Pemanfaatan sumberdaya perairan di teluk Hurun saat ini masih sangat potensial. Salah satu pemanfaatan sumberdaya perairan yaitu optimalisasi alat tangkap bubu lipat yang ekonomis dan ramah lingkungan. Penerapan alat tangkap ini diharapkan dapat memberikan gambaran potensi rajungan yang ada di teluk Hurun. Materi yang digunakan yaitu bubu lipat dan perlengkapan penangkapan lainnya. Penggunanaan alat tangkap bubu lipat menghasilkan tangkapan rajungan sebesar 88,98 kg (market size) dan 16,82 kg (under size) dengan jumlah yang diperolah masing-masing yaitu 916 ekor (market size) dan 358 ekor (under size).

Netflix and other transnational online video streaming services are disrupting long-established arrangements in national television systems around the world. In this paper we analyse how public service media (PSM) organisations (key purveyors of societal goals in broadcasting) are responding to the fast-growing popularity of these new services. Drawing on Philip Napoli’s framework for analysing strategic responses by established media to threats of competitive displacement by new media, we find that the three PSM organisations in our study exhibit commonalities. Their responses have tended to follow a particular evolution starting with different levels of complacency and resistance before settling into more coherent strategies revolving around efforts to differentiate PSM offerings, while also diversifying into activities, primarily across new platforms, that mimic SVoD approaches and probe production collaborations. Beyond these similarities, however, we also find that a range of contextual factors (including path-dependency, the role and status of PSM in each country, the degree of additional government support, cultural factors and market size) help explain nuances in strategic responses between our three cases.

Natural flavor and fragrance market size is expected to grow steadily due to the rising consumer demand of natural ingredients. This market request is guided by the general opinion that the production of natural compounds leads to a reduction of pollution, with inherent advantages for the environment and people’s health. The biotransformation reactions have gained high relevance in the production of natural products. In this context, few pieces of research have described the role of microalgae in the oxidation of terpenoids. In this present study, we questioned the role of microalgal based oxidation in the synthesis of high-value flavors and fragrances. This study investigated the role of three different microalgae strains, Chlorella sp. (211.8b and 211.8p) and Chlorococcum sp. (JB3), in the oxidation of different terpenoid substrates: α-ionone, β-ionone, theaspirane and valencene. Unfortunately, the experimental data showed that the microalgal strains used are not responsible for the substrate oxidation. In fact, our experiments demonstrate that the transformation of the four starting compounds is a photochemical reaction that involves the oxygen as oxidant. Even though these findings cast a shadow on the use of these microorganisms for an industrial purpose, they open a new possible strategy to easily obtain nootkatone in a natural way by just using an aqueous medium, oxygen and light.
