The shellfish waste which contains half of the amount of chitin can be efficiently transformed into useful products. Various approaches for the hydrolysis of chitin like physical, chemical, and enzymatic processes are there. Still, the use of enzyme chitinase is well documented as an effective and eco-friendly method. The present study summarizes the isolation of chitinase enzyme producing bacteria from different shrimp waste disposal sites in Parangipettai (India), and the possible use of an enzyme hydrolyzate as an immunostimulant to Asian Seabass (Lates calcarifer). The potential chitinase-producing bacteria were identified by 16S rRNA gene sequencing as Stenotrophomonas maltophilia. After purification, the chitinase specific activity was 5.01 (U/ml) and the protein content was 72 mg and the recovery rate was 48.06%. The optimum pH and te...

Методологическую основу исследования составляют идеи системного и ресурсного подходов. Область «системы воспитания» в теории воспитания недостаточно изучена по сравнению с «воспитательной системой». Элементы системы воспитания: взгляды педагогического коллектива на новые смыслы воспитания; система воспитательной деятельности классного руководителя; система инновационных ресурсов для обеспечения развития воспитания; проектное и ресурсное управление процессами изменений. Ресурсное развитие системы воспитания в школе предполагает определенную последовательность этапов: поисковый, структурный, системный, ресурсный. Для развития системы воспитания необходимо достижение ее ресурсного состояния, связанного с наличием инновационных ресурсов. Затруднениями педагогов являются: дефицит научных разработок по методике формирования мировоззренческих, гражданских и нравственных идеалов школьников; управление в школе направлено не на развитие воспитания, а на функционирование учреждения; инфраструктура школы не ориентирована на ресурсное обеспечение развития системы воспитания. Условием развития системы воспитания становится инновационное педагогическое проектирование. Этот метод опережающего управления позволяет любое изменение в системе воспитания рассматривать как локальную систему. Ключевые слова: системный подход, ресурсный подход, система воспитания, подсистема, системные изменения, ресурсное развитие.

Článek podává přehled terminologického i věcného uchopení té části agendy vedení škol, jež se vztahuje k procesům a výsledkům učení, vychází při tom z domácí a anglicky psané zahraniční literatury. Odlišnosti v terminologii mohou být odrazem hlubších rozdílů v pojetí cílů školního vzdělávání i v chápání úkolů vedoucích pracovníků. Ukazuje se, že česká pedagogická teorie i praxe zatím věnovaly jen malou pozornost přístupům, které jsou v zahraničí označovány termínem instructional leadership.

Methods: Fresh marine seaweeds Gracilaria edulis, Kappaphycus spicifera, Sargassum wightii (S. wightii) were collected. Each seaweed was extracted with different solvents. In the study, test pathogens were collected from microbial type culture collection. Antibacterial activity was carried out by using disc diffusion method and minimum inhibition concentration (MIC) was calculated. Best seaweed was analysed by fourier transform infrared spectroscopy. The cured extract was separated by thin layer chromatography (TLC). Fraction was collected from TLC to check the antimicrobial activity. Best fraction was analysed by gas chromatography mass spectrometer (GCMS). Results: Based on the disc diffusion method, S. wightii showed a better antimicrobial activity than other seaweed extracts. Based on the MIC, methanol extract of S. wightii showed lower MIC than other solvents. S. wightii were separated by TLC. In this TLC, plate showed a two fraction. These two fractions were separated in preparative TLC and checked for their antimicrobial activity. Fraction 2 showed best MIC value against the tested pathogen. Fraction 2 was analysed by GCMS. Based on the GCMS, fraction 2 contains n-hexadecanoic acid (59.44%). Conclusions: From this present study, it can be concluded that S. wightii was potential sources of bioactive compounds.

Mutualism is an association among several species where all of them are benefited from this association [10]. Sometimes, it can be an obligatory relation involving close physical and biochemical contact between two organisms, such as those between plants and mycorrhizal fungi [5, 7]. Commensalism is also a symbiotic interaction between two living organisms, where one organism benefits and the other is neither harmed nor benefited [11]. Biological interactions in which the population ...

Notably, the rise in shellfish industries contributes to tons of shellfish waste composed of up to 58% chitin. Chitin, the second most ample polymer next to cellulose, is insoluble and resistant to degradation. It requires chemical-based treatment or enzymatic hydrolysis to cleave the chitin polymers. The chemical-based treatment can lead to environmental pollution, so to solve this problem, enzymatic hydrolysis is the best option. Moreover, the resulting biopolymer by-products can be used to boost the fish immune system and also as drug delivery agents. Many marine microbial strains have chitinase producing ability. Nevertheless, we still lack an economical and highly stable chitinase enzyme for use in the industrial sector. So we isolate a novel marine bacterial strain Achromobacter xylosoxidans from the shrimp waste disposal site using...
