many organisms produce lactic acid by fermentation, but most industrially important strains are from the genus lactobacillus and rhizopus oryzae. l(+)-lactic acid is the only optical isomer for use in pharmaceutical and food industries because human body is only adapted to assimilate this form. in this research, six strains of lactobacillus and four strains of r. oryzae (known as high producer)...

lactobacillus spp are a group of gram-positive, non-spore forming, cocci or rod shaped, catalase negative organisms that benefit to the host. prebiotics are non-digestible food ingredients that stimulate the growth and /or activity of bacteria in the digestive system in ways claimed to be beneficial to health. this study was conducted in order to investigate the effects of selected probiotic mi...

This study was carried out to reduce Byssochlamys fulva PTCC 5062 in lime juice. The main and interaction effects of pH (3.5 4.5) voltage gradient (15 20 V/cm) were investigated on mold inactivation during ohmic heating at 88, 93, 98°C. results showed that had significant Dvalue Zvalue (p<0.01). In order model the survival behavior fulva 5062, due nonlinearity c...

The efficacy of the topoisomerase I inhibitor 7-ethyl-10-(4-[1-piperidino]-1-piperidino)-carbonyloxy-camptotheci n (irinotecan, CPT-11) has been examined against a panel of six independently derived neuroblastoma xenografts. Intensive courses of therapy, where irinotecan was administered i.v. daily 5 days per week for two consecutive weeks [(dx5)2; defined as 1 cycle], were compared to more pro...

Given the growing interest in the production of new and low cost bioemulsifiers, the rice and wheat bran and straw were investigated in this study for the production of bioemulsifier by Lactobacillus plantarum subsp. plantarum PTCC 1896 (probiotic). The strain produced bioemulsifier only in the rice bran hydrolysate medium. The bioemulsifier amount reached around 0.7 g L for 72 hours of ferment...

The ability of Lactobacillus acidophilus LA-5, Bifidobacterium lactis BB-12, delbrueckii subsp. bulgaricus PTCC 1737 and Streptococcus thermophilus 1738 in removing Benzo(a)pyrene (BaP), Benz(a)anthracene (BaA), Chrysene (Chr) Benzo(b)fluoranthene (BbF) from contaminated aqueous solution with respect to strain types, time temperature incubation was studied. results showed that BaA, Chr, BbF BaP...
