Nhựa sinh học Polyhydroxyalkanoate (PHA) là loại nhựa do vi vật tổng hợp nên trong điều kiện dư thừa nguồn cacbon. Có nhiều có thể PHA, đó các loài chịu mặn như Bacillus, Halomonas... Tuy nhiên, thuộc vùng đảo Trường Sa chưa được quan tâm nghiên cứu. Nghiên cứu này trình bày một số kết quả phân lập và đánh giá khả năng PHA của chủng từ quần Sa. Trong 21 khuẩn TSLT21 tới 30,9% khối tế bào khô đế...

Endoglucanase is an important enzyme participating in the hydrolysis of cellulose into oligosaccharides or glucoses can be used a variety industrial fields. A gene (code GL0183420 designated as eg9) 1398 bp encoding for endoglucanase family GH8 was identified from metagenomic DNA data bacteria humus surrounding wood hydrolyzed by white rot fungi. The 126 terminal nucleotides at 5' encode signal...

Lipase is an enzyme that can be applied in many industrial fields so it has a good economic prospects. The demand for lipase was still unfulfilled at the time this article written. character of needs are vary depending on industry which used. Temperature and pH two factors most influence activity. This reports bacteria isolated from coconut, avocado, tempeh, areca nut their lipolytic activity 7...

Multistage type cold storage is a refrigeration machine required in an industry because it functions to store food products for long time. Bali, as world tourist destination, will rely heavily on this cooling system preparing services tourists, especially the and beverage sector. designed reach evaporator temperature below -30oC thus used compressor performance must be able produce maximum effe...

In this study, it was aimed to investigate that the effect of drying process on rainbow trout (Oncorhynchus mykiss Walbaum, 1792) roes in terms proximate composition, aw, pH, TVB-N, TBARs, microbiological counts and color parameters. Drying lasted 42 hours including, 18 at 30oC 24 45oC. The dried fish were vacuum-packed (vacuum degree 0.02MPa) stored 4oC for 90th days. crude lipid, protein, ash...

Microalgae are known to be a nutrient-rich feed source for many aquatic animals. It is also an important raw material exploit high biological activity substances humans. This the first study on characteristics and algae biomass production from green microalgae Nannochloris atomus being carried out in Vietnam. In this study, scientific name of strain N. NT12 based morphological 18S rRNA gene seq...

the aim of this study was to degrade furfural by a new nanotube system. to degrade some organic pollutants as well as to reduce the amount of furfural which is a well-known pollutant in oil industry, the photocatalytic process along with ultraviolet (uv) irradiation may be employed. in this study, the uv/tio2/pd system in which the nanoparticles of palladium doped into the titanium dioxide was ...

In this investigation is aimed at the removal of Astrazon Blue FGRL (AB FGRL) (basic dye) from an aqueous solution using waste clay (MC) obtained gold mine area. The natural was characterized and identified X-ray diffraction (XRD) analysis.Then, contact time, adsorbent dosage, pH, initial dye concentration temperature experiments were carried out in a batch system. efficiency found to be 97% pH...

In order to demonstrate filtration rate of edible cockle Cerastoderma edule under different salinity and temperature conditions, two groups namely healthy and parasited with Labratrema minimus (Bucephallidae; Digenea) were compared. Results showed that the parasited ones had difficulties in adaptation to the extreme conditions of salinity and temperature. Our results also showed that a healthy ...
