Most of ethanol production processes are limited by low ethanol production rate and recyclable problem of ethanologenic organisms. In the present study Saccharomyces cerevisiae TISTR 5339 entrapped in an aqueous mixture of alginate and pretreated-bagasse was used for ethanol production of immobilization parameter of yeast cells consisting of amount of bagasse and alginate concentration on ethanol production were investigated. The results showed that increase in alginate concentration and the amount of bagasse can increase structural strength and reduce deterioration of bead. The optimal condition of immobilization was 1.0% (w/v) bagasse and 2.5% alginate. Ethanol yield (Yp/s) ethanol production rate (Qp) and efficiency of fermentation (Ey) obtained from the bagasse-alginate immobilized yeast cell was 3.39±0.72 g/l0.14±0.03 g/l/h and 70.98±14.08% respectively. The ultrastructure obtained from SEM illustrated that S. cerevisiae TISTR 5339 was well incorporated within the bagasse-alginate matrix. Moreover the bagasse-alginate immobilized yeast cells were reusable at least 5 times with Ey higher than 50% of 1st round of fermentation. Therefore the pretreated bagasse-alginate immobilized yeast cells is an alternatively interesting techniques with effiiciency for ethanol production in the future.

The purpose of this research was to develop bagasse packaging antagonizing fungi with turmeric extract for Green Cos Lettuce cultivation. The bagasse package would incorporated with fungistatic turmeric extract instead of using chemicals at concentrations 0 5000 10000 15000 and 20000 ppm. The packaging characteristics efficiency of turmeric extract and the growth of Green Cos Lettuce determined into the percentage of germination height measurement fungi contamination characteristic were tested under the presence and absent antifungal bagasse The plant seedling spreading onto the surface of the packaging with turmeric extracts could be excelled for -their growth with the induction of germination rate of 92-97 percentages. Turmeric extracts at concentrations of 15000 and 20000 ppm had also expel the emergence of Penicillum sp. inhibit Rhizopus sp. and slow down Colletotrichum sp. Moreover the turmeric extract caused packaging decaying by itself slowly possibly helping in common airborne mold prevention. This green safe material showed the respectably effective for Green Cos Lettuce seedling especially for the fungal pathogen contamination during implantations. This research based on using natural extracts and natural fibers from agricultural waste is thus being ecofriendly nonchemical application of packaging product with easily digested for decent consumers who love their health and care environment.

The current time activated Carbon spaciously have been used in the process of wastewater Treatment and Air Pollution Treatment because of it can absorb various materials such as colors smells and organic materials both in the wastewater or air pollution In this research the researcher interest to study the activated carbon from bagasse as become more quantity in the country to use for reducing the pollution of wastewater at Sugar Company and recycling the leaving materials. This study is the Experimental Research being divided into 2 kinds of charcoal: 1) synthesizing activated carbon from bagasse 2) charcoal. The three contents of waste water: 10 50 and 100 percent are used for analyzing and testing at three periods of time: 30 60 and 90 minutes. The example of the wastewater were analyzed the color and COD. The using activated carbon from the bagasse with the content of wastewater at 10% shown that it could not absorb the color differently at every periods of time the color remained lower than 5 Pt-Co and it could reduce more COD at the more periods of time. At the content of waste water 50% shown that the more using time for absorbing the color the quality of absorbing become lower (10 15 and 20 Pt-Co) but it became more reduce COD while the absorbing the color at the content of waste water 100% found that when used the more time quality of absorbing the color became lower (25 30 and 35) while the quality of reducing the COD became increase. The charcoal at the content of wastewater 10% its’ absorbing color was 5 Pt-Co at the all periods of time but the result of reducing the COD was increase: 4300 4000 and 3800 respectively. As the testing the content of waste water at 50% shown that the more using the time its’ quality of absorbing the color became lower while the quality of reducing the COD became decrease: 7330 6500 and 6030 respectively. As studying the content of waste water 100% found that the more using the time for treatment the waste water its’ quality became decrease but it could more reduced COD. The comparison between the activated carbon from bagasse and the charcoal shown that the activated carbon from bagasse can absorb the color better than the charcoal at 0.25 Pt-Co and could more reduce COD than the charcoal 43.5 % by average at the content of waste water 10%. While the waste water 50% the activated carbon from bagasse could more absorb the color than the charcoal at 55% and can more reduced the COD than the charcoal 19.34% averagely. For the content of waste water 100 % the activate carbon from bagasse could more absorb the color than the charcoal at 54.17% and reduced the COD 7.83% by averaging.

Natural compost or organic fertilizers suitably applied to soil since it improves soil quality is cheap and easy to manage and has no pollution residues. However the right ratio of ingredienttypes as well as enough fermentation period have to be tested in order to obtain suitable fertilizer for each particular plant species. In this study researchers have conducted experimental fermentation of organic composts composed of various ratios of either residues of bagasse or banana pulp mixed with sludge. This organic compost performs as organic fertilizer adding nutrients to the sludge since the sewage sludge by itself can only help improve soil structure but has insufficient nutrients for the growth of plants. The sludge in the experiment was obtained from sewage sludge at WatSuanKaew Nonthaburi province. The results of the organic compost after fermented 49 days showed that the compost turned to brown and black and most plant materials were already macerated. The compost of sewage sludge mixed with banana pulp in the ratio of both 0.75 to 5.0 and 1.0 9 to 5.0 yielded the best growth of the morning glory. Both formulas accelerated the growth of seedlings of the plant to a high average of 15.0 ± 0.3 cm after grown for14 days. The concentration of main nutrients was also close to the values specified by the standard compost. This banana pulp compost with pH 7-9 helpedreduce the acidity in the soil. While organic fertilizer derived from sewage sludge mixed with bagasse could only help accelerate the growth of the seedlings but did not accelerate the proliferation of immature plants. Additionally the ratios of carbon to nitrogen in all bagasse composting samples were more inflated whereas the nitrogen phosphorus and potassium were under the specified standard. This bagasse caused lower pH to 5.0-6.0 contributing more acidic to soil. From all results of these findings the organic compost from the fermentation of banana leafs was therefore appropriated for improving soil quality by mixing with sludge. The organic compost provided enough major and minor nutrients that stimulated the plant growth as well. However the formulated ratio of the bananas leafs and sludge mixtures needed to be prior experimentally tested.

This research studies the potential for using waste ash from industrial and agricultural by–products as a geopolymer material. This paper presents a study of the resistance to chloride penetration and resistance to sulfuric acid of geopolymer mortar containing ground rice husk ash (RA) and ground bagasse ash (BA). Geopolymer mortars with constant liquid to ash ratio and similar flow were used for the tests. Compressive strength porosity chloride penetration test Rapid migration test of chloride depth chloride ion diffusion coefficient immersion test of chloride depth and weight loss with impressed sulfuric acid were investigated. Test results show that the workable flow of geopolymer mortar was in the range of 110–115% and was dependent on the ratio by mass of sodium silicate to NaOH and the concentration of NaOH. Extra water was used to improve the workabililty. In case of rice husk ash geopolymer mortar the geopolymer mortars with high strengths were obtained with concentration of NaOH of 15M with the sodium silicate to NaOH ratio by weight of 2.5. However the bagasee ash geopolymer mortars with high strengths were obtained with concentration of NaOH of 10M with the sodium silicate to NaOH ratio by weight of 2.5. The use of rice husk ash and bagasse ash produces geopolymer mixes with good strength and resistance to acid and chloride penetration. The resistance to acid and chloride penetration is higher with an increase in the sodium silicate to NaOH ratio by weight of 2.5.
