In composting, the degradation of lignocellulose in straw is problematic due to its complex structures such as lignin. A common solution to this problem is the addition of exogenous inoculants. AC-1, a stable thermophilic microbial composite, was isolated from high temperature compost samples that can decompose lignocellulose at 50–70 °C. AC-1 had a best degradation efficiency of rice straw at 60 °C (78.92%), of hemicellulose, cellulose and lignin were 82.49%, 97.20% and 20.12%, respectively. It showed degrad-ability on both simple (filter paper, absorbent cotton) and complex (rice straw) cellulose materials. It produced acetic and formic acid during decomposition process and the pH had a trend of first downward then upward. High throughput sequencing revealed the main bacterial components of AC-1 were Tepidimicrobium, Haloplasma, norank-f-Limnochordaceae, Ruminiclostridium and Rhodothermus which provides major theoretical basis for further application of AC-1.

Ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO) genes play important roles in CO2 fixation and redox balancing in photosynthetic bacteria. In the present study, the kefir yeast Kluyveromyces marxianus 4G5 was used as host for the transformation of form I and form II RubisCO genes derived from the nonsulfur purple bacterium Rhodopseudomonas palustris using the Promoter-based Gene Assembly and Simultaneous Overexpression (PGASO) method. Hungateiclostridium thermocellum ATCC 27405, a well-known bacterium for its efficient solubilization of recalcitrant lignocellulosic biomass, was used to degrade Napier grass and rice straw to generate soluble fermentable sugars. The resultant Napier grass and rice straw broths were used as growth media for the engineered K. marxianus. In the dual microbial system, H. thermocellum degraded the biomass feedstock to produce both C5 and C6 sugars. As the bacterium only used hexose sugars, the remaining pentose sugars could be metabolized by K. marxianus to produce ethanol. The transformant RubisCO K. marxianus strains grew well in hydrolyzed Napier grass and rice straw broths and produced bioethanol more efficiently than the wild type. Therefore, these engineered K. marxianus strains could be used with H. thermocellum in a bacterium-yeast coculture system for ethanol production directly from biomass feedstocks.

The main purpose for the application of science and technology for livestock group of cow, is to form a group of skilled and professional livestock, as vaccinators, can take advantage of Azadirachta indica leaves a plant insecticide, apply a good cage sanitation, can produce organic fertilizer from feces of cow, can treat hay as feed to good nutritional value. The method used is education and training. Activity results obtained, that 10 percent of members of the group have managed to become vaccinators cadres, able to implement good sanitation stables, feces of cow (Stomoxys calsitrans) can process technology with EM4 into organic fertilizer and can process the rice straw with urea spraying method, to produce feed hay to the value of good nutrition for growing cattle.

Ingestive Behaviour

This study was undertaken to find ways of reducing the time taken by goats tobegin to eat an edible feed that they have not previously encountered. Experiment 1demonstrated that the time taken for goats (7-8 months old) to ingest an unfamiliar feed(rice straw) was shorter (4 days) when it was first offered to them in the presence offamiliar positive cues (the odor or flavor of juices extracted from previously eaten,nutritionally beneficial grasses), than if it was offered in the absence of such cues (10 days).In contrast, when the feed was offered in the presence of the odor of parasitised goat feces,the time to first ingestion was extended to 20 days. Experiment 2 showed that when sixmonthold goats were exposed to feeds they had not experienced previously (rice straw orrice bran) they did not ingest these feeds in less than 7 days. However, they commencedingesting these feeds immediately if they had been exposed to them, prior to weaning, inthe presence of their mother or another adult goat. Application of the principles of feedingbehavior, as illustrated by the present studies, to goats in Vietnam may improve theirproduction, especially when diets are changed frequently and include both familiar andunfamiliar materials.Keywords: Behavior; Diet selection; Flavor; Neophobia; Social facilitation; Goat.

The activities conducted in Maros regency Tanralili district Purnakarya village in chickens and beef cattle groups Cedde Jaya. The main source of livestock feed cows during the dry season are dry forage, rice straw, corn straw and hay crops of nuts which happened to be planted at the time of drought. Besides, leaf  Gamal is also a main feed in dry  season. Number of cattle per family ownership only 2-3  head extensively maintained. Range chicken as well as extensive maintenance, ownership on average 2-5 chicken each household group.  To increase the productivity of cattle, the team provides counseling, coaching, training and mentoring as well as providing some main of facilities such as cattle shed, biogas digester, planting banana. Results are expected in the presence of  activities is the avaibility of green forage mainly during the dry season, so that the cattle population will increase, the biogas as a fuel  alternative to kerosin and LPG gas, liquid and solid fertilizer from biogas by-product process, the increasing population of chicken qualified (meat and eggs as well as the day old chick).  Besides the problem of production is also done on the farm management. The activities is expected that will increase the incomes of farmers further improve the welfare of Maros regency. For the sustainability of the program it is necessary supervision and guidance are routinely performed by the related department along with the college.

Objective: ZnO nanoparticles were synthesized using wet impregnation method, and activated carbon from rice straw (RS) prepared through chemical route. Methods: The nano-composites ZnO-AC series were prepared with different ZnO:AC ratio of 10, 20, 50, and 70% to optimize the zinc oxide nanoparticles used. The obtained composites were characterized by FE-SEM, XRD, SBET, and optical techniques then used for the photo-degradation of Malachite green dye (MG) under visible light. Results: It was found that 10ZnO-AC exhibited excellent visible light photo-catalytic performance. The ·OH radicals’ formation is matching with photo-activity of the prepared composites. The photo-degradation efficiency of MG increased from 63% to 93%, when the 10ZnO-AC photocatalyst amount was increased from 0.5 to 6 g/L. Conclusion: The GC-MS technique was used to analyze the intermediates formed; up to 15 kinds of chemicals were identified as the degradation products.
