Antilisterijski efekat dodatog Lactococcus lactis ssp. lactis tokom proizvodnje mekog belog sira
Get PDFThis study examined strains of lactic acid bacteria isolated from Zlatar cheese produced by the traditional method. Conventional microbiological testing resulted in the isolation of 96 strains of lactic acid bacteria which were then subjected to molecular genetic tests. One of the isolates, designated as Lactococcus lactis ssp. lactis, showed a markedly antilisterial effect under laboratory conditions. Based on the results, further research involved determination of its potential antilisterial effect during soft white cheese production. During fermentation that lasted 21 days, in experimental cheeses inoculated with Listeria monocytogenes ATCC 19111 combined with Lc. lactis spp. lactis culture, there was a reduction in Listeria cell count (by 3-4 log units), which can be considered important potential for biological control in soft white cheese production.U radu su ispitivani sojevi bakterija mlečne kiseline izdvojeni iz zlatarskog sira, koji je proizveden u skladu sa načelima tradicionalne proizvodnje. Primenom klasičnih mikrobioloških testova izolovano je 96 sojeva bakterija mlečne kiseline, koje su zatim podvrgnute molekularno genetskim ispitivanjima. Jedan od izolata, koji je označen kao Lactococcus lactis ssp. lactis ispoljio je u laboratorijskim uslovima izražen antilisterijski efekat. Na bazi tih rezultata vršena su dalja istraživanja radi utvrđivanja njegovog potencijalnog antilisterijskog efekta tokom proizvodnje mekog belog sira. Tokom procesa fermentacije sira, koji je trajao 21 dan, u oglednoj grupi sira u koju je inokulisana Listeria monocytogenes ATCC 19111 zajedno sa kulturom Lc. lactis spp. lactis došlo je do redukcija broja ćelija listerije u siru (za 3-4 log), što se može smatrati znаčајnim pоtеnciјаlom biоlоške zаštitе u njegovoj prоizvоdnji

Get PDFThe aim of these researhes was to examine the impact of year and foliar application
of molybdenum on germination capacity and absolute mass of alfalfa seed. In the
investigation year, meteorological factors showed large variations and great impact on
germination capacity and size of seed. Observed by years, absolute mass ranged from
1.82 g to 2.02 g. Germination ranged from 72.85% to 86.5%. Germination and 1000
seed weight were the worst in the year when high total precipitation and precipitation in
the period of flowering, pollination and seed filling were observed (June, July, August).
Foliar application of molybdenum showed no effect on size of alfalfa seed and
germination.Ispitivan je uticaj godine i folijarne primene molibdena na klijavost i
apsolutnu masu semena lucerke. U ispitivanim godinama meteorološki faktori su
pokazali veliko variranje i veliki uticaj na klijavost krupnoću semena. Posmatrano po
godinama, apsolutna masa se kretala u intervalu od 1,82 g do 2,02 g. Klijavost se
kretala u intervalu od 72.85% do 86.5%. Klijavost i masa 1.000 semena su najlošiji u
godini kada su zabeležene velike ukupne količine padavina i količine padavina u
periodu cvetanja, oprašivanja i nalivanja semena (jun, jul, avgust). Folijarna primena
molibdena nije pokazala značajan uticaj na krupnoću i klijavost semena lucerk

Antioksidativni potencijal anjona galne kiseline u reakciji sa različitim radikalima
No full textIn this paper antioxidative mechanisms HAT, SPLET and SET-PT of the
carboxylate anion of gallic acid (GA¯) with different radicals (OO−, OH, and CH3OO)
were investigated. For this reason were examined ΔHBDE, ΔHIP and ΔHPA values of the
corresponding reactions in water and pentyl ethanoate as solvents. For this purpose the
M052X/6-311++G(d,p) theoretical models was applied.
It was found that SET-PT is not favorable reaction path for all anions of GA (GA¯) in
both solvents. On the other hand, HAT and SPLET mechanisms are competitive in all
cases. Which of mentioned reaction path is predominant depends on the properties of
anions, radicals and solvents.U ovom radu su ispitani HAT, SPLET i SET-PT mehanizmi antioksidativnog
delovanja karboksilatnog anjona galne kiseline (GA¯) sa različitim radikalima (OO−,
OH i CH3OO). U tom cilju ispitane su ΔHBDE, ΔHIP i ΔHPA vrednosti odgovarajućih
reakcija u vodi i pentiletanoatu kao rastvaračima. Za to je korišćen M052X/6-
311++G(d,p) teorijski model.
Nađeno je da SET-PT mehanizam nije povoljan reakcioni put niti za jedan anjon
galne kiseline (GA¯) u oba rastvarača. S druge strane, HAT i SPLET mehanizmi su
konkurentni u svim slučajevima. Koji od reakcionih puteva je predominantan zavisi od
osobina anjona, radikala i rastvarača

