On the growth of Brucella species in the presence of erythritol in defined and undefined media and the amniotic fluid of human, cow, and sheep

On the growth of Brucella species in the presence of erythritol in defined and undefined media and the amniotic fluid of human, cow, and sheep. Tripathi, K. K.; Bhatnagar, L.; Seiffge, D.; Jankowski, R. P.; Aikins, H. E.; Gupta, K. G. (Dep. Microbiol., Panjab Univ., Chandigarh, India). Zentralbl. Bakteriol., Parasitenkd., Infektionskr. Hyg., Abt. 1: Orig., Reihe A, 237(2-3), 324-9 (English) 1977. CODEN: ZMMPAO. DOCUMENT TYPE: Journal CA Section: 3 (Biochemical Interactions) The addn. of erythritol [149-32-6] to defined medium enhanced the growth of the majority of B. abortus and B. melitensis strains tested, but the stimulatory effects of erythritol were less marked and more variable in undefined media (glycerol dextrose broth and tryptose broth). In addn., nearly 90% of the aminotic fluid samples from humans showed antibrucella activity, whereas amniotic fluid from cows and sheep bud no antibrucella activity. Therefore, the protection of humans (but not other animals) from abortion due to Brucella may be due to the absence of erythritol from human tissues and (or) to the antibrucella activity of human amniotic fluids.

Effect of polyols on the corrosion of aluminum in warm basic solutions

Effect of polyols on the corrosion of aluminum in warm basic solutions. Hajika, Toshiaki; Watanabe, Masahide; Hayakawa, Yasumasa (Yamanashi Univ., Kofu, Japan). Aruminyumu Hyomen Shori Kenkyu Chosa Hokoku, 80, 10 (Japanese) 1974. CODEN: AHSHDT. DOCUMENT TYPE: Journal CA Section: 56 (Nonferrous Metals and Alloys) In degreasing of Al in an alk. soln., corrosion was severe and was inhibited by adding. a polyol. The effectiveness decreased with increasing pH and temp., but increased with increasing amt. of hexahydroxy alc. The inhibition increases with increasing OH-no. in 2-6 OH-contg. polyols. Sorbitol [50-70-4] and mannitol [69-65-8] had better inhibition than glycerol [56-81-5], ethylene glycol [107-21-1], and erthritol [149-32-6].
