    Advanced Biology
    (Skyfox Publishing Group, 2020) Ramasamy, Sakthivel
    A cell is the structural and fundamental unit of life. The study of cells from its basic structure to the functions of every cell organelle is called Cell Biology. Robert Hooke was the first Biologist who discovered cells. All organisms are made up of cells. They may be made up of a single cell (unicellular), or many cells (multicellular). Mycoplasmas are the smallest known cells. Cells are the building blocks of all living beings. They provide structure to the body and convert the nutrients taken from the food into energy. Cells are complex, and their components perform various functions in an organism. They are of different shapes and sizes, pretty much like bricks of the buildings. Our body is made up of cells of different shapes and sizes. Cells are the lowest level of organisation in every life form. From organism to organism, the count of cells may vary. Humans have the number of cells compared to that of bacteria. Cells comprise several cell organelles that perform specialised functions to carry out life processes. Every organelle has a specific structure. The hereditary material of the organisms is also present in the cells.

    Enumeration of Total Coliform Faecel Bacteria at two different Fish Landing Centres of Tuticorin
    (European Journal of Biomedical and Pharmaceutical Sciences, 2016) Ramasamy, Sakthivel
    The present investigation was aimed to explore the total coliform, Streptococcus aureus and faecel Streptococcus counts of the sea water from two selected fish landing stations of Tuticorin viz., Thirespuram and Sinthathirai matha kovil areas during 2007-2008. Formation of coliforms are analysed by standard procedure of MPN (Oblinger and Koburger, 1975) and IMVIC test (Poers and Latt, 1977). Enumeration of faecel coliform was detected by membrane filter technique (Bernasoni et al., 2006). The faecel streptococcal screening was carried out using multiple tube dilution method explained by Grasso et al., (2000). The results of two studied stations revealed that, station 2 encountered maximum Streptococcus aureus and faecel Streptococcus count in sea water [1400 MPN/100ml]. At station 1 and 2, maximum coliform count in sea water is 1600 MPN / 100 ml. The sediment samples at station 2 showed maximum total coliform counts [50 cfu / g]. The flesh of fin fish sample also showed invariably higher total coliform and fecal Streptococcus counts at station 2. The total coliform count of fish sample at both stations is recorded above the maximum permissible limit [5200 cfu /g]. Station 1 showed maximum Streptococcous aureus count in fish sample. Of the 2 stations studied, station 2 Sinthathirai matha kovil recorded maximum total coliform and faecel bacteria counts in water than the other station. Thus the results of present study is a preliminary account and it clearly indicates that a systematic study at these two important landing centres viz., Thirespuram and Sinthathirai matha kovil areas over the period of time during 2007-2008.

    Organic Liquid Detegent Formulation and its Biodegradability Potential – An Evaluation
    (Journal of Fundamental & Comparative Research, 2022) Ramasamy, Sakthivel
    Huge quantities of water are wasted due to poor management of the water system by humans. Water is used in two different ways, consumptive use and non-consumptive use. Depletion of energy reserves, ecosystem health, water security and other sustainability challenges are undermined behind wasting the water. Hence there is a threat to the freshwater resources all over the world in both developed and developing countries. It is also recorded that numerous strategies have been adopted to reduce, recycle and reuse the freshwater so as a conserved sustainable utility (Stanley et al., 2012). It is also recorded that an estimated 1 billion lack access to drinking water and 2.7 billion people lack access to sanitation (Varosmarthyet al., 2011). Both in developed and developing countries overlapping challenges are felt with reference to the freshwater management biodiversity (WHO 2008). The study involving the formulation of an organic liquid detergent was carried out in accordance with the standard protocol. Realising the need for effective conservation, the paper aims at encouraging people to adopt a cost-effective product that will be eco-friendly and inert the water conservation for future and present generations.

    Phycoremediation of Industrial Effluent from Tannary in Peranampattu and Ambur area of Palar River
    (European Journal of Biomedical and Pharmaceutical Sciences, 2016) Ramasamy, Sakthivel
    The leather industry represents an important economic sector in many countries. On the other hand, it generates large amounts of wastewater containing ammonium ion, sulphides, surfactants, acids, dyes, sulfonated oils and organic substances including natural or synthetic tannins agents. Tannery wastewater treatment is very complex, due to the addition of large number of chemicals in several concentrations. The treatments of these effluents using physical - chemical methods alone are quite expensive technologies. Hence the present work is focused on biological treatment to reduce the pollutants of tannery effluents and through micro algal treatment process taken from the tannery industries Peranampattuand AmburPalar River effluents, Tamil Nadu, India. The effluent samples were characterized by measurements of Physico – chemical properties, such as, BOD, COD, etc.,. In our findings we observed that the consortium of Microalgal species such as Chlorella vulgaris andScenedesmusdimorphusat various ratios (Control, 100:400, 200:300, 250:250, 300:200, 400:100 of algae and effluent concentration respectively) effectively reduces the TDS, COD and BOD level of effluents which was confirmed by the Physico-Chemical measurements at regular interval of 7 days for a period of 21 days. The concentration of algal consortium and effluent 250:250 was found to effectively reduce TDS, BOD and COD levels when compared to individuals. Hence this technology avoids use of chemicals and the whole process of effluent treatment is simplified to make it and eco-friendly & economical.

    Plant Biotechnology
    (Skyfox Publishing Group, 2020) Ramasamy, Sakthivel
    An important aspect of all biotechnology processes is the culture of either the plants cells or animal cells or microorganisms (Fig. 1). The cells in culture can be used for recombinant DNA technology, genetic manipulations etc. Plant cell culture or the plant tissue culture is based on the unique property of the cell-totipotency. The concept of modern plant biotechnology originated in the year 1838, from the Cell theory of Schleiden and Schwann, which emphasises cell as the primary unit of all living things. In 1902, the concept of totipotency (The ability of a single cell to divide and produce all of the differentiated cells in an organism) was put forth by Galberlandt citing the production of somatic embryos from vegetative cells. From then on with leaping steps of technology growth Biotechnology hadstrodeahead. Plant biotechnology has succeeded in development of transgenic plant which has now become the nodal point for many applications for plant biotechnology.
