Distribution of galling insects and their parasitoids on Caryocar brasiliense tree crowns / Distribuição de insetos galhadores e seus parasitoides em copas de pequizeiros (Caryocar brasiliense)

Caryocar brasiliense Camb. (Malpighiales: Caryocaraceae) is widely distributed in the Brazilian savanna and its fruits are used by humans for food, production of cosmetics, lubricants, and in the pharmaceutical industry. This plant is damaged by galling insects. Number of these galling insects and their parasitoids was recorded, in the field (galls) and in the laboratory (adults emerged from the galls), from three C. brasiliense crown heights, during three years. Numbers of adults of Eurytoma sp. (Hymenoptera: Eurytomidae), galling insect (younger attack) and Sycophila sp. (Hymenoptera: Eurytomidae) (a parasitoid of Eurytoma sp.), were greater on the apical parts of C. brasiliense tree crowns. Numbers and groups of Eurytoma sp. globoid galls (older attack) were higher in the median and basal crown parts. The numbers of Eurytoma sp. galls were higher on apical part of C. brasiliense tree crown and also of their parasitoids.

(Malpighiales: Caryocaraceae) é, amplamente, distribuída no cerrado brasileiro e seus frutos são utilizados para alimentação humana, produção de cosméticos, lubrificantes e na indústria farmacêutica, no entanto, é danificada por insetos galhadores. O número de insetos galhadores e seus parasitoides foram avaliados, em campo (galhas) e em laboratório (emergência de adultos das galhas), em três alturas do dossel de C. brasiliense, durante três anos. Os números de adultos Eurytoma sp. (Hymenoptera: Eurytomidae), inseto galhador (galhas novas) e de Sycophila sp. (Hymenoptera: Eurytomidae), parasitoide de Eurytoma sp., foram maiores na parte apical do dossel da copa de árvores de C. brasiliense. A quantidade de galhas globoides de Eurytoma sp., isoladas ou em grupo (galhas velhas), foi maior na parte mediana e basal da copa. Os números de adultos do galhador Eurytoma sp. e de seus parasitoides, que os seguem, foram maiores na parte apical da copa de árvores de C. brasiliense.

Aqueous two-phase extraction as a platform in the biomanufacturing industry: economical and environmental sustainability.

The biotech industry is, nowadays, facing unparalleled challenges due to the enhanced demand for biotechnology-based human therapeutic products, such as monoclonal antibodies (mAbs). This has led companies to improve substantially their upstream processes, with the yield of monoclonals increasing to titers never seen before. The downstream processes have, however, been overlooked, leading to a production bottleneck. Although chromatography remains the workhorse of most purification processes, several limitations, such as low capacity, scale-related packing problems, low chemical and proteolytic stability and resins' high cost, have arisen. Aqueous two-phase extraction (ATPE) has been successfully revisited as a valuable alternative for the capture of antibodies. One of the important remaining questions for this technology to be adopted by the biotech industries is, now, how it compares to the currently established platforms in terms of costs and environmental impact. In this report, the economical and environmental sustainability of the aqueous two-phase extraction process is evaluated and compared to the currently established protein A affinity chromatography. Accordingly, the ATPE process was shown to be considerably advantageous in terms of process economics, especially when processing high titer cell culture supernatants. This alternative process is able to purify continuously the same amount of mAbs reducing the annual operating costs from 14.4 to 8.5 million (US$/kg) when cell culture supernatants with mAb titers higher than 2.5 g/L are processed.

Aqueous two-phase systems: A viable platform in the manufacturing of biopharmaceuticals.

The number of biotechnology-based pharmaceuticals in the late-stage pipeline has been increasing more than ever. As a result, there is an enhanced demand for more efficient and cost-effective processes. During the last years, the upstream technology for the production of biopharmaceuticals has been considerably improved. Continuous discoveries in molecular biology and genetics, combined with new advances in media and feed development, have significantly increased the production titres. In order to keep up this gain, it is now essential to design new, as well as to improve the existing downstream processes that remain an unresolved bottleneck. This review evaluates several alternatives to the currently established platforms for the downstream processing biopharmaceuticals, with main focus on aqueous two-phase extraction.
