Cyanobacteria

Fortunately, due to this symbiotic union, the first plant was born with the ability to perform photosynthesis. However, in order for a symbiotic union to occur, there has to be some sort of cooperation from the parties involved. So how did the cyanobacteria give the alga the ability to photosynthesize? Well, due to the bacterium being infected with a parasite, the parasite gave the bacterium the ability to transfer food from the chloroplasts to the alga through the exchange of genes. However,…

The very fast death factor is a very potent weapon that has still not been addressed. We stand as the voice of the people and demand to add Anatoxin-a (C10H12NO) to the banned chemicals list. Anatoxin-a targets the nervous system thus making it virtually impossible to stop it since it targets the body in a matter of moments. One gram of this chemical can kill 350 people and unlike many other poisons this chemical works fast to kill. Even before the eventual death by respiratory paralysis that…

The Catchment Land Use for Environmental Sustainability model (CLUES), designed by the National Institute of Water and Atmospheric Research Ltd (NIWA), provided the data for both the Nitrogen and the Phosphorus concentrations throughout New Zealand. The development of CLUES was through a consolidation of existing mapping procedures and modelling(EnviroLink, 2012), and contributed to by various research organisations (NIWA, 2016). From this collaboration, the models responsible for the Nitrogen…

resulting in a lot of change. Our chlorophyll a content was 18.26 ug/L (table 1 in the appendices). Furthermore, the abundance of phytoplankton sampled from Ada Hayden supports our prediction (Table 3 and Figure 3, in appendices). We found more cyanobacteria and green algae which are more commonly found in mesotrophic lakes (Claustre 1994). The results of our…

There has been very limited research conducted on the cyanotoxins and cyanobacteria produced bioactive compounds. The important research areas are- (a) Modeling tools for predicting and preventing harmful algae blooms, which include all environmental and anthropogenic factors to predict and prevent algae blooms, (b) Mitigation…

ecology of countless species. Endosymbionts and their hosts typically represent distinct domains of life. The origin of primary plastid is traced back to a single primary endosymbiosis where a non-photosynthetic protist engulfs a photosynthetic cyanobacteria as cytoplasmic organelles. Plastids and the mitochondria are organelles in eukaryotic cells that derived from bacterial endosymbionts through the invasion and enslavement of synergistic amalgamation. The descendants of the primitive…

Discovering Microbes In A Mini Ecosystem Introduction: Every ecological environment provides with distinct nutrients that allows certain microorganism to survive and grow. Sergei Winogradsky, a Russian microbiologist, developed the Winogradsky Column to grow and investigate microorganisms in a complex biofilm communities. This column will grow different microbes at different gradients that will appear on the column. Depending on the various concentrations of nutrients, choice of soil and water…

streams and into the sea, which in turn encourages algae and most, if not all, aquatic plants to overgrow. Fishes will then suffocate due to lack of oxygen and sunlight excessively consumed by algae and aquatic plants. According to Dodds et al, cyanobacteria blooms, contaminated supplies of drinking water, and hypoxia are the known consequences of eutrophication. Chislock, M. F., Doster, E., Zitomer, R. A. & Wilson, A. E. (2013) quoted Lehtiniemi et al (2005), in their article: Eutrophication:…

through microbiology that the existence of lead to the discovery of microorganisms, and with this discovery there was a lot of changes to everyday life. IMPORTANCE IN HUMAN LIFE Photosynthesis was able to take place because of Cyanobacteria. This was because Cyanobacteria obtain its energy through photosynthesis. Photosynthesis is important to human life because of the byproduct of the process which is oxygen. Oxygen is vital to humans as it allows humans and animals to carry out processes in…

evolutionary processes. The production of the majority of oxygen on Earth can be attributed directly and indirectly to these microorganisms. Photosynthesis was "co-opted from a precocious and ancient form of life known as cyanobacteria" (Kasting and Siefert 2002, p.1066). Cyanobacteria provided oxygen to the Earth's atmosphere along with nitrogen in the Earth's oceans (Kasting and Siefert 2002). Thus the evolution of the Earth's atmosphere is linked to the development of oxygen through…
