SRC-4 starin is one of bacteria sellulose producing strains. It was obtained from the rottencoconut meat from Semplak, Bogor. The objective of this study is to obtain the optimumcomposition of modified HS medium to produce cellulose, by increasing yeast extractconcentration and also combination of carbon and vitamin sources. The production of celluloseby SRC-4 was done by 18 treatments on static culture. The increasing of yeast extractconcentration, combination of carbon and vitamin sources gave significant effect to theproduction of cellulose. The highest yield of cellulose was produced at the treatment consist of1.0 % yeat extract (as nitrogen source), 1 % glucose + 1 % glycerol (as carbon source) and0.164 ppm vitamin B1 + 0.020 ppm vitamin B2 (as vitamin source).

Изучена стойкость нутриентов молокосырья – белков, лактозы, витаминов С и группы В, используемого в производстве сывороточных напитков в присутствии приоритетных органических контаминантов – трихлорэтилена, хлороформа и дихлорэтана, которые обладают токсическим и канцерогенным действием и образуются при хлорировании в процессе водоподготовки в воде, применяемой для производства восстановленных и рекомбинированных молочных продуктов. Содержание белков, лактозы в восстановленной сыворотке определяли методом рефрактометрии; водорастворимых витаминов – методом капиллярного электрофореза; хлороформа, трихлорэтилена и дихлорэтана – методом газожидкостной хроматографии. Установлено, что хлороформ в воде не оказывает влияния на сохранность лактозы, белков и витаминов при приготовлении восстановленной сыворотки. Отмечено снижение содержания белков сыворотки, приготовленной на воде в присутствии трихлорэтилена и дихлорэтана, на 11%, лактозы – на 32% в сравнении с контрольными образцами, произведенными на воде без органических контаминантов. Содержание витаминов в восстановленной молочной сыворотке в присутствии трихлорэтилена снизилось: С – на 19%, В1 – на 28%, В2 – на 53%, В6 – на 8%; для дихлорэтана содержание витаминов снизилось: С – на 17%, В1 – на 36%, В2 – на 38%, В6 – на 36% в сравнении с контрольными образцами без органических примесей. Теоретически обоснован механизм взаимодействия белков, лактозы, витаминов восстановленной сыворотки с трихлорэтиленом и дихлорэтаном. Предложено для предотвращения снижения качества готового продукта воду, используемую для производства сывороточных напитков, подвергать дополнительной очистке от галогенорганических контаминантов. The stability of milk raw materials’ nutrients – proteins, lactose, vitamins C and B used in the production of whey beverages in the presence of priority organic contaminants – trichloroethylene, chloroform and dichloroethane, which have a toxic and carcinogenic effect and are formed during chlorination during water treatment in water used for the production of reduced and recombined dairy products was studied. The content of proteins and lactose in the reduced serum was determined by refractometry; water-soluble vitamins – by capillary electrophoresis; chloroform, trichloroethylene and dichloroethane – by gas-liquid chromatography. It was found that chloroform in water does not affect the safety of lactose, proteins and vitamins in the preparation of reduced whey. There was a decrease in the content of serum proteins prepared in water in the presence of trichloroethylene and dichloroethane by 11%, and lactose – by 32% in comparison with control samples produced in water without organic contaminants. Vitamin C content in the recovered whey in the presence of trichloroethylene has declined by 19%, vitamin B1 – 28%, vitamin B2 – 53%, vitamin B6 – 8%; for dichloroethane content of vitamin C decreased by 17%, vitamin B1 – 36%, vitamin B2 – 38%, vitamin B6 – 36% in comparison with control samples without organic impurity. The mechanism of interaction of proteins, lactose, and reduced serum vitamins with trichloroethylene and dichloroethane is theoretically justified. Therefore, to prevent a decrease in the quality of the finished product, the water used for the production of whey beverages must first be subjected to additional purification from organohalogen contaminants.

In this work the main analytical parameters for a spectrophotometric method of amino-acid analysis were determined.The Ringbom curve for L (+) Arginin (550 nm), L (-) Asparing (547 mn) and L (+) Lysin (547 mn) determination with o-diacetylbenzene showed different values for concentrations.The best rang of concentration was: L (+) Arginin 150 to 500µg/ml with a relative error of 5.26%; L (-) Asparagin 40 to 200µg/ml with relative error 1.43%; L (+) Lysin 8 to 44µg/ml with a relative error of 0.18%.Among the different compounds studied, it was observed the absorptions of the tiamin cloride (Vitamin B1), riboflavin choride (Vitamin B2), piridoxin cloride (Vitamin B6), carnitin, buclisin, folic acid and nicotinamide and that this compound in presence of o-diacetylbenzene do not interfere with the absorptions of the amino-acids L (+) Arginin, L (-) Asparagin and L (+) Lysin during their determination. On the other hand, the absorption of the compounds cianocobalamin and ɤ aminbutiric acid or the absorptions of these compounds in presence of o-diacetylbenzene interfere with absorptions of the aminoacids studied.The absorption spectra of these three pharmaceutical drugs was obtained with o-diacetylbenzene and we found out the possibility of their direct determination by the method described.

In this study, the content of vitamins and of toxic and beneficial (macro- and micro-) minerals in milk from yaks raised at different altitudes (3,215, 4,340, and 5,410 m) was investigated. For comparison, the components in cow’s milk were also measured. At higher altitudes, a significant ( P < 0.05 ) increase in vitamin A and vitamin E was observed in the yak’s milk, whereas the opposite was observed for vitamin B1 and vitamin B2. No significant statistical difference in vitamin C, Ca, P, Na, K, and Mg concentrations was observed in milk from yaks raised at different altitudes. The concentrations of Zn in milk from yaks raised at different altitudes showed no statistical difference, whereas the Mn and Fe concentrations in milk from yaks raised at 3,215 m were lower than those raised at higher altitudes. The concentrations of Pb and Cd in yak’s milk did not exceed the maximum permissible concentrations (Codex Alimentarius Commission), whereas their concentrations were higher in milk from yaks raised at 3,215 m than at higher altitudes. These findings indicated that the contents of vitamins and minerals in yak milk varied in different altitudes.

Abstract The aim of the present study is to develop a surface plasmon resonance sensor for the detection of vitamin B2, vitamin B9, and vitamin B12 in food samples by using the molecular imprinting technique. The vitamin B2, vitamin B9, and vitamin B12 imprinted and the non-imprinted surface plasmon resonance sensor chip surfaces were characterized by using contact angle measurements, atomic force microscopy, ellipsometry, and Fourier transform infrared-attenuated total reflectance. The real-time detection of vitamin B2, vitamin B9, and vitamin B12 was analyzed by using aqueous solutions in the concentration range of 0.01 ng/mL − 10 ng/mL for vitamin B2, 0.1 ng/mL − 8.0 ng/mL for vitamin B9, and 0.01 ng/mL − 1.5 ng/mL for vitamin B12. The limit of detection values was calculated as 1.6×10−4 ng/mL for vitamin B2, 13.5×10−4 ng/mL for vitamin B9, and 2.5×10−4 ng/mL for vitamin B12, respectively. Selectivity experiments were performed by using vitamin B1 and vitamin B6. The reproducibility of surface plasmon resonance sensors was investigated both on the same day and on different days for four times. Validation studies of the prepared surface plasmon resonance (SPR) sensors were performed by liquid chromatography-tandem mass spectrometry (LC-MS/MS).
