The question of the collisional production of the β meteoroids is reexamined incorporating recent experimental results (A. Fugiwara, G. Kamimoto, A. Tsukamoto, 1977, Icarus31, 277–288). The collisional model yields a flux of fragments supported by the conservation of mass flux which does not account by far for the observed flux of submicron grains. Particles larger than Barbour Femme Ebay about 100 μm will be destroyed by collisions inside 1 AU, well before they can get near the Sun. The existence of two independent populations of interplanetary dust grains as proposed by L. B. Le Sergeant and Ph. L. Lamy (1978, Nature266, 822–824; 1980, Icarus43, 350–372) appears reinforced. It is proposed that the bulk of submicron grains does not necessarily travel in hyperbolic orbits and that β meteoroids may be Barbour Soldes a phenomenon—possibly Barbour Sale transitory—of limited importance.
The sugars in extracts of dates (Phoenix dactylifera) were converted into ethanol by S. cerevisiae. At an initial cell concentration of 10 g l−1 in a batch process, fermentation of juice with 98 g l−1 sugars (49.5 g l−1 glucose and 48.5 g l−1 fructose) was completed in 12 h, and in 20 h with 138.3 g l−1 sugars. With the membrane recycle bioreactor, with a cell density of 150 g l−1, maximum productivity with complete sugar utilization was 25 g l−1 h−1 with an ethanol concentration of 68 g l−1. This is more than eight times better than the batch process. The subsequent production of acetic acid from the fermented date juice was conducted with Acetobacter aceti. In a membrane recycle bioreactor, productivity was 10.8 g l−1 h−1 at an acetic acid concentration of 45 g l−1. This is more than 20 times higher than that of a batch process.
