“…It did not occur at each station at the same time during the year and was not collected in the second year of the study. These data contradict those reported by Borut and Johnson (1962), who found no distributional patterns for 142 fungal species from sediments in the water of the Neuse-Newport Estuary along a salinity gradient of 0.0-36.3 %0 and Johnson (1967), who reported that during a seven-year study of the same estuary, 12 % of the wood-inhabiting fungi collected were found throughout the estuary from 0-32 %c salinity.…”

The effects of changes in salinity and temperature on the distribution of wood-inhabiting Ascomycetes and Fungi Imperfecti in the Patuxent River were studied. Forty-one species of Ascomycetes and 83 species of Fungi Imperfecti were collected; Pyrenomycetes and dernatiaceous Hyphomycetes predominated. Salinity was' the most important factor affecting the distribution of fungi, and the major change in species composition occurred where freshwater and saltwater mix. The ratio of Ascomycetes to Fungi Imperfecti increased with increasing salinity, while the number of species collected generally decreased. Triadelphia lieterospora Shearer and Crane was collected only at low temperatures and appears to be the only regularly occurring species whose distribution was affected by temperature. The interaction of temperature and salinity did not affect the distribution of four species that occurred regularly at wide ranges of temperature and salinity. Species composition differed between two Iimnetic stations, one above and the other below the discharge points of two sewage treatment plants.

“…The capacity of the latter bacterium to grow and metabolize glucose but not DCP in sterile lake water, except if the DCP-containing samples received supplemental nutrients, possibly results from the presence of inhibitors whose actions are reversed by the nutrients or from the need for additional nutrients for the metabolism of DCP but not glucose. The presence of antimicrobial agents in natural waters has been described (4,17), and Gispen and Gan (8) reported that filterable, heat-labile inhibitors of Shigella sp. and Salmonella sp.…”

Pseudomonas strains capable of mineralizing 2,4-dichlorophenol (DCP) and p-nitrophenol (PNP) in culture media were isolated from soil. One DCP-metabolizing strain mineralized 1.0 and 10 ,ug of DCP but not 2.0 to 300 ng/ml in culture. When added to lake water containing 10 ,ug of DCP per ml, the bacterium did not mineralize the compound, and only after 6 days did it cause the degradation of 1.0 jig of DCP per ml. The organism did not grow or metabolize DCP when inoculated into sterile lake water, but it multiplied in sterile lake water amended with glucose or with DCP and supplemental nutrients. Its population density declined and

“…An estuary is under the influence of marine conditions such as tides, waves, influx of saline water, as well as the flow of fresh water and sediment of the river (Manoharachary et al, 2005). Studies on the mycobiota in estuarine ecosystems have focused on the diversity or metabolic activities of fungi from estuarine waters, sediments, wood and litter, marshes and mangroves (Borut and Johnson, 1962;Shearer, 1972;Cooke and Lacourse, 1975;Rai and Chowdhery, 1978;D'souza et al, 1979;Maria and Sridhar, 2002;da Silva et al, 2003;Tsui and Hyde, 2004;Anita et al, 2009;Karamchand et al, 2009;Nambiar and Raveendran, 2009;Rani and Panneerselvam, 2009;Pearman et al, 2010;Mohamed and Martiny, 2011). The halophilic nature of these fungi has not been described.…”

Halophilic mycobiota was isolated from Mandovi estuary and it was dominated by Aspergillus and Penicillium species. Cladosporium and Eurotium were found in lesser numbers while obligate halophiles were found only amongst the aspergilla and they were all identified as Aspergillus penicillioides. Some aspergilli and all the isolates of Penicillium, Cladosporium and Eurotium were facultative halophiles. There were significant differences in growth of each isolate at different salt concentrations. Most of the isolates were euryhaline, having a wide range of salt tolerance; a few were stenohaline, with a narrow range of halotolerance. The isolates were mainly moderate halophiles, with a very few slight halophiles. Isolation of obligate halophilic fungi from polyhaline environment of an estuary is hereby reported for the first time.
