Microbial Culture Requires That Energy and All Components Needed for Cell Growth Be Provided. Media Components and Their Function (Complex and Defined Media). Carbon Sources Provide Energy, and Sometimes Provide Oxygen. Complex Media Have a Known Basic Composition but a Chemical Composition That is Not Completely Defined. Industrial Fermentation Broths May Have a High Initial Carbon (Sugar Content (Ethanol Fermentation Example). The Accumulation of Fermentation Products Is Proportional to Cell Mass In The Bioreactor. A Microbial Fermentation is Characterized by Distinct Phases of Growth. Expressions for Cell Growth Rate are Based on Doubling Time.

Glycolysis is the Oxidation of Glucose in the Absence of Oxygen. Oxidation Is Catalyzed by Oxidases In the Presence of O2, and by Dehydrogenases in the Absence of O2. A Membrane Bioreactor Couples Reduction and Oxidation Reactions (R-mandelic Acid Example). Three Stages of Catabolism Generate Energy, Intermediate Molecules and Waste Products. The Glycolysis Pathway Utilizes Glucose Both In the Presence (Aerobic and Absence of O2 (Anaerobic to Produce Pyruvate. Glycolysis Is Initiated By the Transfer of a High Energy Phosphate Group to Glucose. Products of Anaerobic Metabolism Are Secreted or Processed by Cells to Allow Continuous Metabolism of Glucose by Glycolysis. Other Metabolic Pathways That Utilize Glucose Under Anaerobic Conditions (Pentose Phosphate, Entner-Doudoroff, and Hexose Monophosphate Shunt Pathways). Knowledge of Anaerobic Metabolism Enables Calculation of Theoretical Yields of Products Derived From Glucose. Economics Favors the Glycolytic Pathway for Obtaining Oxygenated Chemicals from Renewable Resources. Citric Acid Cycle and Aerobic Metabolism. Respiration Is The Aerobic Oxidation of Glucose And Other Carbon-Food-Sources (Citric Acid Cycle). The Availability of Oxygen, Under Aerobic Conditions, Enables Microorganisms to Utilize Pyruvate Via the Citric Acid Cycle. The Citric Acid Cycle Generates Precursors for Biosynthesis of Amino Acids and Commercially Important Fermentation Products. Glucose Is Transformed to Commercially Valuable Products Via Fermentation Processes: A Summary. Essential Amino Acids Not Synthesized By Microorganisms Must Be Provided As Nutrients (Auxotrophs). The Utilization of Fats in Animals Occurs By a Different Mechanism than the TCA Cycle. Some Bacteria and Molds Can Grow on Hydrocarbons or Methanol in Aerated Fermentations (Single Cell Protein Case Study). Extremophiles: Microorganisms That Do Not Require Glucose, Utilize H2, and Grow At 80 to 100?C and 200 Atmospheres Have Industrial Uses.

