During the global 2020 COVID-19 outbreak, advantages of online food delivery (FD) were obvious, as it facilitated consumer access to prepared meals and enabled providers keep operating. However, FD is not without its critics, with reports restaurant boycotts. It is, therefore, time take stock consider broader impacts FD, what they mean for stakeholders involved. Using three pillars sustainability a lens through which impacts, this review presents most up-to-date research in field, revealing...
Biofilms on the surfaces of dairy manufacturing plant threaten quality and safety products. processing lines are characterised by rapid development (< 12 h) predominance single species bacteria (e.g. Streptococcus thermophilus or Bacillus spp.). Increased times, more complex systems demands for higher products have contributed to increased recognition problems posed biofilms. The growth biofilms surface plate heat exchanger pasteurizers can contaminate milk with > 106 ml‐1 this affects...
Fermentation by lactic acid bacteria (LAB) is a promising approach to meet the increasing demand for meat or dairy plant-based analogues with realistic flavours. However, detailed understanding of impact substrate, fermentation conditions, and bacterial strains on volatile organic compounds (VOCs) produced during lacking. As first step, current study used defined medium (DM) supplemented amino acids L-leucine (Leu), L-isoleucine (Ile), L-phenylalanine (Phe), L-threonine (Thr), L-methionine...

The luxS gene of Lactobacillus reuteri 100-23C was amplified by PCR, cloned, and then sequenced. To define a physiological ecological role for the in L. 100-23C, mutant constructed insertional mutagenesis. did not produce autoinducers AI-2 or AI-3. Complementation mutation plasmid construct containing restored AI-3 synthesis. In vitro experiments revealed that neither growth rate, nor cell yield, survival stationary phase were compromised relative to wild type complemented mutant. ATP...
ABSTRACT Processes by which fecal bacteria enter overland flow and their transportation state to surface waters are poorly understood, making the effectiveness of measures designed intercept this pathway, such as vegetated buffer strips, difficult predict. Freshly made aged (up 30 days) cowpats were exposed simulated rainfall, samples cowpat material runoff collected. Escherichia coli in separated into attached (to particles) unattached fractions, fraction was analyzed determine if cells...
ABSTRACT A laboratory-scale model system was developed to investigate the transport mechanisms involved in horizontal movement of bacteria overland flow across saturated soils. suspension Escherichia coli and bromide tracer added system, concentration number attached unattached E. cells were measured over time. Analysis breakthrough curves indicated that transported together, presumably by same mechanism. This implied advection with flowing water. Overland-flow could be significantly reduced...
Chemical changes that occur within a microbial biofilm during development on germanium internal reflection element (IRE) were monitored by attenuated total Fourier transform infrared spec‐troscopy (ATR/FT‐IR) for 188 h. The amount of protein detected at the IRE/medium interface increased throughout course experiment. Extracellular polysaccharides mainly produced initial stages development. These results demonstrate in metabolic activity surface‐associated bacteria surfaces exposed to flowing...
ABSTRACT Spores from four Geobacillus spp. were isolated a milk powder manufacturing line in New Zealand. Liquid sporulation media produced spore yields of ∼10 7 spores ml −1 ; purified using two-phase system created with polyethylene glycol 4000 and 3 M phosphate buffer. The zeta potentials the isolates ranged −10 to −20 mV at neutral pH, an isoelectric point between pH 4. Through contact angle measurements, found be hydrophilic had relative hydrophobicity values 10 40%, as measured by...
