ANTIMICROBIAL ACTIVITY OF PORCINE OVARIAN FOLLICULAR FLUID ON Bacillus cereus AND COLIFORM BACTERIA in vitro
Potential antimicrobial activity of follicular fluid and its selectivity remains open questions in field of human and animal reproduction. In our work we examine antimicrobial activity of porcine follicular fluid on coliform bacteria, as Gram-negative, and B. cereus, as Gram-positive, by incubation of different dilatations of bacteria with follicular fluid in cultivation medium and microbiologi...
متن کاملAntimicrobial Effects of Honey on Bacillus Cereus
Abstract Background and Objective: Honey is a healthy and nutritious food that has been used for a long time as a treatment for different diseases. One of the applied properties of honey is its antimicrobial effect, which differs between different types of honey due to variation of phenolic and antioxidant compositions. This study aimed to assess antimicrobial effect of honey on Bacillus cereu...
متن کاملTransduction in Bacillus cereus and Bacillus anthracis.
A phage, designated CP-51, that carries out generalized transduction in Bacillus cereus and B. anthracis, has recently been isolated from soil. Transducing phages for members of the genus Bacillus have been described previously for B. subtilis and B. licheniformis (2-6). Those that have been best characterized are PBS-1 for B. subtilis (4) and SP-10 and SP-15 for both B. subtilis and B. licheni...
متن کاملEffect of inhibitors of trypsin-like proteolytic enzymes Bacillus cereus T spore germination.
The germination of Bacillus cereus T spore suspensions is partially prevented by several inhibitors of trypsin-like enzymes. Leupeptin, antipain, and tosyl-lysine-chloromethyl ketone are effective inhibitors, whereas chymostatin, elastatinal, and pepstatin are inactive. A synthetic substrate of trypsin, tosyl-arginine-methyl ester, also inhibits germination. Its inhibitory effect decreases as a...
متن کاملCharacterization of an a-Amylase with Broad Temperature Activity from an Acid-Neutralizing Bacillus cereus Strain
Bacillus sp. GUF8, isolated from acidic soil samples of a tea farm was identified as Bacillus cereus, based on 16S rDNA sequencing and standard bacterial identification methods. Following optimization of enzyme production, the resulting α-amylase was purified by acetone precipitation and ion exchange chromatography. Consequently, thermostability and kinetic parameters of the purified enzyme wer...
