KLA210 Microbiology


API 20E identification strips were previously inoculated with 6 different isolates of bacteria


In the given morphology it is also for biochemical work. In this, the bacteria are identified routinely. In this, the identification is done by us. It is biased on the phenotypic analysis and after that era does the comparison of the known traits and the strain. Then again, in this, the consumer takes much of the time in this the labor is also intensive. In this, they need to solve the issue in a different company, but in the present, they need to work in the labor work and the intensive relation. It is the alternative.  No, it seems to be useful and saves time, and is less labor intensive. , it does the simplification of the result in the given process. There is one of the best examples of it is API 20E strips for the tests, it’s the way to do the determination of six unknown kinds of isolate and it is identified what the things are (Khalifa, et al., 2016).

API 20E known as a plastic strip that contains the 20 kinds of chambers for the test it is available in the small size it is also helpful to contain the two kinds of the isolation Work plan and the isolation area. It is helpful to do the deduction of the activity of the different enzymes. If it do the communication effectively it is relates with the fermentation of the carbohydrates of the catabolism of protein also for the amino acid include with the inoculated organism. It is work regarding to do the identification of the gram and positivity and the negative bacteria. It boos also the yeast formation and the capital observation biased on the different topics test and the capable driving with the accurate identification of the extensive part and the data baize. API full form is analytical profile index it is the method to do the identification regarding the biochemical. It is known as an objective and particular kind of the social experiment it is helpful to find the use of API 20E by paring needs of work planning and the procedure related to the step and getting the desired and the needed result.

T do the identification of it and do the ddifferentiate of it they had to gives the different kind of the methods and the evaluation process  (García-González, et al., 2018).


Material used

  1. API 20E it is the work regarding the identification of the strip and the previous work and the workforce to inoculated the 6 different kind of isolates of the bacteria.
  2. 16S rRNA sequence data (AlAli, et al., 2021).


  1. It is known as the confirmation regarding the culture and the test regarding the quick plan and the oxidase test for the cytochrome and C oxidized performed.
  2. We should pick one of the slides among the 6 different kind of the presented slides it is helps to make the suspension regarding the distilled water which is sterilized.
  3. After taken the API 20E they need to work for the strip and do the identification of the regent into the 20 separate compartments. This is represented in the given strip after we keep the use of the Pasteur pipette and it is filled up with the suspension of the bacteria.
  4. After we will into the oil for sterile and the purpose into the ADH, LDC, ODC, H2S, and URE blocks .
  5. We need to add a few water drops into the tray and add some API strips and they you should close the tray.
  6. After you put the mark in it, there is the number of the identification ad the motive are remembered which was the don’t give and the don’t mixed up things in in this we put the date and the initials for the more accuracy.
  7. After all of that procedure we need to try that the count of the identification of the needs and the purpose it could to be remember at the constant temperature of the 37 degree Celsius it is above and the between the 18 to 24 hours. After they need to give them the right work and the right desire of the given work part and the work policy with ready to observe (D’ALESSANDRO, et al., 2014).

Prior preparation

(In this the 6 of the strip were inoculated, which is given per the work and the given structure. It is manufacture by all of the six strips and the given suspension of the six kind of the different bacteria it were the incubated over the night at the temperature of the degree Celsius and he chamber of humidity.

It is work to dehydrate the substrates to present the strip work detected. As per the instructions of the manufacturers. It is work with all of the six strip in the order of suspension it is work by the enzymes ND workforce and thee experiment will fail.)


The result is based on the different kinds of changes in the exhibits after the experiment is done it is based on the color, odor, elevation, and margin, etc.

For example, the interception between the observation and the determination of the result.

For some of the given cells in the tray the color changes and give the sign if the indicator, it is a first sign off visible indicator after the given result. But before the making of sort and the any kind of interpretation some of these reagents has need to be put into it that will be used are TDA, and IND VP, this will require in very minor quantities (El Ayes, et al., 2015).

After the API  te reading scale baise on the colour chart it is impact on the both of the diferent levels like positive and the negative. It is work to lid a try and it is baised on the given result , and the seven given digit score it is work to allocation of the adding the value which is considered the individual counts aand the sevel kkind of the digit numbers (Salomon, et al.,  2014.).

The shape in given is could be changed.

  1. Form could be (punctiform, circular, filamentous, irregular, rhizoid, or spindle)
  2. Elevations are as (flat, raised, convex, pulvinate, urbanite)
  3. Margin is as (entire, undulate, lobate, erose, filamentous, curled).

It is baised on the result and n this the experiment shows the workpart above the mentioned work part and the criteria I is overcome which has the six kinds of experiment are as follow.

RESULTS BISED ON THE OBSERVATION the meaning of the above used and indicators are mentioned here.

Br is for brown, B is for black, G is for green, LB is for light brown. W is for white, Y is for yellow, o is for orange, PL is for pale yellow, BL is for blue, LP is for light pink, p is for pink.

