The relationship between water activity (aw), lactate, and growth of Listeria monocytogenes strain Scott A was studied in a meat model system consisting of cooked strained beef ranging in moisture content from 25 to 85% (wt/wt). Lactate (4%) depressed meat aw, and differences between aw values in control and lactate-treated samples at each moisture level increased progressively with decrease in moisture, from 0.003 (85% moisture) to 0.046 (25% moisture). Maximum cell numbers per g in control samples stored at 20°C for 7 d were about 109 (45–85% moisture, aw= 0.981–0.994) and 107 (35% moisture, aw = 0.965); there was no growth in meat with 25% moisture (aw = 0.932). Sodium lactate (4%) suppressed listerial growth at >55% and inhibited growth in samples with 25–55% moisture (a < 0.964). Lactate concentrations less than 4% were not listeristatic, but combinations of 2 or 3% lactate with 2% NaCl in samples with 55% moisture inhibited growth. Potassium and calcium lactate were as effective as the sodium salt in suppressing growth and aw.

Abstract In prokaryotes, a major contributor to genomic evolution is the exchange of genes via horizontal gene transfer (HGT). Areas with a high density of HGT networks are defined as genetic exchange communities (GECs). Although some phenotypes associated with specific ecological niches are linked to GECs, little is known about the phenotypic influences on HGT in bacterial groups within a taxonomic family. Thanks to the published genome sequences and phenotype data of Lactic Acid Bacteria (LAB), it is now possible to obtain more detailed information about the phenotypes that affect GECs. Here, we have investigated the relationship between HGT and internal and external environmental factors for 178 strains from 24 genera in the Lactobacillaceae family. We found a significant correlation between strains with high utilization of sugars and HGT bias. The result suggests that the phenotype of the utilization of a variety of sugars is key to the construction of GECs in this family. This feature is consistent with the fact that the Lactobacillaceae family contributes to the production of a wide variety of fermented foods by sharing niches such as those in vegetables, dairy products, and brewing-related environments. This result provides the first evidence that phenotypes associated with ecological niches contribute to form GECs in the LAB family.

Self-powered wearable sweat-lactate analyzer has been developed for training analysis of rowing. Tetrapodshaped ZnO nanowires are attached onto ordinary textiles to form a device. Based on the coupling of enzymatic reaction (lactate oxidase and lactic acid) and piezoelectric effect, the device can be attached to the tester to monitor the driving frequency, rowing distance and sweat lactic acid concentration of the tester in real-time. The relationship between the rowing frequency and physiological state is obtained by monitoring the rowing process of the tester, which is helpful to formulate a training plan belonging to the rowing tester. This study provides a new direction for the scientific monitoring of kinematics and accelerates the development of wearable sports equipment.

The Relationship

AbstractWe consider the form of the probability density function for the ultimate muscle pH in slaughtered animals. Muscle pH in slaughtered animals is dependent on a biochemical process which forms lactic acid from the breakdown of glycogen stored in the muscle at slaughter. The relationship between glycogen and muscle pH after slaughter is expressed as a pair of coupled differential equations. The solution of this system for the equilibrium muscle pH as time → ∞ gives the form of the probability density for the ultimate muscle pH. When the initial density for the muscle glycogen is normal, the density for the ultimate muscle pH is shown to be approximately a mixed normal density.

The Relationship

SummaryIn suitable media the relationship between the citrate content and the acetoin formed by the growth ofStreptococcus lactisvar.diacetilactisNCDO 1007 is linear. An assay method for citrate is described which is based on this relationship. It has been used to assay the residual citrate in cultures of lactic acid bacteria and, therefore, to assess the ability of these bacteria to dissimilate citrate. Some suitable media for the test are described.

The Relationship

Infant Mortality Rate is one indicator that determines health status. Every year there are 3 million infant deaths in the world, 80% of which occur in the first 6 days of life, with pneumonia and diarrhea still being the main causes of death. Based on Nurita's research (2019) on postpartum mothers and newborns, which aims to determine the relationship between the frequency of giving colostrum and birth mode with the number of Lactic Acid Bacteria (LAB) colonies in the neonatal gastrointestinal tract. The results of the study found that the number of LAB colonies in babies born vaginally and C-Section was not much different, but the number of LAB colonies would increase in number if breast milk was often given. The education carried out targets an increase in the knowledge of educational participants with the outputs in the form of informative leaflets, educational video, educational X-Banners, activity reports and journal publications. Community service activities begin with licensing arrangements, time contracts, preparation of educational tools and materials, visits to Independent Midwives Practice (PMB, explanations of educational materials, discussions and questions-answers, showing educational videos, and handing over Educational X-Banners. It can be concluded that educational participants are still unfamiliar with lactic acid bacteria (LAB) and their role in the health of the baby's gastrointestinal tract, so further education is needed
