 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Physiological Study and Alcohol Oxidase Gene(s) of Thermotolerant Methylotrophic Yeasts Isolated in Thailand) ผู้เขียน:ดร.นันทนา สีสุข, รองศาสตราจารย์ , ดร.สาวิตรี ลิ่มทอง, ศาสตราจารย์ , Hiroya Yurimoto, Yasuyoshi Sakai, Nobuo Kato สื่อสิ่งพิมพ์:pdf AbstractTwo thermotolerant methylotrophic yeasts, Candida sithepensis sp. nov. and Pichia siamensis sp. nov. isolated in Thailand were studied for their physiology and alcohol oxidase gene(s). Optimum and maximum temperatures for growth on methanol of C. sithepensis sp. nov. were 34?C and 37?C whereas those of P. siamensis sp. nov. were 37?C and 40?C, respectively. Effect of methanol on the methylotrophic growth of the two yeast strains was investigated within the ranges of 0.25% to 2% (v/v) methanol. At 34?C, C. sithepensis sp. nov. exhibited a decline in ?max from 0.16 h-1 to 0.13 h-1 with respect to increase in methanol concentration. When cultivated at 37?C, the ?max of C. sithepensis sp. nov. was found to be drastically decreased from 0.16 h-1 to 0.10 h-1 within the same ranges of methanol concentration studied. P. siamensis sp. nov. showed an insignificant decrease of ?max with respect to an increase in methanol supplement when cultivated at 37?C. Key enzymes involved in methanol dissimilatory pathway, i.e., alcohol oxidase (AOD), glutathione-dependent formaldehyde dehydrogenase (FLD), formate dehydrogenase (FDH) and catalase (CAT) of the two yeasts were assessed. As for the favorable growth of C. sithepensis sp. nov. at its optimum temperature, fairly high level of specific AOD activity was observed but lower level of specific AOD activity was exhibited at maximum temperature. In contrast, specific FLD and FDH activity profiles were found to be higher when the yeast C. sithepensis sp. nov. was grown at its maximum temperature compared to the methylotrophic growth at its optimum temperature. Catalase production appeared to be slightly disturbed under all conditions studied. In case of P. siamensis sp. nov., stationary phase growth under low methanol supplement at its optimum temperature appeared soon after 24h cultivation. Nucleotide sequences of AOD gene(s) of the two yeasts were investigated. C. sithepensis sp. nov. showed two AOD genes designated as AOD1 and AOD2 whereas P. siamensis sp. nov. revealed only one AOD gene within the genome. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : High-Temperature L-Lactic Acid Fermentation of Food Waste Under Open Condition and Its FISH Analysis of Its Micro Flora) ผู้เขียน:Kenji Sakai, Yutaka Ezaki, Saowanit Tongpim, ดร.วิเชียร กิจปรีชาวนิช, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractWhen minced model kitchen refuse was inoculated with Bacillus coagulans and incubated under non-sterilizing open condition, at the temperature below 45?C, racemic mixture of D-and L-lactic acid was found, while L-lactic acid was selectively accumulated at 50-65?C. To analyze microflora of such mixed culture system, whole cells (fluorescent in situ hybridization) using species and group of specific 16S rRNA-targeted oligonucleotide probes (16S-FISH) was applied. As a result, predominancy of mesophilic lactic acid bacteria at lower temperature, and of Bacillus coagulans at higher temperature was confirmed. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Seasonal Changes of Wood Formation and some Characteristics of Heartwood Formation in Teak (Tectona grandis L.) Plantation) ผู้เขียน:Tadashi Nobuchi, Sirirat Janmahasatien, Masaharu Sakai สื่อสิ่งพิมพ์:pdf AbstractSome fundamental investigations of wood and heartwood in plantation grown teak (Tectona grandis L.) were carried out. In order to verify the relationship between wood formation and growing conditions, moisture content of soil and the development of leaves were also studied. It was found that moisture content of soil was higher in the rainy season. Since trees started budding in May which was the beginning of the rainy season, those trees grown at the foot of the hill showed earlier development of leaves. As for the time sequence of wood formation using the pining method, it was revealed that wood formation started after the budding and continued to do so until the end of rainy season. Parenchyma cells of the outer sapwood had great amount of starch grains as reserve substances and this amount abruptly decreased in the middle and inner part of sapwood. Parallel with the decrease of starch grain, lipid droplets increased. However, in the heartwood, both parenchyma cell and wood fibers contained lipid droplets. Elemental analysis of the black substance in the outer heartwood was tried by SEM-EDXA method and it was revealed that no special element was contributed to the black streak of heartwood. |
