, a methylotrophic methanogen able to grow on dimethyl sulfide and methanethiol. (2/50)

A newly isolated methanogen, strain DMS1(T), is the first obligately anaerobic archaeon which was directly enriched and isolated from a freshwater sediment in defined minimal medium containing dimethyl sulfide (DMS) as the sole carbon and energy source. The use of a chemostat with a continuous DMS-containing gas stream as a method of enrichment, followed by cultivation in deep agar tubes, resulted in a pure culture. Since the only substrates utilized by strain DMS1(T) are methanol, methylamines, methanethiol (MT), and DMS, this organism is considered an obligately methylotrophic methanogen like most other DMS-degrading methanogens. Strain DMS1(T) differs from all other DMS-degrading methanogens, since it was isolated from a freshwater pond and requires NaCl concentrations (0 to 0.04 M) typical of the NaCl concentrations required by freshwater microorganisms for growth. DMS was degraded effectively only in a chemostat culture in the presence of low hydrogen sulfide and MT concentrations. Addition of MT or sulfide to the chemostat significantly decreased degradation of DMS. Transient accumulation of DMS in MT-amended cultures indicated that transfer of the first methyl group during DMS degradation is a reversible process. On the basis of its low level of homology with the most closely related methanogen, Methanococcoides burtonii (94.5%), its position on the phylogenetic tree, its morphology (which is different from that of members of the genera Methanolobus, Methanococcoides, and Methanohalophilus), and its salt tolerance and optimum (which are characteristic of freshwater bacteria), we propose that strain DMS1(T) is a representative of a novel genus. This isolate was named Methanomethylovorans hollandica. Analysis of DMS-amended sediment slurries with a fluorescence microscope revealed the presence of methanogens which were morphologically identical to M. hollandica, as described in this study. Considering its physiological properties, M. hollandica DMS1(T) is probably responsible for degradation of MT and DMS in freshwater sediments in situ. Due to the reversibility of the DMS conversion, methanogens like strain DMS1(T) can also be involved in the formation of DMS through methylation of MT. This phenomenon, which previously has been shown to occur in sediment slurries of freshwater origin, might affect the steady-state concentrations and, consequently, the total flux of DMS and MT in these systems.  (+info)

Effect of temperature on stability and activity of elongation factor 2 proteins from Antarctic and thermophilic methanogens. (3/50)

Despite the presence and abundance of archaea in low-temperature environments, little information is available regarding their physiological and biochemical properties. In order to investigate the adaptation of archaeal proteins to low temperatures, we purified and characterized the elongation factor 2 (EF-2) protein from the Antarctic methanogen Methanococcoides burtonii, which was expressed in Escherichia coli, and compared it to the recombinant EF-2 protein from a phylogenetically related thermophile, Methanosarcina thermophila. Using differential scanning calorimetry to assess protein stability and enzyme assays for the intrinsic GTPase activity, we identified biochemical and biophysical properties that are characteristic of the cold-adapted protein. This includes a higher activity at low temperatures caused by a decrease of the activation energy necessary for GTP hydrolysis and a decreased activation energy for the irreversible denaturation of the protein, which indicates a less thermostable structure. Comparison of the in vitro properties of the proteins with the temperature-dependent characteristics of growth of the organisms indicates that additional cytoplasmic factors are likely to be important for the complete thermal adaptation of the proteins in vivo. This is the first study to address thermal adaptation of proteins from a free-living, cold-adapted archaeon, and our results indicate that the ability of the Antarctic methanogen to adapt to the cold is likely to involve protein structural changes.  (+info)

Glycine betaine transport in the obligate halophilic archaeon Methanohalophilus portucalensis. (4/50)

