    staining techniques and biochemical testing to identify an unknown bacteria using Bergey’s manual. Bergey’s manual of Systematic Bacteriology is a dichotomous key primarily used to identify a bacterial species. Biochemical tests are used to differentiate different species of bacteria. These tests are effective in determining the characteristics of the microbe being tested. Such characteristics include citrate utilization‚ gelatin hydrolysis‚ nitrate reduction‚ etc. Biochemical testing is very important

    Soft engineering works in harmony with the natural environment and is effective in protecting the coast. To what extent do you agree with this view? I agree with this view to a great extent. Soft engineering methods are natural ways of dealing with erosion‚ however‚ every method comes with disadvantages. One way in which soft engineering working well with the natural environment and is also effective‚ is beach nourishment. This is where materials such as sand and shingle are moved from the bed

    Biochemistry Exam I Terminology Boiling point is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid. At this temperature the liquid phase changes into the gaseous phase (also a colligative property) Melting point is the temperature at which the solid and liquid phases are in equilibrium. At this temperature the solid state changes into a liquid phase (also a colligative property) Specific heat is the amount of energy (in joules or calories) needed

    Since all natural waterways contain bacteria and nutrients‚ almost any waste compounds introduced into such waterways will initiate biochemical reactions (such as shown above). Those biochemical reactions create what is measured in the laboratory as the Biochemical oxygen demand (BOD). Such chemicals are also liable to be broken down using strong oxidizing agents and these chemical reactions create what is measured in the laboratory as the Chemical oxygen demand (COD). Both the BOD and COD tests

    CHAPTER 1 INTRODUCTION 1.1 Background of the Study Generally‚ Palm oil mill effluent (POME) contains high chemical oxygen demand (COD) and biochemical oxygen demand (BOD) which can pollute the environment ecosystem if it is not treated properly. The characteristics of fresh POME are that it is highly viscous liquid‚ brownish in colour and discharged at a temperature of 80-90oC. Moreover‚ POME is extremely poisonous with a very low pH between 3.5 and 4.2‚ high chemical and biological oxygen demand
