COMPLEMENTARY REACTIVES
We compile in this document all reactives and supplements which don´t need monographic brochure. Among them there are antibiotics and other selective agents to add to base mediums, chromogénicsubstrate,and other reactives. Most of them need the follow 8 special comments: 1- The different strains of microrganism vary their answers to differents selective supplements, matter which you must bear in mind to choose differents concentration if you don´t wish obtain falsenegatives from mix cultures.
2- Differents base medium can act different with a same supplement, same that differents supplements can act different with a same base medium. Culture mediums, with or without supplements, arechaotic mixing which you need a lot of experience to achieve a result. For that reason, it is not advisable mixsupplements in mediums don´t advisable for the producer, same as it is not advisable mix mediums from oneproducer with supplements from another producer.
3- A lot of supplements are photosensitive and thermolabile. Although they are keeped at darkness and at the fridge, when you reconstitute prepared medium can reappear the problem, Muchossuplementos son fotosensibles y termolábiles. Aunque se conserven en la oscuridad y en nevera, alreconstituir el medio preparado puede reaparecer el problema, for that reason you have to control their finalactivity.
4- Some components are toxics for the skin, mucous( eyes, lips, throat…) so you must handle with gloves, mask, glasses and a lot of caution. The most important are Sodium azide , Basic fucsine andSodium selenite, that in MICROKIT are included with base medium (KAA, KF, EVA Litsky, Rothe, ENDO,Selenito Cystina) to avoid its handle.
5- It is important make sure a goob mix of base medium with the supplements, because it can appears at a very low concentrations and its heterogeneous spread would be a big mistake.
6- You must used only material ( spatula, container, balance,…) clean, because of any impurity can affect the final results.
7- All sterile supplement must be handle with caution to avoid contamination.
8- All supplement no sterile must sterilize to prepare culture mediums, with two possibilities: A) If it is not thermolabile, adding to the base medium with water before autoclave.
B) If it is thermolabile, adding bidestiled water, shaking till complet disolution and sterilizing everything by filtartion ( better with syringe and sterile filter of frame, which finish in a needle directlly at thefinal sterile container. So, the probability of mistake is very lower than sterilization of higher volume withfunnel).
Bidestiled water sterile/no sterile.Keep: 4-25ºC.
Deal with bidestiled water of high quality that MICROKIT use in all prepared mediums and we recommend to all of our customers of dehidrated mediums ( our supplier, an important pharmaceuticalcompany, supply this product even as injectable- sterile-, but we DON´T supply this although at the originallabel say it). It is amazing the bad quality that other waters ( destiled for cars, destiled at some laboratoriesfrom running water…) contribute to other culture mediums, with rainfalls, displacement important at the pH,turnnings of colorings… And don´t speak about unacceptable faucet water, even in zonez with high qualityof thids water as all limestone and coastal zone of Spain.

They are TTC-reductors without inhibition (to concentration of 1-2 ml/l) most of bacterium (Streptococcus, Staphylococcus, Listeria, Aeromonas, Citrobacter, E.coli, Salmonella, Shigella, Serratia,Yersinia, Bordetella, Campylobacter.) and yeast (Saccharomyces, Cryptococcus, ciertas Candida.), withimportants exceptions among positive Gram (some Bacillus, Micrococcus, Lactobacillus), negative Gram(Legionella) and yeast (some Yarrowia, Pichia and Candida).
Tween 80 (Polisorbate 80 USP), liquid no sterile 100 ml (for 20-100 liters of medium LPT)
This agent decrease the superficial tension of the liquids. This have two important : 1- Allow to entrance more quickly of nutrients in microbian cells that are in contact with some mediums included, and one of the most important effects is that you obtain results more quicklythan growing.
2- Facilitate fat emulsion, mediums with lipydic reactives can homogenize better.
It is added to base mediums (LPT Neutralizing Agar Purple, LPT Neutralizing Broth Purple, Raka RayMedium.), before autoclave (although to dissolve you have to heat the water previously to 40 -80 ºC andshake), 1-5 ml per liter of medium to 35 ºC,before to sterilize. Keep: 15-25ºC.
Urea, Sterile liquid solution to the 40% in princkable bottles of 100 ml (for 2liters of medium)
UNE-EN 12824, UNE 34-818-85, UNE 34-554-83. Hydrolysis of Urea is catalysed by specific enzyme Ureasa, and give carbonate amonicum that alkaline the medium. Proteus is quickly positive, Yersiniaenterocolitica and Klebsiella are slow positive , yaest as Cryptococcus are also positive and Salmonella,Shigella and other enterobacteriumsare negatives. Add 50 ml per final liter of medium (Urea Agar, UreaBroth) aseptically and after sterilize the base medium and cold to 55 ºC. Keep: 4-8ºC.
Vaselin sterile liquid in princkable bottles 100 ml
It is used basiclly to blocked tubes, as paraffin or agar-agar, so create an anaerobic conditions in the medium are bellow. Keep: 4-25ºC.
VOGES PROSKAUER 1 (KOH)+ VP 2 (-naftol) kit 2 drop to drop to 5 ml each one
UNE 34-554-83. For exclusive USE in laboratory. Add the reactive 1 after than 2. Conatin - naftol (6 g/ 100 ml) and KOH (40 g/100 ml). Contain 5 + 5 ml. Keep: 4-8ºC.
Xylose, powder no sterile 500 g
Add 5 g of Xylosa sterilized by filtration to each liter of X/R Listeria Broth already autoclaved and cold.

¡NEW IRRADIATED SUPPLEMENTS ! SODIUM METABISULFITE (0'75 g)+

MIX OF INACTIVATORS SUPPLEMENTS (no sterile)
Designed by Laboratorios MICROKIT to add to classical Letheen Broth and inactivate the mostmodern preservative (also Amonium Cuaternario and phenol that are already inactivated byLecitina andl Polisorbato-Tween-80). Also is very usefull to add to modern LPT Neutralizing Brothwhen they have a lot of inactivators and then never appear ay generals countings, so we think thatour product is sterile and give false negatives.
Exclusive use in laboratory. Add 5.4 g of supplement per liter of Letheen or LPT Neutralizingmediums. Dissolve well. Sterilize.
This mix of supplements inactivate benzenic compounds (included parabenes and phenols), formol,iodine, chlorine and others halogens, bleach, derived mercurials, glutaraldehido.
CODE: SMT002 PRESENTATION: bottles of 100 g
KEEP: 15-21ºCwith bottle closed. VERY HIGROSCOPIC: Keep in environments with lowhumidity.
Sodium Tioglicollate: Sodium Disulphite: Sodium Tiosulphate: See also LPT Neutralizing Broth, our Letheen with new inactivator mix included.
Final user is the only responsible of destruction of grown microrganism according the currentenvironmental legislation. Autoclave before throw to the rubbish.