Transport of the osmoprotectant glycine betaine was investigated using the glycine betaine-synthesizing microbe Methanohalophilus portucalensis (strain FDF1), since solute uptake for this class of obligate halophilic methanogenic Archaea has not been examined. Betaine uptake followed a Michaelis-Menten relationship, with an observed K(t) of 23 microM and a V(max) of 8 nmol per min per mg of protein. The transport system was highly specific for betaine: choline, proline, and dimethylglycine did not significantly compete for [(14)C]betaine uptake. The proton-conducting uncoupler 2, 4-dinitrophenol and the ATPase inhibitor N, N-dicyclohexylcarbodiimide both inhibited glycine betaine uptake. Growth of cells in the presence of 500 microM betaine resulted in faster cell growth due to the suppression of the de novo synthesis of the other compatible solutes, alpha-glutamate, beta-glutamine, and N(epsilon)-acetyl-beta-lysine. These investigations demonstrate that this model halophilic methanogen, M. portucalensis strain FDF1, possesses a high-affinity and highly specific betaine transport system that allows it to accumulate this osmoprotectant from the environment in lieu of synthesizing this or other osmoprotectants under high-salt growth conditions.  (+info)

Effects of ribosomes and intracellular solutes on activities and stabilities of elongation factor 2 proteins from psychrotolerant and thermophilic methanogens. (5/50)

Low-temperature-adapted archaea are abundant in the environment, yet little is known about the thermal adaptation of their proteins. We have previously compared elongation factor 2 (EF-2) proteins from Antarctic (Methanococcoides burtonii) and thermophilic (Methanosarcina thermophila) methanogens and found that the M. burtonii EF-2 had greater intrinsic activity at low temperatures and lower thermal stability at high temperatures (T. Thomas and R. Cavicchioli, J. Bacteriol. 182:1328-1332, 2000). While the gross thermal properties correlated with growth temperature, the activity and stability profiles of the EF-2 proteins did not precisely match the optimal growth temperature of each organism. This indicated that intracellular components may affect the thermal characteristics of the EF-2 proteins, and in this study we examined the effects of ribosomes and intracellular solutes. At a high growth temperature the thermophile produced high levels of potassium glutamate, which, when assayed in vitro with EF-2, retarded thermal unfolding and increased catalytic efficiency. In contrast, for the Antarctic methanogen adaptation to growth at a low temperature did not involve the accumulation of stabilizing organic solutes but appeared to result from an increased affinity of EF-2 for GTP and high levels of EF-2 in the cell relative to its low growth rate. Furthermore, ribosomes greatly stimulated GTPase activity and moderately stabilized both EF-2 proteins. These findings illustrate the different physiological strategies that have evolved in two phylogenetically related but thermally distinct methanogens to enable EF-2 to function satisfactorily.  (+info)

Microbial populations involved in cycling of dimethyl sulfide and methanethiol in freshwater sediments. (6/50)

Although several microorganisms that produce and degrade methanethiol (MT) and dimethyl sulfide (DMS) have been isolated from various habitats, little is known about the numbers of these microorganisms in situ. This study reports on the identification and quantification of microorganisms involved in the cycling of MT and DMS in freshwater sediments. Sediment incubation studies revealed that the formation of MT and DMS is well balanced with their degradation. MT formation depends on the concentrations of both sulfide and methyl group-donating compounds. A most-probable number (MPN) dilution series with syringate as the growth substrate showed that methylation of sulfide with methyl groups derived from syringate is a commonly occurring process in situ. MT appeared to be primarily degraded by obligately methylotrophic methanogens, which were found in the highest positive dilutions on DMS and mixed substrates (methanol, trimethylamine [TMA], and DMS). Amplified ribosomal DNA restriction analysis (ARDRA) and 16S rRNA gene sequence analysis of the total DNA isolated from the sediments and of the DNA isolated from the highest positive dilutions of the MPN series (mixed substrates) revealed that the methanogens that are responsible for the degradation of MT, DMS, methanol, and TMA in situ are all phylogenetically closely related to Methanomethylovorans hollandica. This was confirmed by sequence analysis of the product obtained from a nested PCR developed for the selective amplification of the 16S rRNA gene from M. hollandica. The data from sediment incubation experiments, MPN series, and molecular-genetics detection correlated well and provide convincing evidence for the suggested mechanisms for MT and DMS cycling and the common presence of the DMS-degrading methanogen M. hollandica in freshwater sediments.  (+info)

