Dari total 13 spesies Moringa, di Saudi Arabia hanya terdapat dua spesies, yaitu M. peregrina dan M. oleifera. Kedua spesies ini memiliki kandungan nutrisi dan bahan obat yang tinggi serta mampu bertahan pada iklim kering. Biotipe Moringa baru yang berbeda dengan kedua spesies ini telah teramati di daerah Al Bahah, Saudi Arabia. Pada penelitian ini, karakterisasi dari biotipe baru ini telah dilakukan dengan mengamati 22 karakter kualitatif dan kuantitatif dari daun, biji dan bunga. Semua karakter ini kemudian dibandingkan dengan M. peregrina dan M. oleifera untuk mengetahui hubungan biotipe baru dengan kedua spesies. Hasil pengamatan pada karakter kualitatif menunjukan bahwa biotipe baru ini memiliki 8 karakter (tepi anak daun, warna bunga, bentuk kelopak dan mahkota bunga, perlekatan kelopak bunga, warna dan orientasi kepala sari, dan bentuk dasar  bunga) yang sama dengan kedua spesies, satu karakter (distribusi warna merah pada perhiasan bunga) dengan M. peregrina  saja, tiga karakter (tipe susunan anak daun, kulit biji dan sayap biji) dengan M. oleifera saja. Untuk karakter-karakter kuantitatif, hasil pengukuran menunjukan semua karakter pada biotipe baru berada pada posisi antara M. peregrina and M. oleifera. Berdasarkan hasil ini, kami menyimpulkan bahwa biotipe baru dari Moringa ini adalah hibrid hasil persilangan M. peregrina dan M. oleifera.Kata kunci: biotipe, bunga, Moringa peregrina; Moringa oleifera, daun, biji.

Moringa oleifera Lam. (moringa) is a tree species with the potential for use in biofuel production. However, knowledge regarding the morphology and physiology of its seeds is needed to establish field production. The goals of the present study were to investigate the internal morphology of seeds by X-ray and to identify the fungal microorganisms present in the seeds. Two hundred seeds from two trees were analyzed. The morphological characterization of the seeds was performed using an X-ray chamber with an X-ray source operated at 22 kV for 14.8 s. The fungi were identified using the blotter test. The seeds were characterized as (a) full and well formed, (b) with internal space and poorly formed and (c) stained or damaged. The malformed seeds with an internal space showed the highest incidence (55%). The results indicated that X-ray tests are valid for the internal characterization of moringa seed morphology. The fungi Aspergillus niger, Aspergillus flavus, Alternaria sp., Fusarium sp., Penicillium sp. and Phomopsis sp. occurred in moringa seeds.

Objective: to characterize the seeds of Moringa oleifera present in various crops in Mexico morphologically. Design / Methodology / Approach: An analysis of variance, principal components, and conglomerates of qualitative morphological descriptors (shape, color, presence of wings and wing color) and quantitative (length, width, and weight) were carried out. Results: Significant statistical differences (P˂0.05) were found in the seeds' length, width, weight, and almonds. The principal component analysis indicated that components 1 (70.58%) and 2 (25.59%) contributed 96.17% of the variation, and the cluster analysis identified four groups. The evaluated populations showed qualitative variation (shape, color, presence of wings, and color of wings) and quantitative (length, width, and weight). Study limitations/implications: the germination percentage could not be evaluated because no information was obtained on the age of the seed and the storage conditions. Result/Finding:Conclusion: This information enriches the knowledge of Moringa oleifera in Mexico and serves as a basis for selecting materials of most significant interest.

Mycobacteriophage R1 was originally isolated from a lysogenic culture of M. butyricum. The virus was propagated on a leucine-requiring derivative of M. smegmatis, 607 leu−, isolated by nitrosoguanidine mutagenesis of typestrain ATCC 607. Growth was accomplished in a minimal medium containing glycerol and glucose as carbon source and enriched by the addition of 80 μg/ ml L-leucine. Bacteria in early logarithmic growth phase were infected with virus at a multiplicity of 5, and incubated with aeration for 8 hours. The partially lysed suspension was diluted 1:10 in growth medium and incubated for a further 8 hours. This permitted stationary phase cells to re-enter logarithmic growth and resulted in complete lysis of the culture.

The different integrated production systems can directly interfere with its bacterial community. The present study aimed to assess density, bacterial diversity and the influence of dry and rainy season in different integrated and an exclusive production system. The fallow and a native forest area was assessed to. Samples were collected in 2012 March and September. The isolation were carried out into Petri dishes containing DYGS medium. The number of colony forming units (CFU) was counted after 48 hours and. The bacterial density ranged between 106 and 107 CFU g-1 soil. The crop system affected the dynamics of the bacterial community only in the rainy season. The rainy season showed greater density of total bacteria when compared to the dry period regardless of the cropping system. The dendrograms with 80 % similarity showed thirteen and fourteen groups in the rainy and dry seasons. Isolates with the capacity to solubilize phosphate in vitro were obtained from all areas in the two seasons, but this feature has been prevalent in bacteria isolated during the rainy season

Background: Endophytic fungi live in plants’ tissue and can produce the same bioactive compounds as its host plant produces. Syzygiumpolyanthum leaves have known to be one of the antibacterial compound producers. Aim and Objective: This study aimed to characterize morphologically, microscopically, and molecularly the antibacterial-producing endophytic fungi of Syzygiumpolyanthum leaves. Methods: The isolation of endophytic fungi was done by fragment planting method on PDA medium. The antibacterial screening was performed using the antagonistic test as the first screening followed by the disc diffusion test method. The morphological characterization was based on isolate’s mycelia color, growth pattern, margin, and surface texture of the colony, while the microscopic characterization was based on its hyphae characteristics. The molecular characterization of the isolate was done by nitrogen base sequence analysis method on nucleotide constituent of ITS rDNA genes of the isolate. Results: The results found that isolate DF1 has antibacterial activity against E.coli, S.aureus, P.acne, and P.aeruginosa, with the greatest inhibition at 10% concentration of broth fermentation extract on S.aureus with a diameter of inhibition of 13.77 mm. Conclusion: Based on macroscopic, microscopic, and molecular characterization, DF1 isolate is similar to Ceriporialacerate.

In the current work, the characterization of novel chitosan/silica nanoparticle/nisin films with the addition of nisin as an antimicrobial technique for blueberry preservation during storage is investigated. Chitosan/Silica Nanoparticle/N (CH-SN-N) films presented a stable suspension as the surface loads (45.9 mV) and the distribution was considered broad (0.62). The result shows that the pH value was increased gradually with the addition of nisin to 4.12, while the turbidity was the highest at 0.39. The content of the insoluble matter and contact angle were the highest for the Chitosan/Silica Nanoparticle (CH-SN) film at 5.68%. The use of nano-materials in chitosan films decreased the material ductility, reduced the tensile strength and elongation-at-break of the membrane. The coated blueberries with Chitosan/Silica Nanoparticle/N films reported the lowest microbial contamination counts at 2.82 log CFU/g followed by Chitosan/Silica Nanoparticle at 3.73 and 3.58 log CFU/g for the aerobic bacteria, molds, and yeasts population, respectively. It was observed that (CH) film extracted 94 regions with an average size of 449.10, at the same time (CH-SN) film extracted 169 regions with an average size of 130.53. The (CH-SN-N) film presented the best result at 5.19%. It could be observed that the size of the total region of the fruit for the (CH) case was the smallest (1663 pixels), which implied that the fruit lost moisture content. As a conclusion, (CH-SN-N) film is recommended for blueberry preservation to prolong the shelf-life during storage.
