Bacterial responses to temperature and substrate concentration during the Newfoundland spring bloom
We postulate that microbial metabolism and production in cold waters are hmited by the ability of bacteria to transport and/or assimilate substrates at the low concentrations usually present. We measured rates of microbial activity in the water colunln and benthos in Conception Bay, Newfoundland and adjacent coastal waters, during 3 spring blooms. Chlorophyll abundance and distribution, photosy...
متن کاملBacterial DMSP metabolism during the senescence of the spring diatom bloom in the Northwest Atlantic
The impact of the decline of the vernal bloom on the bacterial metabolism of dimethylsulfoniopropionate (DMSP), the precursor of dimethylsulfide (DMS), was investigated during a 7 d Lagrangian study conducted in the Northwest Atlantic in spring 2003. Daily variations in bacterial leucine incorporation, dissolved DMSP (DMSPd) uptake and DMS production rates were measured in the surface mixed lay...
متن کاملconsequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
Succession and diel transcriptional response of the glycolate-utilizing component of the bacterial community during a spring phytoplankton bloom.
The influence of the phytoplankton-specific organic compound glycolate on bacterial community structure was examined during the 2004 spring phytoplankton bloom (February to April) in Dabob Bay in Washington. The diversity of the bacteria able to utilize glycolate during the phytoplankton bloom was determined using previously developed PCR primers to amplify the gene for the D subunit of glycola...
متن کاملBacterial responses to environmental herbicide pollutants (glyphosate and paraquat)
The toxic effect of herbicides on non- target microorganisms may influence degradation of organic matter resulting in changes to nutrient cycling. In the present study, different strains of bacteria incubated in media containing different concentrations of glyphosate and paraquat were assessed over a period of two incubation terms. The deleterious impact of the herbicide was observed as glyphos...
