Opis:
In this review we summarize stress factors that affect the lactic acid bacteria (LAB) and cause different molecular stress responses. LAB belong to a group of bacteria that is very widespread in food and beverages. They are present, and desired, in fermented products like yogurts, cheese, vegetables, meat or wine. In most of them, LAB are providing positive sensory and nutritive features. However, as harmless and desired microbes in one product, LAB can cause spoilage and a bad taste of others, especially in juices and beverages. LAB are resistant to many stress factors which allows them to survive in harsh environments. The most common stress factors they have to deal with are: heat, cold, acidity, NaCl and high hydrostatic pressure (HHP). Their ability to survive depends on their skills to cope with stress factors. Under stress conditions, LAB activate mechanisms that allow them to adjust to the new conditions, which can influence their viability and technological properties. This ability to adapt to different stress conditions may come from the cross-protection systems they have, as resistance to one factor may help them to deal with the other stress effectors. LAB are highly valuable for the food industry and that is why it is important to understand their stress response mechanisms.

Opis:
To develop a protein rich sorghum weaning food in a country with high poverty rate, the effects of adding soybeans and tiger-nut, two different ratios was formulated, R1 and R2. R1 was formulated in the ratio 5:3:2 (comprising of 50% sorghum, 30% soybean and 20% tiger nut flours) while R2 was formulated in the ratios 4:4:2 (40% sorghum, 40% soybeans and 20% tiger nut flours), respectively. Two fermentation processes was done for the ratios, starter (single) base fermentation ratios (SBFR) and spontaneous fermentation ratios (SPFR). Microbial analysis (total bacteria, yeast count, lactic acid bacteria count and enteric bacteria counts) were done after every 6 hrs of fermentation. The highest total bacterial count obtained was (4.4×105) in SPFR2 while the lowest count was 2.4×102 in SBFR1. Lactic acid bacteria range from 6.2×105 to 1.0×103. The highest enteric bacteria count was observed in SPFR1 (9.0×104) while highest yeast count (1.3×105) was observed in SPFR2. No growths were recorded for yeast and enteric bacteria after 12 to 24 hrs of fermentation for the starter based products. The results showed that the overall nutritional quality of sample SBFR1 was superior than sample SBFR2. Sample SBFR1 and had the higher total energy, protein content and reasonable amount of carbohydrates. The fermentation improves the nutritional qualities of locally produced sorghum weaning foods. Fortification of these foods with soybeans and tiger nut can be an added advantage as this may likely be a remedy to solving the menace of protein energy mal-nutrition in the developing countries and it was also confirmed that lactic acid bacteria used as starter, control the growth of yeast and enteric bacteria there by increasing the safety and shelf life of the product.

Opis:
This study aims to see the condition of hematocrit levels and differential leukosit after immersion in LAB isolated and after in vivo, using Aeromonas hydrophila bacterium. LAB isolated were obtained from the organs of the common carp intestine. The study used a Completely Randomized Design (RAL) consisting of four treatments and three replications. The treatment used was immersion of test fish for 24 hours in several isolates of LAB with a density of 108, namely A: without LAB isolate (control), B: isolate CcB7, C: isolate CcB8, D: isolate CcB15. Immersion was done three times, with a frequency of seven days. Parameters observed included hematocrit levels, leukocyte differentiation and survival rate. The results showed that immersion in LAB isolate CcB15 will enhance the differential leukocytes and hematocrit levels that serve as indicators of carp body resistance, which is shown by high levels of white and red blood cells.
