I am doing an experiment of Bacillus subtilis on death kinetics. As it is a spore forming bacteria, will the spore affect the death kinetics results?
Growth kinetics is the explanation of the growth rate of a microbes and also its substrate concentration. The growth kinetics of the death of Bacillus spores are suspended in phosphate buffer that can has a temperature range from 127.2 to 143.8 C and can also exposure that achieved with the help of a tubular flow reactor that contain suspension of a spores that are injected into a hot flowing stream at the starting entrance of the reactor. After the flow from a fixed length of the reactor the suspension of the hot stream was considered ,as the stream contains the spores then it can be cooled by vaporization. Here the death rate will be fitted by logarithmic expression than can approximated by exposure and the death rate can be obtained from the portion were growth was found to correlate by Arrhenius.
In most of the cases the processed food is based on ultra high temperature which can undergo the sterilization with a subsequent delivery that has a rapid sealing and as the spore forming bacilli that present on equipment surface, the material cause spoilage of the decontamination of the packing material is very much essential in order to prevent spoilage. The death time curves can be founded and the activation of energy that can be frequently constant in relationship fit of the data. The standard changes for Absolute Reaction Rate Theory relationship data can be found respectively.

I am working on an experiment on the death kinetics of Bacillus spp. Is it advisable for me to incubate the micro seed in peptone water, as well as the food sample I am testing, as a comparison? Or I do not even need to do a comparison, and just focus on my food sample. Thank You.
I am doing an experiment on the kinetics bromide bromate reaction. is it possible that my order of reaction does not correspond to the mole ratio of the reactant in the stoichiometric equation?
I am doing an experiment on fluidization. The fluid used for the experiment is gas (air). I need to know the viscosity to do some calculations. However, when I search the internet, it seems that I have found different values. May I know what is the common value use for the air at room temperature viscosity?
1. The graph below depicts the growth of a
Gram-positive, spore-forming bacterium Bacillus thuringiensis (B.
t.). This species normally lives in the soil as well as the
alkaline gut of insects.
a) Label on the graph the phases of this growth cycle.
Below, describe the important features of each phase.
b) The graph shown was obtained by culturing B. t. in
media containing only minimal amounts of nutrients and salts. Draw
a growth curve on the same graph that would...
I am doing an experiment to find out the content of phosphate composition in cola beverage by UV-visible spectrophotometry and pH titrimetry And I find the different: 7.05 x 10-3 (from UV-visible spectrophotometry) - 6.32 x 10-3 (pH titrimetry) =7.3 x 10-4 M Why there is such a difference for concentration using UV-visible spectrophotometry was greater than pH titrimetry? Thank You.
I am doing a free-falling experiment with five trials with a meter stick and need to calculate reaction time (s). I need to convert to both SI units and English units. My stats are Fall Distance 1: 31cm Fall Distance 2: 20cm Fall Distance 3: 22cm Fall Distance 4: 15cm Fall Distance 5: 14cm 1. I need to calculate the reaction time for each and then the average reaction time 2. I need to show conversion of fall distance from English...
I am doing the experiment, "Determination of Specific

I am doing a paper on a change theory and I'm using Lewin's 3 step. I am trying to change the way we care for the transgender population. asses the factors that are likely to affect the implementation of recommend activities, and also identify evidence based rationals to propose how to address them. using lewins change theory. what stakeholders would be involved?
Hello, I am not sure what I am doing wrong.
Could someone please explain :)
Thank you!
The mineral dolomite contains magnesium carbonate. This reacts with hydrochloric acid. MgCO3(s) + 2 HCl(aq) + CO2(g) + MgCl, (aq) + H20(0) a. Write the net ionic equation for this reaction and identify the spectator ions. (If needed, use H3O+ for the hydronium ion. Use the lowest possible coefficients. Use the pull-down boxes to specify states such as (ag) or (3). If a...
We are doing a full wave bridge rectifier experiment and I am
asked to make a lab report. In the conclusion section we are asked
to answer questions that I don't really understand. The questions
are posted below.
I need help with the second through fourth bullet points.
Thanks!
