Point and Nonpoint Pollution Sources Point Sources Point-source pollutants in surface water and groundwater are usually found in a plume that has the highest concentrations of the pollutant nearest the source (such as the end of a pipe or an underground injection system) and diminishing concentrations farther away from the source. The various types of point-source pollutants found in waters are as varied as the types of business‚ industry‚ agricultural‚ and urban sources that produce them. Commercial

Polyhydroxyalkanoates comprise a class of polyesters of natural origin accumulated by a variety of microorganisms. These bioplastic compounds are intracellularly accumulated in the form of intracellular granules and stored in response to an environmental stress or nutrient limitation as a reserve of carbon‚ energy‚ and reducing power (Li et al.‚ 2014).

formulation is an essential stage in the design of fermentation process. Most fermentation media require liquid media‚ although some solid-substrate fermentations are also operated. Fermentation media must satisfy all the nutritional requirements of the microorganisms and fulfill the technical objectives of the process. There are several stages where media are required in a fermentation process; inoculum (starter culture)‚ propagation steps‚ pilot-scale fermentations and the main production fermentations. According

If life intelligent life in fact evolved from things as small as microorganisms‚ which many scientists have practically confirmed to exist in other planets‚ then why would those microorganisms not evolve into an intelligent form of life? With so many other planets with the same life supporting characteristics as Earth exist‚ there has to be at least one that will eventually make those microorganisms evolve into an intelligent form of life. Besides‚ it would be very hard to assume