Transfer of Methanolobus siciliae to the genus Methanosarcina, naming it Methanosarcina siciliae, and emendation of the genus Methanosarcina. (7/50)

A sequence analysis of the 16S rRNA of Methanolobus siciliae T4/M(T) (T = type strain) showed that this strain is closely related to members of the genus Methanosarcina, especially Methanosarcina acetivorans C2A(T). Methanolobus siciliae T4/M(T) and HI350 were morphologically more similar to members of the genus Methanosarcina than to members of the genus Methanolobus in that they both formed massive cell aggregates with pseudosarcinae. Thus, we propose that Methanolobus siciliae should be transferred to the genus Methanosarcina as Methanosarcina siciliae.  (+info)

Bacteria and Archaea physically associated with Gulf of Mexico gas hydrates. (8/50)

Although there is significant interest in the potential interactions of microbes with gas hydrate, no direct physical association between them has been demonstrated. We examined several intact samples of naturally occurring gas hydrate from the Gulf of Mexico for evidence of microbes. All samples were collected from anaerobic hemipelagic mud within the gas hydrate stability zone, at water depths in the ca. 540- to 2,000-m range. The delta(13)C of hydrate-bound methane varied from -45.1 per thousand Peedee belemnite (PDB) to -74.7 per thousand PDB, reflecting different gas origins. Stable isotope composition data indicated microbial consumption of methane or propane in some of the samples. Evidence of the presence of microbes was initially determined by 4,6-diamidino 2-phenylindole dihydrochloride (DAPI) total direct counts of hydrate-associated sediments (mean = 1.5 x 10(9) cells g(-1)) and gas hydrate (mean = 1.0 x 10(6) cells ml(-1)). Small-subunit rRNA phylogenetic characterization was performed to assess the composition of the microbial community in one gas hydrate sample (AT425) that had no detectable associated sediment and showed evidence of microbial methane consumption. Bacteria were moderately diverse within AT425 and were dominated by gene sequences related to several groups of Proteobacteria, as well as Actinobacteria and low-G + C Firmicutes. In contrast, there was low diversity of Archaea, nearly all of which were related to methanogenic Archaea, with the majority specifically related to Methanosaeta spp. The results of this study suggest that there is a direct association between microbes and gas hydrate, a finding that may have significance for hydrocarbon flux into the Gulf of Mexico and for life in extreme environments.  (+info)

Methanosarcinaceae is a family of archaea within the order Methanosarcinales. These organisms are known for their ability to produce methane as a metabolic byproduct, specifically through the process of methanogenesis. They are commonly found in anaerobic environments such as wetlands, digestive tracts of animals, and sewage treatment facilities.

Methanosarcinaceae species are unique among methanogens because they can utilize a variety of substrates for methane production, including acetate, methanol, and carbon dioxide with hydrogen. This versatility allows them to thrive in diverse anaerobic habitats. Some notable genera within this family include Methanosarcina, Methanosaeta, and Methanothrix.

It is important to note that methanogens like those found in Methanosarcinaceae play a significant role in the global carbon cycle, contributing to greenhouse gas emissions and climate change. Additionally, they have potential applications in biotechnology for waste treatment and biofuel production.

Methanosarcinales is an order of methanogenic archaea within the phylum Euryarchaeota. These are microorganisms that produce methane as a metabolic byproduct in anaerobic environments. Members of this order are distinguished by their ability to use multiple substrates for methanogenesis, including acetate, methanol, and methylamines, in addition to carbon dioxide and hydrogen. They often form part of the microbial community in habitats such as wetlands, digestive tracts of animals, and anaerobic waste treatment systems.

Archaeal DNA refers to the genetic material present in archaea, a domain of single-celled microorganisms lacking a nucleus. Like bacteria, archaea have a single circular chromosome that contains their genetic information. However, archaeal DNA is significantly different from bacterial and eukaryotic DNA in terms of its structure and composition.

