Transformed microalgae capable of expressing glycosylated polypeptides and methods for producing said transformed microalgae and producing glycosylated polypeptides.

The invention relates to a rotary sonar fish finder. The rotary sonar fish finder comprises a base in the shape of a rotating body, and a sonar sensor is fixed to the bottom of the base. A water suction pump which is used for pumping water from bottom to top is further fixed to the bottom of the base. A centrifugal drainage plate which is coaxial with the base is connected to the upper portion of the base in a rotating mode. The centrifugal drainage plate comprises an axial water inlet, an internal water cavity and horizontal drainage channels from bottom to top, wherein the horizontal drainage channels are circumferentially and evenly distributed and are symmetrical in a rotating mode. The included angles formed between the drainage directions of outer ports of the drainage channels and the radius directions of the outer ports range from 45 degrees to 80 degrees. The rotary sonar fish finder enables sundries and duckweeds around the rotary sonar fish finder to be removed; meanwhile, the situation that the fish finder is wound by the duckweeds and algae can be effectively prevented.

The invention discloses a bamboo insect breeding feed. The feed comprises raw materials and auxiliary materials, wherein the raw materials comprise the components in percentage by mass: 10%-15% of bamboo sections, 20%-25% of bamboo shoot casings, 10%-20% of fresh bamboo shoot cores, and 10%-15% of corn flour; the auxiliary materials comprise the components in percentage by mass: 10%-15% of bone meal, 20%-25% of dried marine algae powder, 5%-7% of eggs, 10%-15% of yellow mealworm powder, 10%-15% of lactic acid bacteria and an appropriate amount of water. The bamboo insect breeding feed disclosed by the invention has the beneficial effects that the feed which is used as a daily feed of bamboo insects is good in palatability, can effectively promote appetite, increase the daily gain and strengthen the disease resistance; particularly, fresh bamboos are used as internal stuffing fillers, so that the habits and the characteristics that the bamboo insects gnaw the bamboos can be effectively improved, and the bamboo insects adapt to be fed with the feed step by step.

The invention belongs to the technical field of microorganisms, and particularly relates to an extracting method and an application of p-hydroxybenzoic acid. The extracting method comprises the following steps: inoculating the marine bacteria Arenibacter sp.6A1 into a fermentation culture medium, and carrying out fermentation culture to obtain a fermentation liquor; adjusting the pH value of the fermentation liquor to 3-4, and then carrying out extraction treatment to obtain an extract; and dissolving the extract, sequentially performing gel column chromatography and high performance liquid chromatography (HPLC) separation to obtain the p-hydroxybenzoic acid, wherein the HPLC separation conditions are as follows: gradient elution is carried out with a methanol/water mixed solvent, the detection wavelength is 254 nm, and the time of collecting liquid phase peaks is 25 min. Through the method, hydroxybenzoic acid with high purity and algae-dissolving activity is finally obtained, and a good foundation is laid for industrial production of hydroxyl benzoic acid.

The invention discloses a method for enhancing microalgae carbon sequestration and oil production by using diethanol amine. The method comprises the following steps: introducing CO2 into a microalgae culture system, and adding diethanol amine to enhance CO2 gas dissolution and mass transfer and stress microalgae oil production; by adding diethanol amine, the capacity of the algae liquid for storing carbon dioxide is firstly improved, and then the mass transfer process of dissolving carbon dioxide in the algae liquid from air is accelerated, so that the photosynthesis of microalgae is favorably improved, and the increase of microalgae biomass is accelerated; in addition, oil production metabolism can be promoted through stress of diethanol amine on microalgae cells, so that the oil content of the cells is increased. Through promotion of biomass and cell oil content, the final yield (oil yield = biomass * cell oil content) of microalgae oil is improved.

The invention herein describes a novel photobioreactor (PBR) system for culturing algae. The PBR system utilizes vertical transparent tubes that can be cyclically filled with an algae culture. The vertical tubes further feature pipe pigs deployed therein to disrupt formation of biofilm on the inner walls during the cyclic filling and emptying of the cultures.
