Bacteriocins Lactobacillus – an alternative to antimicrobial drugs
(2021) Voloshina, Iryna; Soloshenko, Kateryna; Krasinko, Victoria; Lych (Tkachenko), Inna; Shkotova, Lyudmila
The review presents the characteristics of bacteria of the Lactobacillus family and their ability to synthesize various bacteriocins. The classification of lactobacilli bacteriocins is given, which includes three classes: class I – lantibiotics (peptides with a molecular weight of less than 5 kDa, which containing lanthionine), class II – unmodified bacteriocins, also called non-lantibiotics (heat-resistant peptides, which do not contain lanthionine and have a molecular weight of less 10 kDa) and class III – a poorly studied group of thermolabile proteins with a molecular weight of more than 30 kDa. Lactobacilli are shown to synthesize a wide spectrum of bacteriocins, which demonstrate a variety of actions and are able to inhibit the growth of numerous species of opportunistic gram-positive microflora. The article also provides the examples of lactobacilli bacteriocins isolated from food products (fermented meat, fish, kombucha, goat milk, koumiss, etc.) and various human biotopes (microbiota of breast milk, intestinal tract, and vaginal secretions). Additionally, the review shows the prospects of wide application of bacteriocins synthesized by lactobacilli in the food and pharmaceutical industries.
Environmental belief of students in higher technical educational institutions – the path to harmonious relationship between technogenic society and nature
(2011) Skrotska, Oksana; Voloshina, Iryna; Krasinko, Victoria; Lych (Tkachenko), Inna; Teterina, Svitlana
The article is devoted to the consideration of ways of the topical problems decision which get in way of harmonization of relations between technogenic society and the nature. It also devoted to the analysis of state of training of specialists on ecological orientation in the higher technical educational institutions.
Iron-mediated removal of ammonia from strong nitrogenous wastewater of food processing
(2004) Ivanov, Volodymyr M.; Wang, J.-Y.; Stabnikova, Elena; Krasinko, Victoria; Stabnikov, Victor; Tay, Stephen; Tay, Joo
The combination of microbial reduction and further microbial oxidation of iron was applied to the treatment of food-processing wastewater and recovery of ammonium. Fe2+ ions were formed by iron-reducing bacteria under anaerobic conditions. Ammonium was recovered by co-precipitation with negatively charged iron hydroxides produced during oxidation of Fe2+ by iron-oxidizing bacteria under microaerophilic conditions. The value-added by-product of this process can be used as a slowly released ammonium fertilizer.
