Abstract

Bacteriocins are antimicrobial peptide compounds derived from gram-positive and gram-negative bacteria. Bacteriocins can be cationic, anionic, and neutral. These compounds are synthesized in bacterial ribosomes and have a broad spectrum of activity against pathogenic bacteria. Some bacteriocins from lactic acid bacteria used in the food industry are nisin, diplococcin, acidochilin, bulgarican, helventicin, lactacin, and plantaricin. Bacteriocins produced by Pediococcus spp., which are known as pediocins, can be used as alternative preservatives in the food industry. Another type of bacteriocin is plantaricin, which is produced by a group of gram-positive bacteria, Lactobacillus plantarum, and can inhibit growth and kill a group of gram-negative bacteria that are pathogenic. Bacteriocins derived from lactic acid bacteria and used as biopreservatives have several advantages, namely a) they are not toxic and biodegrade easily because they are protein compounds; b) they do not harm the intestinal microflora because they are easily digested by enzymes in the digestive tract; c) they can reduce the use of chemical food preservatives; and d) they are highly versatile and can be utilized in various forms such as the form of bacteriocin-producing bacterial culture strains or purified or semi-purified bacteriocin compounds.
Bacteriocın, Plantaricin和Pediocin Bıosynthesis在乳酸菌中的应用,抗菌机制和作为食品防腐剂的应用综述
细菌素是从革兰氏阳性菌和革兰氏阴性菌中提取的抗菌肽化合物。细菌素可以是阳离子、阴离子和中性的。这些化合物是在细菌核糖体中合成的,对病原菌具有广谱活性。食品工业中使用的乳酸菌中的一些细菌素是乳链菌素、双球菌素、嗜酸菌素、保加利亚菌素、海尔文霉素、乳腺泡素和植物菌素。由Pediococcus spp.生产的细菌素,被称为足霉素,可在食品工业中用作替代防腐剂。另一种细菌素是植物素,它由一组革兰氏阳性菌植物乳杆菌产生,可以抑制生长并杀死一组致病的革兰氏阴性菌。来源于乳酸菌并用作生物防腐剂的细菌素具有几个优点,即a)它们无毒且易于生物降解,因为它们是蛋白质化合物;b) 它们不会伤害肠道菌群,因为它们很容易被消化道中的酶消化;c) 它们可以减少化学食品防腐剂的使用;和d)它们是高度通用的,并且可以以各种形式使用,例如产生细菌素的细菌培养菌株或纯化或半纯化的细菌素化合物的形式。
