carotenoids are a large family of health-beneficial compounds that have been widely used in the food and nutraceutical industries. there have been extensive studies to engineer saccharomyces cerevisiae for the production of carotenoids, which already gained high level. however, it was difficult to discover new targets that were relevant to the accumulation of carotenoids.
neomycin production the fermentation profile of neomycin production in ssf varied with type of agro material used. highest antibiotic production (4567 µg/g substrate) was observed with apple pomace and the least (2765 µg/g substrate) with wheat bran. a 2-fold variation was noticed with these materials (fig 1).
the invention discloses a new process for preparing magnesium chloride hexahydrate by using high-magnesium brine, relating to the preparation process of magnesium chloride hexahydrate and solving the problems of high evaporation temperature, difficult separation of high temperature salt and high energy consumption in the traditional process for producing the magnesium chloride hexahydrate.

another mineral used for the magnesium production is carnallite. magnesium is also included in serpentine. oceans are a rich source of magnesium, which contain approx. 0.13% of the metal in the salt solution as mgcl 2 and mgso 4.
crystallizer crystallizers are machines used to convert wastewater into solid crystals and clean water. crystallization is a solid-liquid separation technique in which solid crystals are formed from a liquid solution. crystallizers can eliminate liquid wastes to create zero liquid discharge (zld). crystallization is divided into two stages: primary nucleation and secondary nucleation.
mgso 4: 1 – 3 kg/ton. temperatures and pressures oxygen is a low reactive oxidant. therefore, oxygen delignification requires elevated temperatures from 80°c to 120°c and pressures from 6 to 8 bars for increase reactions rate. however, an unacceptable degradation of carbohydrates is shown in case of high temperature above 120°c. naoh and ph
