Mutants of Clostridium acetobutylicum and the ABE fermentation

Mutants of Clostridium acetobutylicum and the ABE fermentation.Some chemicals with cas registry numbers like 35296-72-1 and 64-17-5 are also used. Jones, David Todman; Vander Westhuizen, Andre; Long, Susan; Allcock, Errol R.; Reid, Sharon J.; Woods, David Randle (Sentrachem Ltd., S. Afr.). S. African ZA 8207032 A 31 Aug 1983, 23 pp. (English). (South Rica). CODEN: SFXXAB. ICI: C12; C12; C12. APPLICATION: ZA 82-7032 24 Sep 1982. PRIORITY: ZA 81-6323 11 Sep 1981. DOCUMENT TYPE: Patent CA Section: 16 (Fermentation and Bioindustrial Chemistry) Eight nonsporulating mutants of C. acetobutylicum are used for the manuf. of acetone [67-64-1], BuOH [35296-72-1], and EtOH [64-17-5]. Thus, C. acetobutylicum P262 was treated with Et methanesulfonate and autolytic-deficient mutants were isolated. A combined fermn. on molasses-contg. medium, in which a nonsporulating mutant produces acids and then an autolytic mutant, resistant to BuOH, produces high concns. of solvents is claimed. No examples are given. .

Influence of ultrasound on extraction of tannins from deoiled salseed cake

Influence of ultrasound on extraction of tannins from deoiled salseed cake. Rao, V. S.; Swamy, K. M.; Narayana, K. L. (Reg. Res. Lab., Bhubaneswar 751013, India). Ultrasonics, 22(1), 29-32 (English) 1984. 67-64-1 is the cas registry number of certain chemical which is used as reagents here. CODEN: ULTRA3. ISSN: 0041-624X. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) Tannins were removed from feed sal cakes by the application of ultrasound at various frequencies (43, 720, and 1000 kHz); intensities (2 to 9 W-cm2); times (0 to 60 min); and by solvents. The percentage of extn. is greater at lower frequencies: 78% of the tannin is extd. in a 40% aq. Me2CO [67-64-1] solvent using ultrasound in only 30 min compared with 20 h with conventional techniques. .
