essential oil of Lantana camara Linn were studied. The findings of the chemical study of essential oil of L. camara leaves revealed the presence of a high amount of sesquiterpenes and this oil remarkably inhibited the growth of most tested bacteria and fungi; Pseudomonas aeruginosa‚ Aspergillus niger‚ Fusarium solani and Candida albicans appearing as the most sensitive (Sousa et al.‚ 2012). Considerable research‚ such as this one‚ has focused primarily on the antibacterial properties the essential oil

microscopes‚ we use various methods to make microbes apparent. One of the most important methods is staining. Staining techniques play an essential role in the studying of microorganisms; they help to reveal characteristics of microbes‚ such as their morphologies‚ sizes‚ arrangements‚ chemical components and many more. The purposes of the experiments are to be familiar with each staining technique‚ to understand the differences between the techniques‚ to able to read results and to have the knowledge

to those fungi (Basidiomycota‚ Agaricomycetes) that have a stem (stipe)‚ a cap (pileus)‚ and gills (lamellae‚ sing. lamella) or pores on the underside of the cap. "Mushroom" describes a variety of gilled fungi‚ with or without stems‚ and the term is used even more generally‚ to describe both the fleshy fruiting bodies of some Ascomycota and the woody or leathery fruiting bodies of some Basidiomycota‚ depending upon the context of the word. Forms deviating from the standard morphology usually have

As mold and mildew are responsible for many health ailments‚ mold and mildew removal is a popular topic of discussion. Mold and mildew can be located indoors or outdoors‚ and they are fungi. While they do well in warm areas‚ they can survive in the cold as well. Molds reproduce by circulating seeds that can easily move around homes via wind‚ fans‚ an air conditioner‚ and more.

Unicellular organisms fall into two general categories: prokaryotic organisms and eukaryotic organisms.Unicellular organisms are believed to be the oldest form of life‚ possibly existing 3.8 billion years ago.[2] Prokaryotes‚ most protists‚ and some fungi are unicellular. Although some of these organisms live in colonies‚ they are still unicellular. These organisms live together
