During wine production and storage, undesired effects can appear mainly due to the microbiological activity of present microorganisms leading economic losses. Wine stabilisation is needed for controlling unwanted improve safety final quality. Nowadays, a plethora viticultural technological solutions available but, in some cases, process changes sensory profile. The aim this study was developmen...

objective(s):   the ongoing increasing antibiotic resistance is one of the biggest challenges faced by global public health. the perennial need for new antimicrobials against a background of increasing antibiotic resistance in pathogenic and opportunistic microorganisms obliges the scientific community to constantly develop new drugs and antimicrobial agents. lichens are known prolific sources ...

Nowadays, consumers are demanding natural and safe foods with no additives, reduced quantities of salt and no need to be cooked [9]. However, the emergence of psychrotrophic foodborne pathogens is an important cause of concern. To guarantee the safety of minimally processed foods, there is an intense research on natural antimicrobials derived from animals, plants and microorganisms. Bacteriocin...

The emergence of new infectious diseases, the resurgence of several infections that appeared to have been controlled and the increase in bacterial resistance have created the necessity for studies directed towards the development of new antimicrobials. Considering the failure to acquire new molecules with antimicrobial properties from microorganisms, the optimization for screening methods used ...

The purpose of this study was to set a benchmark for a monitoring and surveillance programme on the volumes of antimicrobials available and consumed by animals for the benefit of animal health in South Africa. This survey was collated from data available from 2002 to 2004. The authorised antimicrobials available in South Africa were firstly reviewed. The majority of available antimicrobials...

Penicillin and other antimicrobials discovery revolutionized medicine but, as a consequence of antibiotic misuse, several bacteria evolved to become resistant to multiple antibiotics classes: “the superbugs”. Following the stagnation on the conventional antibiotic-discovery field, scientific attention turned to alternative foundations for the development of novel antibacterial substances, namel...

In recent years, increasing in the level of public health consciousness has led to a drastic decrease in the use of synthetic food preservatives. Therefore, there has been a growing demand for novel antimicrobials. Apart from that, finding low cost sources has been always an important issue for food marketers. The present study was designed to investigate in-vitro antibacterial activities of gr...

Biofilm-associated bacteria are less sensitive to antibiotics than free-living (planktonic) cells. Furthermore, with variations in the concentration of antibiotics throughout a biofilm, microbial cells are often exposed to levels below inhibitory concentrations and may develop resistance. This, as well as the irresponsible use of antibiotics, leads to the selection of pathogens that are difficu...
