Factors influencing the abundance, community composition and activity states of bacterioplankton from the tidal freshwater James River
… the tidal-freshwater James River, variation in bacterial abundance was linked to nutrient availability and autochthonous production with highest bacterial densities associated with low-nutrient, high-chlorophyll a conditions. Laboratory experiments revealed that bacterial growth rates were …

Comparison of optical density, total cell protein, and number of viable cells (via fluorescent straining) as measures of microbial growth kinetics in suspended and biofilm cultures during biodegradation of naphthalene
Most studies on bacterial growth kinetics have been dependent on theoretical modeling with general biomass measurements using either dry weight or optical density (OD), without distinguishing live from dead bacteria or debris. As a result, there remains considerable uncertainty in reliably …

Passive transport through biological membranes
… significant molecules like for example the bacterial signal indole. Indole is an organic compound linked to important cellular processes like bacterial growth rates and cellular morphology. It is believed that indole is actively transported through the membrane of Escherichia coli via influx …

Freshwater inflows to estuaries : organic carbon and microbial food webs in south-east Australia
… of DOC increased during FWI events, and in turn bacterial growth rates were also higher during and immediately following inflow events. Bacterial growth was carbon limited most of the time, though during high flows, bacteria often became phosphorus limited. Changing availability of DOC and …

Effects Of Environmental Factors On Anaerobic Granular Sludge In Upflow Anaerobic Sludge Blanket Reactors
… sufficient amount of these elements for the bacterial metabolism, and excellent COD digestion rates could be maintained in the reactors. Yeast extract showed a strong positive effect on the bacterial growth rate, but had no significant contribution to the specific activity of bacteria.;The …

Evaluation of ligninolytic enzymes of (coptotermes curvignathus) gut bacteria for oil palm residues biodelignification
… in kraft lignin-induced media was expressed. Bacterial growth rates were determined by measuring OD600 of grown cultures, while the LDE activity was determined using specific substrates. Chemical characterizations (Hollocellulose, cellulose, hemicellulose and lignin) of the oil palm residues …

Factors controlling bacterial abundance, biomass and growth at the Bermuda Atlantic time-series site
… environment to study the factors controlling bacterial growth dynamics. The region was sampled at monthly intervals from 1991 to 1996. A typical annual cycle was defined by a deep winter mixing, followed by an increasing stratification of the mixed layer through summer and fall. There were …
