Aplication of pumpkin skin flour Curcubitae sp. to improve the water quality performance and support shrimp Litopenaeus vannamei growth, it necessary do an analysis. Pumpkin as a source stimulants needed by bacteria survive in nitrification denitrification processes aquaculture alternative environmental friendly with bioremediation system evaluation. Its mesophilic nature organic ions for bacte...

The antimicrobial properties of essential oils have been demonstrated by various in vitro studies, whereas their effect on poultry farm hygiene has not been thoroughly investigated, in particular with reference to aerial treatment. The present study aims to assess the antibacterial effects of natural essential oils in broiler houses. Two experimental rooms were fogged with aqueous solutions of ...

Obligately anaerobic, mesophilic, cellulolytic bacteria were isolated from the wetwood of elm and maple trees. The isolation of these bacteria involved inoculation of selective enrichment cultures with increment cores taken from trees showing evidence of wetwood. Cellulolytic bacteria were present in the cores from seven of nine trees sampled, as indicated by the disappearance of cellulose from...

The microflora of raw milk is in the center constant attention at enterprises where it processed. Since microbiota pasteurized determined by percentage heat-resistant bacteria that are present material. Defects during storage associated with development residual products. aim work was to determine quantitative changes using different pasteurization temperatures. Pasteurization first and extra g...

Azospira suillum strain PS (formally Dechlorosoma suillum strain PS) is a metabolically versatile betaproteobacterium first identified for its ability to grow by dissimilatory reduction of perchlorate and chlorate [denoted (per)chlorate]. Together with Dechloromonas species, these two genera represent the dominant (per)chlorate-reducing bacteria in mesophilic freshwater environments. In additio...

In extreme environments varying from hot to cold, acidic to alkaline, and highly saline, mainly Archaea are found. Thermophilic and extremely acidophilic Archaea have a membrane that contains membrane spanning tetraether lipids. These tetra-ether membranes have a limited permeability for protons even at the high temperatures of growth and this property makes it possible for thermophilic archaea...

In the present study the effects on shelf life and sensory acceptance of gamma-irradiated refrigerated poultry breast fillets subjected to modified atmosphere packaging (80% CO2/20% N2 or vacuum) were investigated. After irradiation with 2 kGy, sensory acceptance tests and monitoring of bacterial growth were performed in order to determine the sanitary quality of the samples. It has been found ...

Kombucha is a slightly sweet, acidic, carbonated, fermented beverage obtained by fermenting sugared tea (Camellia sinesis) with symbiotic bacteria. In the present study, kombucha was produced from black sinensis), grape (Vitis labrusca), mulberry (Morus nigra), and rosehip (Rosa canina) fruits. Its physicochemical, microbiological, sensory properties antimicrobial effects were investigated. Dur...

Allochromatium vinosum formerly Chromatium vinosum is a mesophilic purple sulfur bacterium belonging to the family Chromatiaceae in the bacterial class Gammaproteobacteria. The genus Allochromatium contains currently five species. All members were isolated from freshwater, brackish water or marine habitats and are predominately obligate phototrophs. Here we describe the features of the organism...
