Inoculated carriers

Once the hapten has been designed and prepared, it is conjugated with a carrier protein to induce the best immunogenicity as possible to elicit an immune response in the animal (most commonly a mouse) in which it is inoculated. The antibodies produced by the defense mechanism of the adaptive immune system that specifically recognizes the hapten are then isolated, overproduced, and purified for testing their catalytic activity toward the targeted chemical reaction. 

In addition to ecological considerations concerning bacterial survival in soil, the relationship between desiccation sensitivity and mineral characteristics has relevance to carriers selected for the preparation of bacterial inocula (Kloepper Schroth, 1981 van Elsas Heijnen, 1990 Caesar Burr, 1991). Chao Alexander (1984) explored the potential use of soil-based inoculants for rhizobia. Pesenti-Barili et al. (1991) conducted a comprehensive survey of nine potential carriers for Agrobacterium radiobacter K84, including kaolinite and vermiculite, and concluded that vermiculite was most suitable.

The production of antibodies for small molecules is difficult to achieve as they must be coupled to a carrier protein before inoculation. Moreover, such conjugation may change the structural properties of the antigen exposed to the immune system and the obtained antibodies will be directed against a structure slightly different from the target compound. 

Place spore carrier in approximately 12 glass bottles located at the previously determined coolest area of the oven. Bottles adjacent to the inoculated bottles should contain thermocouples for monitoring purposes. 

The reactor was loaded with 75 ml granular carrier material [14], and finally, the entire reactor system, including tubing and recirculation reservoir, was autoclaved at 120°C for 30 min. Before use, the reactor system was gassed for 15 min with N2/CO2 (4 1) to ensure anaerobic conditions and filled with BA medium with an initial xylose concentration of 10 g/1. The reactor was started up in batch mode by inoculation with 80 ml of cell suspension with an optical density (OD578) of 0.9-1. The batch mode of operation was maintained for 24 h to allow cells to attach and to immobilize on the carrier matrix. After the batch run, the system was switched to continuous mode, applying a hydraulic retention time (HRT the volume of the reactor divided by the influent flowrate) of 8 h and up-flow velocity of 1 m/h. To achieve operational stability, the reactor was run for 7 days under... 

Erna Nemdy. In reading about development of the hepatitis B vaccine, ] Ema Nemdy learned that the first vaccine available for HBV, marketed in 1982, was a purified and inactivated vaccine containing HBV virus that had been chemically killed. The virus was derived from the blood of known HBV carriers. Later, attenuated vaccines were used in which the virus remained live but was altered so that it no longer multiplied in the inoculated host. Both the inactivated and the attenuated vaccines are potentially dangerous because they can be contaminated with live infectious HBV. 

Mushroom spawn is used to inoculate prepared substrates. This inoculum consists of a carrier material fully colonized by mushroom mycelium. The type of carrier varies according to the mushroom species cultivated, although rye grain is the choice of most spavwi makers. The history of the development of mushroom spawn ior Agaricus brunnescens culture illustrates how spawn production has progressed in the last hundred years.
