“…These microorganisms are able to degrade cellulose and hemicelluloses as they oxidize and solubilize the lignin component. Several works reported dominance of streptomycetes population in wetlands constructed for industrial waste water treatment (Shatoury et al 2004), however no systematic study has been carried out to account for the diversity of Streptomyces specifically in arable soils facing paper mill effluents over a long period. Therefore, the aim of present study was to determine the effect of irrigating sugarcane crop with the water from local channel mixed with paper mill effluent from Century paper mill (CPM), Lal Kuan, Uttrakhand, India, on culturable as well as unculturable streptomycetes community.…”

Irrigation of farm field with water mixed with pulp and paper mill effluent from Century pulp and paper mill in Uttrakhand state of India for over last 25 years in succession increased streptomycetes population (120 9 10 5 ) compared to the fresh water irrigated fields (48 9 10 3 in WIF). Denaturing gradient gel electrophoresis, amplified ribosomal DNA restriction analysis, 16S rRNA gene sequencing, BIOLOG TM substrate usage, production of extracellular enzymes (xylanase and cellulase) and plant growth promoting attributes were applied to monitor changes in genetic and metabolic diversity of streptomycetes. Significant variation was observed for production of extracellular enzymes, Indolic compounds, siderophore and P-solubilisation among isolates. Metabolic substrate usage of Streptomyces isolates was evaluated using the BIOLOG TM GP2 plates and unique carbon substrate usage profiles were observed. Based on 16S rRNA gene sequencing, the isolates were identified as Streptomyces variabilis, Streptomyces spp.

“…Nevertheless, there are only few studies that describe the role of actinobacteria in CW systems. Hatano et al (1994) and El-Shatoury et al (2004) investigated actinomycetes diversity and role in CW. Hatano et al (1994) reported that the majority of actinobacteria isolates from pulp-mill wastewater treated by CW were identified as the genus: Streptomyces.…”

Additionally, El-Shatoury et al (2004) showed that biofilm-attached actinomycetes reflect successful competition with other microorganisms based on their biodiversity.…”

In the present study, Streptomyces sp. CW1 was isolated from a constructed wetland system mesocosm and identified as such based on 16S rDNA analysis, and additional biochemical properties were evaluated. This isolate was found to be halotolerant (up to 11% NaCl) and able to grow and utilize biopolymers such as: agarose, agar, gellan gum (a bacterial polysaccharide), polypectate and chitin as the sole carbon and energy source. Since the primary isolation was performed based on its capability to degrade phenol, the high cell yield coefficient showed rapid growth on phenol (0.82-0.98 mg dry biomass/mg phenol). Its halotolerance and the capability to biodegrade biopolymers found mainly in the marine environments, suggest on its primordial oceanic origin. In the present study some of its characteristics are described and discussed along with its beneficial use for wastewater purification processes in constructed wetland systems.

“…The results obtained are in line with those reported in the literature. Indeed, the Streptomyces family is the most common among the actinomycete isolates from water(Zaitlin and Watson 2006), polluted water habitats (Naidenova and Vladimirova 2002) and from constructed wetland for industrial effluent treatment(El-Shatoury et al 2004).…”

One hundred twenty-two different actinomycete strains were isolated from sample collected from several depths of the Marrakech wastewater infiltration-percolation system. To evaluate the antimicrobial effect of the different actinomycetes recovered, eleven wastewater-associated micro-organisms known as human potential pathogens were used. Results showed that 44 isolates had an in vitro inhibitory effect toward at least seven of the indicator microorganisms while only five active strains inhibited all these pathogens. All five selected active isolates belonged to the genus Streptomyces. Three were identified as Streptomyces violaceorubidus. These isolates showed the broad activity spectrum against a wastewater-associated pathogenic yeast (Candida albicans), Gram-negative (Salmonella sp. CCMM B 17 ) and Gram-positive (Staphylococcus aureus CCMM B 3 ). These findings indicate the potential involvement of antagonistic actinomycetes in the removal of wastewaterassociated pathogens.