Archaeal DNA is characterized by the presence of unique modifications such as methylation patterns, which help distinguish it from other types of DNA. Additionally, archaea have a distinct set of genes involved in DNA replication, repair, and recombination, many of which are more similar to those found in eukaryotes than bacteria.

One notable feature of archaeal DNA is its resistance to environmental stressors such as extreme temperatures, pH levels, and salt concentrations. This allows archaea to thrive in some of the most inhospitable environments on Earth, including hydrothermal vents, acidic hot springs, and highly saline lakes.

Overall, the study of archaeal DNA has provided valuable insights into the evolutionary history of life on Earth and the unique adaptations that allow these organisms to survive in extreme conditions.

Methane is not a medical term, but it is a chemical compound that is often mentioned in the context of medicine and health. Medically, methane is significant because it is one of the gases produced by anaerobic microorganisms during the breakdown of organic matter in the gut, leading to conditions such as bloating, cramping, and diarrhea. Excessive production of methane can also be a symptom of certain digestive disorders like irritable bowel syndrome (IBS) and small intestinal bacterial overgrowth (SIBO).

In broader terms, methane is a colorless, odorless gas that is the primary component of natural gas. It is produced naturally by the decomposition of organic matter in anaerobic conditions, such as in landfills, wetlands, and the digestive tracts of animals like cows and humans. Methane is also a potent greenhouse gas with a global warming potential 25 times greater than carbon dioxide over a 100-year time frame.

Euryarchaeota is a phylum within the domain Archaea, which consists of a diverse group of microorganisms that are commonly found in various environments such as soil, oceans, and the digestive tracts of animals. This group includes methanogens, which are archaea that produce methane as a metabolic byproduct, and extreme halophiles, which are archaea that thrive in highly saline environments.

The name Euryarchaeota comes from the Greek words "eury," meaning wide or broad, and "archaios," meaning ancient or primitive. This name reflects the phylum's diverse range of habitats and metabolic capabilities.

Euryarchaeota are characterized by their unique archaeal-type cell walls, which contain a variety of complex polysaccharides and proteins. They also have a distinct type of intracellular membrane called the archaellum, which is involved in motility. Additionally, Euryarchaeota have a unique genetic code that differs from that of bacteria and eukaryotes, with some codons specifying different amino acids.

Overall, Euryarchaeota are an important group of archaea that play a significant role in global carbon and nitrogen cycles, as well as in the breakdown of organic matter in various environments.

Ribosomal RNA (rRNA) is a type of RNA that combines with proteins to form ribosomes, which are complex structures inside cells where protein synthesis occurs. The "16S" refers to the sedimentation coefficient of the rRNA molecule, which is a measure of its size and shape. In particular, 16S rRNA is a component of the smaller subunit of the prokaryotic ribosome (found in bacteria and archaea), and is often used as a molecular marker for identifying and classifying these organisms due to its relative stability and conservation among species. The sequence of 16S rRNA can be compared across different species to determine their evolutionary relationships and taxonomic positions.

Biofuels are defined as fuels derived from organic materials such as plants, algae, and animal waste. These fuels can be produced through various processes, including fermentation, esterification, and transesterification. The most common types of biofuels include biodiesel, ethanol, and biogas.

Biodiesel is a type of fuel that is produced from vegetable oils or animal fats through a process called transesterification. It can be used in diesel engines with little or no modification and can significantly reduce greenhouse gas emissions compared to traditional fossil fuels.

Ethanol is a type of alcohol that is produced through the fermentation of sugars found in crops such as corn, sugarcane, and switchgrass. It is typically blended with gasoline to create a fuel known as E85, which contains 85% ethanol and 15% gasoline.

Biogas is a type of fuel that is produced through the anaerobic digestion of organic materials such as food waste, sewage sludge, and agricultural waste. It is composed primarily of methane and carbon dioxide and can be used to generate electricity or heat.

Overall, biofuels offer a renewable and more sustainable alternative to traditional fossil fuels, helping to reduce greenhouse gas emissions and decrease dependence on non-renewable resources.

