“…Previous reports have suggested that in acid soils favouring fungi (Bardgett et al 1996) acidophilic actinomycetes of the genus Streptomyces tend to dominate (Zakalyukina et al 2002). This is significant since many soil actinomycetes have been shown to lyse or inhibit soil fungi (Williams et al 1976;Oyarzuna et al 1998;ElTarabily et al 2000;Zaitlin et al 2004;El-Tarabily and Sivasithamparamb 2006) or to generally reduce soil fungal populations (Crawford et al 1993;El-Tarabily et al 2000). This ability to inhibit fungi may be related to chitinase production (De Boer et al 1998;Gomes et al 2000) or to the production of specific antifungal compounds (Frändberg et al 2000).…”

“…The use of organic inputs in the form of farm yard manure (FYM) and composts are considered to be important in increasing microbial diversity and enhancing nutrient cycles in soils (Mader et al 2002) with some reporting that microbial diversity is enhanced by organic agriculture (Hole et al 2005). However, the real extent to which organic and inorganic fertilisers 'enhance' the diversity of different functional and taxonomic groups in soils remains largely unexplored (Zaitlin et al 2004). …”

Palace Leas, a long-term experiment at Cockle Park Farm, Northumberland, UK was established in winter 1896-1897 since when the 13 plots have received regular and virtually unchanged mineral fertiliser and farm yard manure inputs. Fertilisers have had a profound impact on soil pH with the organically fertilised plots showing a significantly higher pH than those receiving mineral fertiliser where ammonium sulphate has led to soil acidification. Here, we investigate the impact of organic and mineral fertilisers on the actinobacterial community structure of these soils using terminal restriction fragment length polymorphism (T-RFLP) and 16S rRNA gene analysis. To differentiate fertiliser effects from seasonal variation, soils were sampled three times over one growing season between May and September 2004 and January 2005. Community profiles obtained using T-RFLP were analysed using multivariate statistics to investigate the relationship between community structure, seasonality and fertiliser management. Soil pH was shown to be the most significant edaphic factor influencing actinobacterial communities. Canonical correspondence analysis, used to investigate the relationship between the 16S rRNA gene community profiles and the environmental parameters, showed that actinobacterial communities also responded to soil water content with major changes evident over the summer months between May and September. Quantitative PCR of the actinobacterial and fungal 16S and 18S rRNA genes, respectively suggested that fungal rRNA gene copy numbers were negatively correlated (P = 0.0131) with increasing actinobacterial signals. A similar relationship (P = 0.000365) was also evident when fatty acid methyl esters indicative of actinobacterial biomass (10-methyloctadecanoic acid) were compared with the amounts of fungal octadecadienoic acid (18:2omega9,12). These results show clearly that soil pH is a major driver of change in actinobacterial communities and that genera such as Arthrobacter and Micrococcus are particularly abundant in soils receiving organic inputs whilst others such as Streptomyces, Acidimicrobium and Actinospica are more prevalent in acid soils. The importance of these findings in terms of fungal abundance and potential disease suppression are discussed.

“…Samples were taken from the top layer of soil (100 mm depth) and passed through a 2 mm sieve. Samples were homogenized and dried in the thin layer (10 mm) for 24 hours at the room temperature (Zaitlin et al, 2004). Analyses were performed in three replications and average values are presented.…”

“…The presence of actinomycetes, mainly of the genera Streptomyces, Nocardia and Nocardiform, has been detected in sediment and seawater in marine ecosystems (Sharma & Pant 2001, Remya & Vijayakumar 2008, Jiang et al 2009). Actinomycetes play a major role in the recycling of organic matter and contribute significantly to the turnover of complex biopolymers, such as lignocellulose, hemicellulose, lignin, pectin, chitin, keratin, crude oil and hydrocarbons (Suzuki et al 1994, Sharma & Pant 2001, Zaitlin et al 2004, Vijayakumur et al 2007, Reyma & Vijayakumur 2008. Actinomycetes are a well-known, major source for production of antibiotics and are the strongest antagonists among microorganisms (Jensen et al 2005, Baltz 2008, Vimal et al 2009).…”

The abundance of actinomycetes, filamentous fungi and yeasts in the marine epipsammon habitat and their spatial distribution were studied with conventional plating techniques in two marine beaches (Ustka and Czołpino, southern Baltic Sea) which are characterized by different anthropic pressure levels. Actinomycetes constituted the predominant group of studied microorganisms, while the least numerous were yeasts in the sand of both studied beaches. On both of the beaches researched in this study, the amounts of accumulated actinomycetales, fungi and yeasts were similar. When analyzing the distribution of the microflora along the horizontal beach profiles we found significant differences. In the sand collected along the profile perpendicular to the shoreline in Ustka and Czołpino beaches, the highest numbers of actinomycetes, filamentous fungi and yeasts were noted in the samples from the dune and the lowest in those from the subtidal zone and waterline. Generally, higher numbers of studied microorganisms were observed in the surface * Corresponding author e-mail: pperlinski@apsl.edu.pl than in the subsurface sand layer. The occurrence of actinomycetes, filamentous fungi and yeasts showed considerable seasonal variation.
