Morphological, cultural, physiological and biochemical characteristics were employed to identify lactic acid bacteria (LAB), isolated from drinking yoghurt in different areas in Fars province, Iran. From 18 drinking yoghurt samples a total of 673 LAB positives were determined, in which 117 (17.38%) and 556 (82.62%) were identified as lactic acid cocci and lactic acid bacilli, respectively. Addi...
introduction ensiling is one of the common preserving methods for forage or other organic materials. in this method, organic matters were preserved by proving an aerobic condition and then by reducing the ph with increasing acids production (mainly lactic acid). some circumstances like enough soluble carbohydrates, low buffering capacity and appropriate dry matter concentration are needed in en...
In this protocol, 3-(2-carboxybenzoyl)-1-methyl-1H-imidazol-3-ium chloride [Cbmim]Cl and sulfonic acid functionalized pyridinium chloride [pyridine-SO3H]Cl as a new, reusable, and green Brønsted acidic ionic liquid (BAIL) catalyst were synthesized and successfully used for the one-pot ring opening of epoxide with sodium azide (NaN3) in water at room temperature. Epoxides under ring-opening easi...
objective: this study aimed to assess the destructive effects of citric acid, lactic acid and acetic acid produced from the fermentation of foods on primary teeth enamel. methods: this in vitro, experimental study was conducted on 24 sound primary teeth. the teeth were polished with a fine abrasive paper under running water. tooth pieces measuring 3 × 4 × 3mm were cut out of the teeth and sto...
This experiment was conducted to determine the performance and intestinal microflora population of broiler chicks in diets supplemented with Roxarsone, Avilamycin and Formycin gold during starter period. A basal diet was formulated according to NRC (1994) recommendation for starter (0-21 d) period and also supplemented with appropriate amounts of the mentioned growth promoters. Each of the tr...
The aim of the present study was to investigate the effect of Lactococcus lactis and Weissella cibaria probiotics on growth performance, intestinal bacterial flora, digestive enzymes and intestinal histology in common carp (Cyprinus carpio). Fish with an average initial weight of 17 g were divided into 10 treatments with 3 replications. Fish food in treatments 1, 2 and 3 were supplemented with ...
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
lactobacillus strains are a major part of the probiotics, microflora of the intestine and of fermented dairy products, and are found in a variety of environments. the aim of this study was to find out the ability of bile and acid tolerance and antibacterial properties of the twenty eight isolates of three group lactobacilli namely lactobacillus plantarum, lactobacillus casei and lactobacillus d...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
BACKGROUND Bioplastics, like polylactic acid (PLA), are renewable alternatives for petroleum-based plastics. Lactic acid, the monomer of PLA, has traditionally been produced biotechnologically with bacteria. With genetic engineering, yeast have the potential to replace bacteria in biotechnological lactic acid production, with the benefits of being acid tolerant and having simple nutritional req...
