Example sentences: retain

Nevertheless, 50% of the initial activity was retained when nisin was treated with papain.

Example sentences: retain

Nevertheless, 50% of the initial activity was retained when nisin was treated with papain.

Example sentences: ability

The ability of Lactococcus lactis subsp. lactis CECT 539 and Pediococcus acidilactici NRRL B-5627 to produce bacteriocins on both diluted and concentrated whey was investigated in batch fermentations.

Example sentences: information

To date, only limited information is available concerning the occurrence of bacteriocins among ruminal isolates or the sensitivity of ruminal microorganisms to exogenous bacteriocins.

Example sentences: temperature

Permeabilization of the outer membrane of E. coli strains with EDTA and Na lactate combined with lactocin 705/AL705 showed to be valuable in controlling this foodborne bacteria at low temperatures.

Example sentences: find

Nisin-producing lactic acid bacteria were the most abundant, but lacticin 481-producing lactococci and AS-48-producing enterococci were found at relatively high rates.

Example sentences: investigate

Antimicrobial activity of reuterin in combination with different bacteriocins from lactic acid bacteria against food-borne pathogens in milk was investigated.

Example sentences: wide

Bacteriocins of lactic acid bacteria have been widely studied in recent years.

Example sentences: focus

This review focuses on the purification procedures used with bacteriocins of lactic acid bacteria and conveys some of the problems associated with this process as well as some of the lessons learned.

Example sentences: range

The range of inhibitory activity by bacteriocins of lactic acid bacteria can be either narrow, inhibiting only those strains that are closely related to the producer organism, or wide, inhibiting a diverse group of Gram-positive microorganisms.

Example sentences: feasible

Refrigerated milk treated with both natural antimicrobials would mean a feasible system to control pathogenic contaminants.

Example sentences: classification

This review discusses the classification, structure, production, regulation, biological activity, and potential applications of such two-peptide bacteriocins.

Example sentences: immunity

As a result of these studies, insight has been gained into various fundamental aspects of biology and biochemistry such as bacteriocin processing and secretion, mechanisms of cell immunity, and structure-function relationships.

Example sentences: toxic

The production of toxic compounds or antibiotics is a common component of intermicrobial competitive interactions, and many of these toxins have been adopted and adapted for the control of microbial populations.

Example sentences: treatment

Treatment with EDTA (500 and 1000 mm) and Na lactate (800 mm) alone produced a variable effect depending on the strain, Na lactate being inhibitory against E. coli NCTC12900 at both assayed temperatures while EDTA (1000 mm) led to its inactivation only at 6 °C.
