|Abstract:||<smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="State" downloadurl="http://www.5iamas-microsoft-com:office:smarttags"><smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place" downloadurl="http://www.5iantlavalamp.com/"> In the present study,<b style=""> </b>16 fungal species were recorded in the rhizosphere of 4 terrestrial species [<i style="">Acacia farnesiana</i> (Linn.) Willd, <i style="">A. leucophloea</i> (Robx.) Willd, <i style="">A. nilotica</i> (Linn.) Del. and <i style="">A. raddiana</i> Savi] and 4 marshy species (<i>Arundo donax</i> Linn., <i>Phragmites karka</i> Steud, <i>Typha angustata</i> Bory & Chaub and <i>Scirpus tuberosus</i> Derf.) grown in tap water (control) and spent wash treatments (COD = 750-12,000 ppm). Their species richness was relatively higher (2-folds) in the spent wash treatments than their respective controls while their colony forming units were almost similar, exceeding in number to more than 300 units for a particular fungal species in the community. <i style="">Aspergillus</i> was the most dominant genus (4 species) followed by <i>Fusarium</i> (2 species) while the remaining 10 genera had one species each. The bacteria were Gram (+) bacilli and cocci arranged singly and in chains (also in bunches in cocci). In comparison to control, their CFU values were significantly higher (2-10-folds) in spent wash treatments, especially in the rhizosphere of marshy species. </smarttagtype></smarttagtype>|
