polyethylene; in addition‚ their disposal as bio-waste makes them increasingly attractive in the pursuit of sustainable development (Queirós et al.‚ 2014). 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

One purpose of this paper is to show the importance of biology in our everyday life. The subject of this paper is the cause and affects of micro-organisms that are in the human digestive system. Article of choice‚ (Adnan‚ 2010) Benefits of Microorganisms to Humans‚ Retrieved February 8‚ 2013. This article was of interest because there are many bacteria that we encounter in our daily lives and it was informative to know that all bacteria is not bad. In fact‚ there needs to be a balance between the

Classification Why the butterfly belongs to the invertebrates: The first animals to evolve were invertebrates. Fossil evidence of invertebrates dates back to the late Precambrian‚ 600 million years ago. Invertebrates evolved from single-celled microorganisms. Since then‚ invertebrates have diversified into countless forms. An estimated 97 percent of all species are alive today are invertebrates. Invertebrates are united more by what they lack (a backbone) than by shared characteristics. Invertebrates
