หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Decolorization of Biogas Effluent from Palm Oil Mill Using Combined Biological and Physical Methods) ผู้เขียน:Surasak Bunrung, Suteera Prasertsan, Poonsuk Prasertsan สื่อสิ่งพิมพ์:pdf AbstractTwo mixed cultures (Super LDD.1 and Super LDD.2) were used as inocula (10%) for the decolorization and treatment of biogas effluent from palm oil mill (BEPOM) under aerobic (2.5 volume of air per volume of medium per minute, vvm) and microaerobic conditions, respectively. With the supplementation of 10% palm oil mill effluent (POME) as nutrients, Super LDD.1 and Super LDD.2 showed higher decolorization than the Super EM culture under microaerobic conditions after 4 d cultivation. The optimum inoculum size for both sources was 20% (volume per volume) and Super LDD.1 produced higher decolorization (27.0%) and phenol removal (20.4%) than Super LDD.2 (16.7% and 12.1%, respectively) after 2 d cultivation. However, Super LDD.1 exhibited slightly lower chemical oxygen demand (COD) removal than Super LDD.2 (27.8% and 29.2%, respectively) after 6 d cultivation. The effluent after treatment by Super LDD.1 was subsequently tested for the effect of pH and palm ash concentration (1–15%, weight per volume) under mixing conditions (on 125 rpm shaker) at room temperature (30 ? 3 ?C) for 1 h. The highest decolorization (84.7%), phenol removal (90.8%) and COD removal (88.9%) were achieved at 15% (w/v) palm ash. The results indicated the potential treatment of BEPOM using a biological method (Super LDD.1 culture) in combination with a physical method (palm ash) which was better than using each treatment alone. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effects of Extender and Storage Time on Motility and Ultrastructure of Cooled-Preserved Boar Spermatozoa) ผู้เขียน:Duangjai Boonkusol, Kulnasan Saikhun, Poonsuk Ratanaphumma สื่อสิ่งพิมพ์:pdf AbstractArtificial insemination (AI) using fresh diluted semen is used worldwide in the porcine industry. Viability of spermatozoa in diluted semen depends on several factors, such as the interaction with the type of extender and storage duration. The aim of this study was to evaluate the effects of extenders and storage time on the motility and ultrastructure of cooled-preserved boar spermatozoa. Semen samples were collected, diluted in BTS, Merck III or Androhep and stored at 15?C for 0, 1, 3, 5 and 7 d. The samples were warmed (37?C) and spermatozoa were evaluated for motility using light microscopy and ultrastructure using scanning (SEM) and transmission (TEM) electron microscopy. The results showed that motility did not differ significantly (P>0.05) among extenders at days 0 to 3, while Androhep showed a significantly (P<0.05) higher percentage of motility than BTS and Merck III from days 5 to 7. At day 7 of semen storage, plasma and acrosomal membrane damage were observed, as revealed by SEM and TEM. These findings suggest that the type of semen extender and cooled-preserved time affected motility and caused structural damage to boar spermatozoa, especially in the plasma and acrosomal membrane. |
