  • pH Tech Tips (.pdf)

    The Concentration ratio of hydrogen ions (H+) and hydroxyl ions (OH-) determine the pH value of a solution. Any hydrogen activity will produce a 59.16 mV/ pH unit across the glass membrane. The measurement is expressed on a scale of 0.0 to 14.0. Water with a pH of 7 is considered neutral (H+ ions

    Here you go. Miller 3 ph converter design. All you need to know about making a good reliable and stable phase converter of your own. I am the same guy there as here so I know the design works well!

  • Re: Converting 3 Phase to 1 Phase in Reverse?

    Thanks for the PM you sent me. I will try and work up some better details as I have time. Fist thingiI would suggest is looking fore schematics for 9 lead and 12 lead dual voltage three phase motors then read up on what a zig zag or 'Z" connection is regarding getting single phase form three phase.

  • Sensitive acid sensor controls insulin production

    Many human metabolic functions only run smoothly if the acid level in the body remains neutral and stable. For humans, normal blood pH values lie between 7.35 and 7.45. By way of comparison, an empty stomach is extremely acidic, with a pH value of 1.5. A team of bioengineers have now developed a new implantable molecular device composed of two modules: a sensor that constantly measures blood pH and a gene feedback mechanism that produces the necessary amount of insulin.

  • Bacteriophages as antimicrobial agents against bacterial contaminants in yeast fermentation processes

    Background: The emergence of biofuels produced through yeast fermentation represents an important avenue for sustainable energy production. Despite all its advantages, this process is vulnerable to contamination by other organisms - most commonly lactic acid bacteria - that are present in raw feedstocks and/or in production lines. These contaminants compete with the yeast for nutrients, reducing the overall biofuel yield, and release substances that inhibit yeast growth. Here, we investigated the application of bacteriophages as potential antibacterial agents in yeast fermentation. Results: Experiments conducted to understand the impact of pH on yeast, bacterial, and phage development showed that the yeast Saccharomyces cerevisiae Superstart? grew in a similar fashion at pH levels ranging from 3 to 6. Growth of Lactobacillus plantarum ATCC? 8014? was inhibited by pH levels of less than 4, and phages ATCC? 8014-B1? (phage B1) and ATCC? 8014-B2? (phage B2) displayed different infectivities within the pH range tested (pH?3.5 to 7). Phage B1 showed the best infectivity at pH?6, while phage B2 was most virulent at pH levels ranging from 4 to 5, and the cocktail of these phages showed highest infectivity in the range from pH?4 to 6. Population dynamics studies in MRS medium at pH?6 showed that, in the presence of bacteria inoculated at 107 cells/ml, yeast cultures were impeded under aerobic and anaerobic conditions, showing major decreases in both cell yield and ethanol production. The addition of the phage cocktail at a low initial multiplicity of infection was sufficient to reduce contamination by over 99%, and to allow yeast and ethanol yields to reach values equivalent to those of axenic cultures. Conclusions: From the results observed, phages are good candidates as antimicrobial agents, to be used in place of or in conjunction with antibiotics, in yeast fermentation processes. Their implementation with other common contamination abatement/prevention methods could further increase their efficacy.