Auxotrophs Are Nutritionally Deficient Microorganisms That Enhance Product Yields In Controlled Fermentations (Relief of Feedback Inhibition and Depression). Both Branched and Unbranched Pathways Cause Feedback Inhibition and Repression (Purine Nucleotide Example). The Accumulation of An End Metabolite of A Branched Pathway Requires A Different Strategy Than Accumulation of An Intermediate Metabolite. Amino Acids. The Formulation of Animal Feed Rations With Exogeneous Amino Acids Is A Major Market For Amino Acids. Microbial Strain Discovery, Mutation, Screening and Development Facilitated Introduction of Industrial, Aerated Fermentations for Amino Acid Production by C. glutamicum. Overproduction of Glutamate by C. Glutamicum Depends on An Increase in Bacterial Membrane Permeability (Biotin Deficient Mutant). A Threonine and Methionine Auxotroph of C. glutamicum Avoids Concerted Feedback Inhibition and Enables Industrial Lysine Fermentations. Cell (Protoplast Fusion Is A Method for Breeding Amino Acid Producers That Incorporate Superior Characteristics of Each Parent (Lysine Fermentation). Amino Acid Fermentations Represent Mature Technologies. Antibiotics. Secondary Metabolites Formed During Idiophase Are Subject to Catabolite Repression and Feedback Regulation (Penicillin and Streptomycin). The Production of Antibiotics Was Viewed as a Mature Field Until Antibiotic Resistant Bacteria Began to Appear. Bacteria Retain Antibiotic Resistance Even When Use of the Antibiotic Has Been Stopped For Thousands of Generations. Antibiotic Resistance Involves Many Genes (Vancomycin Example). Bibliography. Homework Problems. 12. GENETIC ENGINEERING: DNA, RNA, AND GENES. Introduction. DNA. DNA Is A Double Stranded Polymer of the Nucleotides: Thymine, Adenine, Cytosine and Guanine. The Information Contained in DNA Is Huge. Genes Are Nucleotide Sequences That Contain the Information Required for the Cell to Make Proteins. Transcription Is A Process Whereby Specific Regions of the DNA (Genes Serve As A Template to Synthesize Another Nucleotide, Ribonucleic Acid (RNA). Chromosomal DNA In A Prokaryote (Bacterium Is Anchored to The Cell?s Membrane While Plasmids are in the Cytoplasm. Chromosomal DNA In A Eukaryote (Yeast, Animal or Plant Cells Is Contained In The Nucleus. Microorganisms Carry Genes In Plasmids Consisting of Shorter Lengths of Circular, Extrachromosomal DNA. Restriction Enzymes Enable Directed In Vitro Cleavage of DNA. Different Type II Restriction Enzymes Give Different Patterns of Cleavage And Different Single Stranded Terminal Sequences. DNA Ligase Covalently Joins The Ends of DNA Fragments. DNA Fragments and Genes of Up To 150 Nucleotides Can Be Chemically Synthesized If The Nucleotide Sequence Has Been Previously Determined. Protein Sequences Can Be Deduced And Genes Synthesized Based On Complementary DNA Obtained From Messenger RNA. Selectable Markers Are Genes That Facilitate Identification of Transformed Cells That Contain Recombinant DNA. A Second Protein Fused to The Protein Product Is Needed To Protect The Product From Proteolysis (?-Gal-Somatostatin Fusion Protein Example). Recovery of Protein Product From Fusion Protein Requires Correct Selection of Amino Acid That Links The Two Proteins (Met Linker). Chemical Modification and Enzyme Hydrolysis Recovers An Active Molecule Containing Met Residues From A Fusion Protein (?-endorphin Example). Metabolic Engineering Differs From Genetic Engineering By the Nature of The End Product. Bibliography. Homework Problems. 13. METABOLIC ENGINEERING. Introduction. Building Blocks. L-Threonine Overproducing Strains of E. coli K-12. Genetically Altered Brevibacterium lactoferrin Has Yielded Improved Amino Acid Producing Strains.

DNA Sequencing is Based on Electrophoretic Separations of Defined DNA Fragments. Sequence Tagged Sites (STSs Determined From Complimentary DNA (cDNA Give Locations of Genes. Single Nucleotide Polymorphisms (SNPs Are Stable Mutations Distributed Throughout the Genome That Locate Genes More Efficiently Than STSs. Gene Chip Probe Array. Polymerase Chain Reaction (PCR). The Polymerase Chain Reaction Enables DNA to be Copied In Vitro. Thermally Tolerant DNA Polymerase From Thermus aquaticus Facilitated Automation of PCR. Only the 5’ Terminal Primer Sequence Is Needed To Amplify the DNA By PCR. The Sensitivity of PCR Can Be A Source of Significant Experimental Error. Applications of PCR Range From Obtaining Fragments of Human DNA For Sequencing To Detecting Genes Associated With Diseases. Conclusions. Bibliography. Homework Problems.
