  • Characterization of selected nutrients and bacteria from anaerobic swine manure lagoons on sow, nursery, and finisher farms in the Mid-South USA

    Received for publication October 31, 2008. Swine (Sus scrofa domestica) production in the Mid-South USA comprises sow, nursery, and finisher farms. A 2007 packing plant closure started a regional shift from finisher to sow and nursery farms. Changes in manure stored in lagoons and land-applied as fertilizer were expected but were unknown because nutrient and bacterial levels had not been ...

  • What is it about this soil that protects plants from devastating disease?

    Figuring out why certain soils keep plant parasites at bay could be a boon for agriculture around the globe Plants around the world are constantly under attack — often with big implications for humans. In the 1960s, millions of elm trees in Britain, France and the U.S. fell victim to Dutch elm disease, which clogs the vessels that carry life-giving water to the trees’ leaves. ...

  • Review: Effects of olive mill wastewater application on soil properties and plants growth

    Comparative effects of untreated olive mill wastewater (UOMW), treated olive mill wastewater (TOMW) and bioaugmented olive mill wastewater (BOMW) on soil properties, on seeds germination and on plants growth were investigated. The water holding capacity, the salinity, the organic carbon content, humus, total nitrogen, phosphate and potassium increased when the spread amounts of UOMW (50, 100 and ...

  • Antimicrobial resistance in escherichia coli isolated in wastewater and sludge from poultry slaughterhouse wastewater plants

    The authors investigated the antimicrobial resistance of Escherichia coli isolates in 22 samples of crude inflow, treated effluent, and sludge collected at the wastewater treatment plants of eight poultry slaughterhouses in Portugal. A total of 549 E. coli strains were recovered and tested for resistance to 12 antimicrobial agents. Multidrug resistance was present in 55.7 percent of the isolates. ...

  • Organic Soil for Healthy Crops and Gardens, Black Worm Castings, Vermaplex

    Creating a healthy organic garden is easier than you think. It all starts with the soil. As a gardener or farmer your goal is healthy plants that yield plentiful of flowers, fruits and vegetables. Your first priority should be the soil, it is the key ingredient to a thriving garden. Plants receive their nutrients from the soil. They are dependent on a soil full of ...

  • Technical note: Quorum sensing

    Quorum sensing, or the control of gene expression in response to cell density, is used by both gram negative and gram positive bacteria to regulate a variety of physiological functions including bioluminescence, swarming, antibiotic biosynthesis, plasmid conjugal transfer and the production of virulence determinants in animal, fish and plant pathogens. In all cases, quorum sensing involves the ...

  • Microbial communities of Solanum tuberosum and magainin-producing transgenic lines

    Antimicrobial peptide magainin II, isolated from the skin of the African clawed toad, has shown activity in vitro against a range of micro-organisms. Transgenic potato lines expressing a synthetic magainin gene show improved resistance to the bacterial plant pathogen, Erwinia carotovora. Culturable bacterial and fungal communities associated with magainin-producing potato plants were compared ...

  • Bacterial communities associated with the rhizosphere of transgenic Bt 176 maize (Zea mays) and its non transgenic counterpart

    The effect of transgenic Bt 176 maize on the rhizosphere bacterial community has been studied with a polyphasic approach by comparing the rhizosphere of Bt maize cultivated in greenhouse with that of its non transgenic counterpart grown in the same conditions. In the two plants the bacterial counts of the copiotrophic, oligotrophic and sporeforming bacteria, and the community level catabolic ...

  • Control of Microthrix parvicella by aluminium salts addition

    Aluminium and iron chloride were added to a biological nutrient removal pilot plant (1,500 population equivalent) treating urban wastewater to investigate the control of Microthrix parvicella bulking and foaming by metallic salts. Monitoring plant performance over two 6-month periods showed a slight impact on the removal efficiencies. Addition of metallic salts (Me; aluminium or aluminium + ...

  • Interactions Between Yeasts and Grapevines: Filamentous Growth, Endopolygalacturonase and Phytopathogenicity of Colonizing Yeasts

    Abstract  It has been clearly established that phytopathogenic fungi, bacteria, and viruses exert biotic stresses on plants. Much less is known, however, about the interactions between enological species of yeast and their host plants. In a previous study, we described how Saccharomyces cerevisiae, the most common enological yeast, can act as a grapevine (Vitis vinifera L.) pathogen, ...


  • Release of transgenic bacterial inoculants - rhizobia as a case study

    The current debate on the release of genetically modified organisms to the environment must be informed by scientific data obtained from field studies. Many of the microorganisms that have potential applications outside the laboratory, especially in agriculture and horticulture, could be improved by genetic modification. Rhizobia, the bacteria that form N2-fixing symbioses with leguminous plants, ...

  • Innovation of the Month: Food Fermentation for Biopreservation

    Although the word “bacteria” is usually associated with sickness and disease, it is the driving force behind fermentation, a food process on which humans have relied for millennia. Some of the earliest recorded instances of fermentation come from East Asia where, according to William Shurtleff, founder of the ...

  • Poultry processing - Ammonia removal case study

    Background: A poultry plant in the South of England processes up to 100,000 birds per week. The company operates an Activated Sludge plant followed by a Rotating Biological Contactor the whole system being required to produce effluent ammonia of 20 mg/l. Whilst the treatment plant was able to reach this standard when it was first installed, the success of the company meant that more and more ...

  • The use of treated wastewater and fertigation in greenhouse pepper crop as affecting growth and fruit quality

    The performance and suitability of tertiary treated wastewater (TW) and/or fertigation (F) in pepper plants were studied over a 4-month period in greenhouse conditions. Four treatments were used consisting of (1) water, (2) water + F, (3) TW, and (4) TW + F. The F and/or TW application increased plant height and plant biomass compared with the control plants (irrigated with water) ...

  • Playing hide and seek below the soil

    Below the soil of a diverse grassland area you’ll find a jungle of plant roots. It is also home to a wide variety of bacteria and fungi, of which some are pathogenic and looking for a host in the tangle of roots. It appears that this is much more difficult when there is a larger diversity of plants as the host plant is more able to hide among the varied crowd. Greater plant diversity ...
