Changes In Microbiological, Physicochemical, Biochemical And Therapeutical Characteristics Of Yoghurt Upon The Addition Of Selected Medicinal Herbs., Afsaneh Najarian
Student Works (2010-2019)
The effects of herbs on the changes in probiotic growth and metabolism in yoghurt during storage were studied. Angelica sinensis, Codonopsis pilosula, Illicium verum, Lycium barbarum, Momorsdica grosvenori and Psidium gujava water-extracts were co-incubated with pasteurized full cream milk containing Lactobacillus acidophilus, Bifidobacterium, Streptococcus thermophilus and L.casei as starter culture. The addition of herbal water extracts stimulated Lactobacillus sp. growth in P. guajava–yoghurt (126.3±26.3 × 106 CFUml-1) only on day 0 and in L. barbarum–yoghurt from 0 to 3 days (109.3±21.5 to 112.7±28.8×106 CFUml-1 respectively) of refrigerated storage. The growth of S. thermophilus were recorded higher than plain yoghurt for …

Related Enzymatic Activities In Solid-Substrate Fermentation Of Sago Hampas With Pycnoporus Sanguineus, Rifat Ara Matta
Student Works (2000-2009)
Solid substrate fermentation (SSF) of sago pith residue known as 'hampas' with Pycnoporus sanguineus for enzyme production was carried out. Good growth of Pycnoporus sanguineus in SSF was noted on 'hampas' supplemented with 0.38% urea, 0.2% KH₂PO₄ and 0.05% MgSO₄·7H₂O over a period of 30 days. Xylanase, lignin peroxidase and laccase activities were detected in Pycnoporus sanguineus cultures. Maximum xylanase and laccase activities of 5.26U/g of substrate on day 10 of SSF and 14.35U/g on day 15 of SSF of substrate were obtained respectively. The lignin peroxidase activity was less pronounced with an activity of 1.31 U/g of substrate on …
