Phage breeding was employed to produce a bacteriophage (Listeria monocytogenes phage ATCC 23074-B1) which was specific for L-forms of L. monocytogenes. The bred phage was compared to its unbred parent for lytic activity and specificity. It was also tested for its ability to prevent L-form biofilm formation on stainless steel and compared with an organic acid (lactic) at L-form biofilm inactivat...

In a study of intergroup reactions, four virulent Group A streptococcal phages were found to form plaques in high titer on lawns prepared from a number of Group C streptococcal strains. Whether the phages were propagated on the homologous (Group A) strain or a heterologous (Group C) strain did not appear to influence consistently the plaque-forming efficiency on lawns prepared from a homologous...

Peatlands are important sinks for atmospheric carbon (C), yet the role of plant functional types (PFTs) for C sequestration under climatic perturbations is still unclear. A plant-removal experiment was used to study the importance of vascular PFTs for the net ecosystem CO2 exchange (NEE) during (i.e., resistance) and after (i.e., recovery) an experimental drought. The removal of PFTs caused a d...

Sources and mechanisms of nutrient transport in lawn irrigation driven surface runoff are largely unknown. We investigated the transport of nitrogen (N) and phosphorus (P) in lawn irrigation driven surface runoff from a residential neighborhood (28 ha) of 56% impervious and 44% pervious areas. Pervious areas encompassing turfgrass (lawns) in the neighborhood were irrigated with the reclaimed wa...

SCANTURF is a joint Nordic programme for turfgrass variety testing, set up in 2005 and funded by entrance fees only. It replaced simplified the former government-funded national evaluation programmes Finland, Sweden, Denmark Norway. The includes testing of all cool-season grasses on lawn/fairways at 15–20 mm mowing height (“lawn trials”) optional Poa pratensis L. Lolium perenne simulated footba...

Bacteriophages induced by mitomycin treatment of Erwinia chrysanthemi KS612 produced plaques on lawns of E. chrysanthemi EC183 and KS605. Bacteriophage Erch-12, purified from one such plaque, transferred an array of chromosomal genes (arg, leu, his, ser, thr, trp, ura) to appropriate recipient strains derived from E. chrysanthemi EC 183. Recombinants were formed in the absence of cellular conta...