A – klebsiella pneumoniae

B – pseudomonas flurescens

C – Escherichia coli

D – Enterobacter colacae

E – proteus mirabilis

F – Serratia marcesens


In this, on the behalf of they are shown the given result, it is became easy to do the identification of the substances and the given objects in the colour and the missing workpart and the reagents it is became the different part to conclude the colour, result, and the value they get the seven digits and the numerical word value, this result is provides the name of the given substance and hence the practical work against the done part. In this the result werw concluded with use of the API 20E and it is become the daily type of the tacking practical of the work and the work part.


Analysis of 16s rRNA sequencing data


Analysis of 16s rRNA sequencing data, 16s a basically work standard and the stand for the ribosomal ribonucleic acid , in the s for the Svedeberg it is basically for the unit and the small pat and the small subunit of prokaryotic and the ribosomes in rRNA also for the mito it is also for the mitochondria and also the chloroplast. It is generally work for the confused and the protein codeing gene is 16s RNA but it is not the ribsome is a must for the site of a binding site which is make the protein of the product able. It is helpful to reduce the proteins. It is the pert to do the comparison related to the tradition sequencing method. It is the work to use to the dining out and which is work for the 16 reran it is the much and the more effective in both of the terms where the financial condition help to reduce the manual work hghandeling work and the programmer. It is not for the fast but it has the effectively cost. Why it is the being the choice of the microbiologist it is also work for the commercial work plan and the commercial purpose it does have the lot of the issues but they need to work with the positive results in the comparison of the negative ones.  It is known as the central structure of the bacteria.

Findings –

It so known as the experiment about the work of the finding and give the result regarding the DNA result if the 16 reran it is the sequencing process to used and do the identification of the work and the effective bacteria. And sequence of a full genes has the possible and the recent. It has the sequence full of the germs and it has been possible recently. It is almost the 1500 biased pairs which is the approximate value but nit less than 1500 it is also work for the conversed reason. It is having the hyperveriable region from the v1 to the v9 and the again they leads to the taxonomic level of increment.

It is leading the complex situation of the DNA – DNA regarding the hyberaioidization of the because of it 16s rRNA work sequence use to do the identify bacteria at the special work plan and the special levels. It is help to assisting with the differentiate between the bacteria species which is relend very closely.

It is the thing it is observed maby of the clinically lebotpries and the plans. It is relay for the work methodit is the work and the part to do the identification of the analysis of bacteria and genomes in silicon there has been the total of the numbers of more than the 7k copies. Of worth 16s reran it is been identifying which is having the almost and the average of 4 copies per genome. It is more than that around of the 15% of genomes it is having the single print of 16s reran. It is almost 21% is having the two copies, 3 to 7 copies on every genome is being found. Founded.

In the nine variable regions they are being interpreted by the highest work and the conserved the 16s sequenced related to the 1500bp 16s reran gene. Sanger sequencing it is successful region relend to the successfully sequence of the entire work plan and the entire gene system. It is assembling approx… They are read the two or the three reads of every clone genes, generating and the assembling approx. two or three reds of every clone.

It is helps to spread the laboratory and the work process for the bop 16s Erna gene. Sanger it is the region successful and the successful sequencing of the covered and the entire gene, it is the work to generate and assembling the approx… It include the two and three leads of every clone.

16s reran Sequencing

In today time the 16s reran became the major tool of the choice and the term related to know the rational work between the work plan and the bacteria. It is the major tool of the choice I is widely work for the identification. All are bacteria they are preset]noted out they had the 16s rRNA Sequencing  (Sharifuzzaman et al.,  2018).

16s ribosomal databases are EzBioCloud, ribosomal database project, SILVA, and Green Genes.

Ezbiocloud database also known as ExTaxon has a total hierarchical taxonomic system and it has more than 60 k bacteria and archaea species and the quality of the bacteria and it is having known date of bacteria of about 15 k  which has the differen t plan and the difeeremt name and they are get published.

It is the data project reletd to the programmer, it is along with the related work and the work service it is also used as a crated the base and the calculated base of the data (Ferris, et al., 2017).

Bacterial identification using 16s rRNA sequencing

It is the kind of the___14 identification to do the species and the recognition of the biological profile. It is the work and the work plan to do the generation of the low identification of the commercial system. It is using the reran technique used for the sequencing of the genes. It is known as the large and the potential work technique. Because they had the large data base and the effectiveness of the cost.

It has been observed that for the case of genus identification the data which is being provided by using this technique is almost more than 90 % accurate and even more than that but not less on the other hand if we talk about species it has an accuracy level of nearly in between 65 to 83 %. (Séré, et al., 2015)


The reason which is the highly conserved that is the 16s reran in this the genes found the each and the every prokaryotic cells, and all of the bacteria covers it is not possible for the organism. To do the translate the mRNA without having the 16s reran and its part of the small bacteria.


After do the canalization of the different kind of the give scenarios that they place it is the effective an the clear that about the gene and the sequence information which is be presented in the given result of using the relend technique 16s it gives the accurate data only for the bacteria ND the public health. Or the clinical setting. But on the other hand it is also been observed that the data which is out after the using.
