Proteomic characterization and schizophyllan production by Schizophyllum commune ISTL04 cultured on Leucaena leucocephala wood under submerged fermentation

Broussonetia papyrifera is an exotic tree widely grown for paper production. Due to its prolific regeneration it has invaded forestcanopy gaps and degraded farmlands and has now become an invasive species in Ghana. In enhancing its value for use the plantwas evaluated as potential forage for grazing animals vis-à-vis other two existing forage plants: Ficus exasperata and Leucaenaleucocephala.The study assessed the palatability and preference of Broussonetia papyrifera using sheep and goats for the wet anddry seasons.The species were assessed in indoor pen feeding trials using eight-unit (3×3 m) pens with the cafeteria method.The amount of forage offered was 100g (fresh material) in all instances for each species and for ten minutes. Adesign basedon 3×2×2 factorial in Randomized Complete Block Design (RCBD) was used to test the differences in palatability betweenthe three forage species.Results revealed that palatability was higher (P<0.05) in Leucaena leucocephala compared with Ficusexasperata and Broussonetia papyrifera for sheep and goats across seasons. The trend shown might be the result of the effectsof familiarity with the Leucaena leucocephala since animals tend to select plants that are familiar than newly introduced andunfamiliar plants. The study also revealed high level of condensed tannin (CT) in Broussonetia papyrifera which might haveinterfered with forage intake by the animals.There were no significant differences in palatability of Broussonetia papyrifera forgoat in both dry and wet season interactions and Ficus exasperata for goat in both dry and wet season interactions (P>0.05).Thestudy concluded that Broussonetia papyrifera could be a potential feed for both sheep and goats across seasons.The researchrecommended that livestock farmers should incorporate Broussonetia papyrifera feed into their programmes for both sheep andgoats and should be introduced to animals from infancy so that it may become a familiar feed for them.

Diabetes Melitus

Diabetes melitus merupakan suatu penyakit dengan adanya gangguan sekresi insulin baik karena penurunan sensitifitas maupun kerusakan pada sel beta. Tujuan penelitian ini adalah membuktikan ekstrak daun petai cina (Leucaena leucocephala (Lam.) de Wit) memiliki aktivitas menurunkan kadar gula darah mencit hiperglikemik pada dosis yang efektif. Penelitian antihiperglikemik ini menggunakan mencit putih sebanyak 30 ekor. Pengujian aktivitas antihiperglikemik dilakukan pada 6 kelompok perlakuan yaitu kelompok I (kontrol normal), kelompok II (kontrol negatif, induksi aloksan 200 mg/kg BB dan akuades), kelompok III (induksi aloksan dan glibenklamida 10 mg/kg BB), kelompok IV (induksi aloksan dan ekstrak daun petai cina 200 mg/kg BB), kelompok V (induksi aloksan dan ekstrak daun petai cina 400 mg/kg BB), kelompok VI (induksi aloksan dan ekstrak daun petai cina 300 mg/kg BB). Semua kelompok perlakuan diberikan perlakuan tersebut selama 14 hari dan dilakukan pengukuran kadar gula darah pada hari ke-0, 3, 10, dan 17. Aktivitas antihiperglikemik ekstrak daun petai cina ditunjukkan dengan cara menghitung daya hipoglikemik masing-masing perlakuan. Hasil penelitian menunjukkan bahwa ekstrak etanol daun petai cina mempunyai aktivitas antihiperglikemik pada mencit yang diinduksi aloksan. Pada dosis uji ekstrak etanol daun petai cina 600 mg/kg BB mempunyai aktivitas antihiperglikemik yang efektif dibanding dengan dosis 400 mg/kg BB dan 200 mg/kg BB yang sebanding dengan kelompok kontrol positif.