Get PDFIn this study we investigated the potential probiotic properties of Lactobacillus
plantarum L 24 - 2, Lactococcus lactis biovar diacetylactis N 237 and strain
Micrococcus sp. It has been found that microbial species exhibited the ability to survive
under conditions of high concentrations of bile salts (2.0%) and low pH (2.0). This
ability varies for different types, but they will remain until the end of experiments
zivotosposobne. This, together with the antimicrobial activity projavljenoj them makes
them suitable for the new composition uklucivane the starter culture, which can be
effectively used as an antimicrobial barrier to the development of pathogenic bacteria in
the manufacture of a crude - product of dried meat.U ovom radu su ispitivana potencijalna probiotska svojstva bakterija
Lactobacillus Plantarum soj L 24 - 2, Lactococcus lactis biovar diacetilactis soj N 237 i
Micrococcus sp. Utvrđeno je da mikrobne vrste pokazuju sposobnost za preživljavanje
pod uslovima visoke koncentracije žučnih soli (2,0%) i niskog pH (2.0). Ova
sposobnost varira kod različitih ispitivanih bakterija, ali sve one ostaju životno sposobne
do kraja eksperimenata. Ovo, zajedno sa dokazanom antimikrobnom aktivnošću čini ih
pogodnim za uključivane u sastav novih starter kultura, koje mogu efikasno poslužiti
kao antimikrobna barijera za razvoj patogenih bakterija u proizvodnji sirovih - sušenih
proizvoda od mesa
Zdravstveno-reproriduktivni problemi svinja na komercijlanim farmama
Get PDFIt is well known that good health is a prerequisite of good pig reproduction or
successful and profitable production of pig. The health status of the herd depends on
many factors, such as the maintenance technology, nursing, nutrition, organization, level
of staff training and the systematic implementation of health care. Today we are
witnessing a large number of bacterial diseases, viral etiology and certain parasites can
seriously affect the production of pigs in intensive farming. These diseases are applying
prophylactic and therapeutic measures, as well as increased surveillance of professional
services to keep under control. The aim of the intensive farming of pigs on commercial
farms to produce a large number of weaned piglets and fattening pigs per sow per year.
To achieve this goal it is necessary to establish a high reproductive efficiency of
breeding animals. This can be achieved by adequate health care, modern technology and
good organization of production with the use of appropriate procedures in the
technology of artificial insemination. Biosecurity, welfare, good manufacturing
practices and risk analysis at critical control points are very important elements in
intensive pig production and using of biosecurity measures is critical to protecting the
health and success of the production.Dobro zdravlje svinja predstavlja preduslov dobre reprodukcije, odnosno
uspešne i profitabilne proizvodnje u svinjarstvu. Zdravstveni status stada zavisi od
velikog broja činilaca , kao što su su tehnologija držanja, nege, ishrane, organizacija,
stepen obučenosti kadrova kao i sistematsko sprovođenje mera zdravstvene zaštite.
Danas smo svedoci da veliki broj oboljenja bakterijske,virusne etiologije kao i pojedine
parazitoze mogu ozbiljno ugroziti proizvodnju svinja u intenzivnom uzgoju. Ove bolesti
moguće je primenom profilaktičkih i terapeutskih mera, kao i pojačanim nadzorom
stručnih službi držati pod kontrolom. Cilj intenzivne proizvodnje svinja na
komercijalnim farmama je proizvesti što veći broj odbijene prasadi odnosno tovljenika
po krmači godišnje. Za postizanje ovog cilja neophodno je uspostaviti visoku
reproduktivnu efikasnost priplodnih životinja. To se može postići adekvatnom
zdravstvenom zaštitom, savremenom tehnologijom i dobrom organizacijom proizvodnje
uz primenu odgovarajućih postupaka u tehnologiji veštačkog osemenjavanja
Akutni inflamatorni odgovor krava u ranoj laktaciji i mogućnost njegove kontrole nesteroidnim antiinflamatornim lekovima
Get PDFThere is growing metabolic stress and signs of acute inflammation in cows in early
lactation. The acute inflammatory response and metabolic status of cows are related to
each other, so that dominance of homeorhetic process leads to the development of acute
inflammatory response, which further emphasizes homeorhetic adaptation. These
processes can significantly collapse state of health and the value of a productivity in
cows. In this paper we described the possibility of interruption of the feedback using
non-steroidal anti-inflammatory drugs in cows in early lactation. We have described
effects of flunixin, ketoprofen and acetyl salicylic acid of the inflammatory response
and the health of the cows.Kod krava u ranoj laktaciji postoji izražen metabolički stres i znaci akutne
inflamacije. Akutni inflamatorni odgovor i metabolički status krava su u međusobnoj vezi,
tako da dominacija homeretskih procesa dovodi do razvoja aktutnog inflamatornog
odgovora, koji dalje potencira homeoretsku adaptaciju. Navedeni procesi mogu značajno
da uruše zdravstveno stanje i produktivne vrednosti krava. U ovom preglednom radu
opisana je mogućnost prekida ove povratne sprege upotrebom nesteroidnih
antiinflamatornih lekova kod krava u ranoj laktaciji. Opisani su efekti fluniksina,
acetilsalicilne kiseline i ketoprofena na inflamatorni odgovor i zdravlje krava
