a comparative study on growth rate and lipid content of various microalgae samples collected from biologically and geographically diversified areas on Nepal. Comparisons were also made on samples with same genus isolated from geographically diversified areas (i.e. high altitude (>4000 m) and mid hill (>1000 m))‚ and effect of seasonal variation (with respect to temperature) on similar species of microalgae. Euglena sp.‚ Chlorella vulgaris‚ and Scenedesmus sp. with growth rate of 0.401 day-1‚ 0

1900s to regulate the growth in batch culture of Saccharomyces cerevisiae18. Yeast producers observed that in the presence of high concentrations of malt‚ a by-product - ethanol - was produced‚ while in low concentrations of malt‚ the yeast growth was restricted. The problem was then solved by a controlled feeding regime‚ so that yeast growth remained substrate limited13. The concept was then extended to the production of other products‚ such as some enzymes‚ antibiotics‚ growth hormones‚ microbial

2. Why Choose Microalgae culture or Microalgae as an Ideal biomass? Or Microalgae: advantages and disadvantages The microalgae culture have the infinite potential to be used as primary producers of biomass in coming years‚ eventually they will turn out to be as most significant energy source. They can act as feedstock for several types of renewable fuels such as ethanol‚ methanol‚ biodiesel‚ methane and hydrogen. Table 1 represents certain feedstocks used for biofuel production (Chisti 2007; Dominguez-Faus

Study of Bacterial Growth and Resistance Level to Certain Antibiotics INTRODUCTION Escherichia coli—better known as E. coli—is a gram negative‚ rod shaped bacteria. It is relatively harmless‚ but can occasionally cause food poisoning. It can also provide Vitamin K2. It prevents the establishment of pathogenic bacteria‚ and is associated with or found in the intestinal organ. The antibiotic that E. coli is resistant to is Penicillin. Bacillus subtilis—better known as B. subtilis—is known as

The Effects of Antibiotics on Bacterial Growth Biology II 1996 Bacteria are the most common and ancient microorganisms on earth. Most bacteria are microscopic‚ measuring 1 micron in length. However‚ colonies of bacteria grown in a laboratory petri dish can be seen with the unaided eye. There are many divisions and classifications of bacteria that assist in identifying them. The first two types of bacteria are archaebacteria and eubacteria. Both groups have common ancestors dating to more

The identification of an unknown bacterial environmental isolate through a series of morphological‚ physiological and differential exercises. The purpose of the environmental isolate report is to learn what is necessary in order to take an unknown environmental isolate (EI) and identify it. This was achieved through a series of exercises that provided information on the morphological‚ physiological and biochemical traits of the EI which were then compiled and interpreted in order to make a presumptive

Experimental Hypothesis- Increasing the antibiotic concentration decreases bacterial growth. Scientific Theory Bacteria are prokaryotes and can be identified by their shape. Spherical bacteria are called cocci‚ rod shaped bacteria are called bacilli‚ spiral shaped bacteria are called spirilla and
