Bacteria future trends

This chapter is divided into five sections including an introdnction (Section 17.1), impact of yeast on beer appearance (Section 17.2), impact of yeast on beer flavour (Section 17.3), impact of bacteria on beer appearance and flavour (Section 17.4), and future trends (Section 17.5). The emphasis is on the impact of yeast on beer appearance and flavour because more information is available on this topic. Although most of the discussions are centred on the impact of main brewing yeast strains (Saccharomyces cerevisiae and Saccharomycespastorianus) on barley malt-based beers (ale and lager, respectively) (Lodolo, Kock, Axcell, Brooks, 2008 Stewart, Hill, Russell, 2013), references are also made to other yeasts involved in brewing specialty beers derived from both barley malt and other cereal malts. Lactic acid bacteria (LAB) are the focus of discussion with regard to bacterial impact on beer appearance and flavour due to their relatively common occurrences in beers (Menz et al., 2010 Sakamoto Konings, 2003 Suzuki, 2011 Suzuki, Asano, lijima, Kitamoto, 2008).

However, disinfectant household cleaners are also more likely now to be mentioned in newspaper and magazine articles as contributing to the problems of antibiotic-resistant bacteria these tend to be reports in the popular press where all antimicrobial products tend to be mentioned, despite no demonstrated scientific link between the household cleaner disinfectants and the problem [172-174], As noted, disinfectant cleaners continue to have popularity, but given some of the trends in microbial control issues, they may be either more heavily regulated or limited in the future.