I'm happy to help, but I must clarify that I can't provide a "medical definition" of waste management since it is not a medical term per se. Waste management is a broader environmental and public health issue. However, I can offer a definition related to healthcare facilities:

Waste management in the context of healthcare facilities refers to the practices, processes, and systems used to collect, transport, treat, dispose, recycle, or reuse waste materials generated from healthcare activities. This includes various types of waste such as hazardous (e.g., infectious, chemical, pharmaceutical), non-hazardous, and radioactive waste. Proper management is crucial to prevent infection, protect the environment, conserve resources, and ensure occupational safety for healthcare workers and the public.

A bioreactor is a device or system that supports and controls the conditions necessary for biological organisms, cells, or tissues to grow and perform their specific functions. It provides a controlled environment with appropriate temperature, pH, nutrients, and other factors required for the desired biological process to occur. Bioreactors are widely used in various fields such as biotechnology, pharmaceuticals, agriculture, and environmental science for applications like production of therapeutic proteins, vaccines, biofuels, enzymes, and wastewater treatment.

Anaerobiosis is a state in which an organism or a portion of an organism is able to live and grow in the absence of molecular oxygen (O2). In biological contexts, "anaerobe" refers to any organism that does not require oxygen for growth, and "aerobe" refers to an organism that does require oxygen for growth.

There are two types of anaerobes: obligate anaerobes, which cannot tolerate the presence of oxygen and will die if exposed to it; and facultative anaerobes, which can grow with or without oxygen but prefer to grow in its absence. Some organisms are able to switch between aerobic and anaerobic metabolism depending on the availability of oxygen, a process known as "facultative anaerobiosis."

Anaerobic respiration is a type of metabolic process that occurs in the absence of molecular oxygen. In this process, organisms use alternative electron acceptors other than oxygen to generate energy through the transfer of electrons during cellular respiration. Examples of alternative electron acceptors include nitrate, sulfate, and carbon dioxide.

Anaerobic metabolism is less efficient than aerobic metabolism in terms of energy production, but it allows organisms to survive in environments where oxygen is not available or is toxic. Anaerobic bacteria are important decomposers in many ecosystems, breaking down organic matter and releasing nutrients back into the environment. In the human body, anaerobic bacteria can cause infections and other health problems if they proliferate in areas with low oxygen levels, such as the mouth, intestines, or deep tissue wounds.

Sewage is not typically considered a medical term, but it does have relevance to public health and medicine. Sewage is the wastewater that is produced by households and industries, which contains a variety of contaminants including human waste, chemicals, and other pollutants. It can contain various pathogens such as bacteria, viruses, and parasites, which can cause diseases in humans if they come into contact with it or consume contaminated food or water. Therefore, the proper treatment and disposal of sewage is essential to prevent the spread of infectious diseases and protect public health.

"Manure" is not a term typically used in medical definitions. However, it is commonly referred to in agriculture and horticulture. Manure is defined as organic matter, such as animal feces and urine, that is used as a fertilizer to enrich and amend the soil. It is often rich in nutrients like nitrogen, phosphorus, and potassium, which are essential for plant growth. While manure can be beneficial for agriculture and gardening, it can also pose risks to human health if not handled properly due to the potential presence of pathogens and other harmful substances.

  • In taxonomy, the Methanosarcinaceae are a family of the Methanosarcinales. (wikipedia.org)
  • Sequence analyses revealed a distinct diversity of methanogenic archaea affiliated to Methanomicrobiaceae, Methanosarcinaceae and Methanosaetaceae. (awi.de)
  • Archaea accounted for 2.26% of the total prokaryotic community, with their community dominated by Methanobacteriaceae (82%), followed by Methanomassiliicoccaceae , and Methanosarcinaceae . (dzumenvis.nic.in)
  • The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI) A notable trait of Methanosarcinaceae is that they are methanogens that incorporate the unusual amino acid pyrrolysine into their enzymes. (wikipedia.org)
  • The methanogens existing in the system were mostly thermo-tolerant acetate-utilizing methanogens, and specifically from Methanosarcinaceae species. (scirp.org)
