in the present study, the effects of milk supplementation on growth and viability of yogurt (streptococcus thermophilus and lactobacillus delbrueckii subsp. bulgaricus) and probiotic bacteria (lactobacillus acidophilus and bifidobacteria) were studied during yogurt production and 33 days of refrigerated storage. the incubation time to reach ph = 4.5 was greatly affected by the addition of milk ...

introduction: infertility is a common phenomenon in modern societies. today, use of assisted reproductive technologies (arts) for treatment of infertility is common, and cryopreservation is one of these technologies. cryopreservation has impact on the function and percentage of fertility of human sperm. in this study, motility, viability, nitric oxide, and dna apoptosis were assessed before and...

this research aimed to investigate the viability of probiotic bacteria ( lactobacillus acidophilus la-5 and bifidobacterium lactis bb-12) and yogurt bacteria ( streptococcus thermophilus and lactobacillus delbrueckii ssp. bulgaricus ) in yogurt during the fermentation, immediately after fermentation and during refrigerated storage (21 d, 4˚c). also the biochemical characteristics of milk as aff...

Cabbage is an economically important vegetable worldwide. Cabbage Fusarium Wilt (CFW) is a destructive disease that results in considerable yield and quality losses in cole crops. The use of CFW-resistant varieties is the most effective strategy to mitigate the effects of CFW. 01-20 is an elite cabbage line with desirable traits and a high combining ability, but it is highly susceptible to CFW....

Lipid transfer proteins (LTPs) are small secretory proteins in plants with defined lipid-binding structures for possible lipid exocytosis. Special groups of LTPs unique to the anther tapetum are abundant, but their functions are unclear. We studied a special group of LTPs, type III LTPs, in Arabidopsis (Arabidopsis thaliana). Their transcripts were restricted to the anther tapetum, with levels ...

A method for the preparation of developmentally staged microspores and young pollen from maize (Zea mays) has been devised. The preparations are of sufficient purity and quantity for biochemical analysis, including the analysis of steady-state protein and RNA populations associated with each stage. A major transition in protein populations occurs during the developmental period that encompasses...

7365AB, a recessive genetic male sterility system, is controlled by BnMs3 in Brassica napus, which encodes a Tic40 protein required for tapetum development. However, the role of BnMs3 in rapeseed anther development is still largely unclear. In this research, cytological analysis revealed that anther development of a Bnms3 mutant has defects in the transition of the tapetum to the secretory type...

background and objective: the current study was undertaken to check in vitro different characteristics of lactobacillus plantarum as potential probiotic. these characteristics include viability of probiotic and ph during cold storage, tolerance to acid and bile, and antibiotic resistance. material and methods: samples of yogurt were stored at 4°c and analyzed in time 0, 1, 3, 7, 10 and 14 days ...

the germination power of orchids (orchidaceae family) seems to betoo weak due lack of albumen. the study carried out with various treatments including pollination time and ga3 for breaking dormancy and increasing seed germination of orchids. the effect of pollination time (8 periods from january to august) and gibberellic acid (0, 500, 1000 and 1500 mg l-1) were studied on germination of phalae...
