Bacteria have also been enlisted in the fight against hunger: certain bacteria and fungi are cultivated on aliphatic hydrocarbon substrates buy cheap zocor 40mg on-line cholesterol qualitative test, which supplycarbon and energy zocor 10 mg amex cholesterol levels in kerala, then harvested and processed into a protein powder (single cell protein). Culturing of bacteria in nutrient mediums based on methanol is another approach being used to pro- duce biomass. One form such control activity takes is regulation of the activities of existing enzymes. Many enzymes are allosteric proteins that can be inhibited or activated by the final products of metabolic pathways. One highly economical type of regulation controls the synthesis of 3 enzymes at the genetic transcription or translation level (see the section on the molecular basis of bacterial genetics (p. Growth and Culturing of Bacteria Nutrients The term bacterial culture refers to proliferation of bacteria with a suitable nutrient substrate. Other necessities include sources of carbon and nitrogen for synthesis of specific bacterial compounds as well as minerals such as sul- fur, phosphorus, calcium, magnesium, and trace elements as enzyme activa- tors. Nutrient agar liquefies when heated to 1008C and does not return to the gel state until cooled to 458C. Selective mediums Contain inhibitor substances that allow only certain bacteria to proliferate. The Physiology of Metabolism and Growth in Bacteria 165 Growth and Cell Death Bacteria reproduce asexually by means of simple transverse binary fission. The time required for a reproduction cycle (G) is called the generation time (g) and can vary greatly from species to species. Fast-growing bacteria cultivated in vitro have a gen- eration time of 15–30 minutes. Obligate anaerobes grow much more slowly than aerobes; this is true in vitro as well. Of course the generation time also depends on the nutrient con- tent of the medium. The so-called normal growth curve for bacteria is obtained by inoculat- ing a nutrient broth with bacteria the metabolism of which is initially quies- cent, counting them at intervals and entering the results in a semilog coor- dinate system (Fig. The lag phase (A) is characterized by an increase in bacterial mass per unit of volume, but no increase in cell count. During this phase, the metabolism of the bacteria adapts to the conditions of the nutrient medium. In the following log (or exponential) phase (C), the cell count in- creases logarithmically up to about 109/ml. This is followed by growth decel- eration and transition to the stationary phase (E) due to exhaustion of the nutrients and the increasing concentration of toxic metabolites. The generation time can only be determined dur- ing phase C, either graphically or by determining the cell count (n) at two different times and applying the formula: t2 À t1 g ¼ : log2 n2 À log2 n1 Normal Growth Curve of a Bacterial Culture Fig. F A B (Hours) Time (Days) Kayser, Medical Microbiology © 2005 Thieme All rights reserved. The number of living cells in a given culture or material can be determined by means of the colony counting method. Using the pour platetechnique, each dilution is mixed with 1 ml of liquid agar and poured out in a plate. The simplest way to determine the mass is by means of photometric ad- sorption measurement. The increases in mass and cell count run parallel during phase C on the growth curve. The Molecular Basis of Bacterial Genetics & Bacteria possess two genetic structures: the chromosome and the plas- mid. Noncoding interposed sequences (introns), like those seen in eukaryotes, are the excep- tion. The phases of transcrip- tion are promoter recognition, elongation, and termination. Many genes that code for functionally related polypeptides are grouped together in chro- mosome or plasmid segments known as operons. The most important reg- ulatory mechanism is the positive or negative control of transcription initia- tion. This control function may be exercised by individual localized genes, the genes of an operon or genes in a regulon. The noncoding interposed sequences (introns) normally seen in eukaryotic genes are very rare.
