India is transiting to a knowledge society where the goal of business is changing. In this knowledge era business houses are concentrating on people, planet and profit that lead the path towards prosperity, sustainability. Sustainability is developing prosperity, without compromising the life of future generations. There are three pillars of sustainability: social, environmental, and economical. Today companies are integrating ideas of sustainability in their core functions to have business success. With see changes in the country’s economy new models of business is coming up. Companies are setting up that are more resilient and thrives in the long term. In a true sense a sustainable business model is a more accepted model in today’s business place that generates profit while improving societal and environmental conditions. This has given room for many new opportunities which in turn has given way to the fresh graduates to be more productive and contribute for the development of the organization as well as the nation. To meet the goals of sustainability and sustainable business there are many challenges the management graduates particularly needs to face. The development of a country is directly connected with quality education. The education system in India has to undergo a lot of reformation to produce competent students to match the requirements to drive sustainable development. Existing courses in Management Education needs to be more realistic to realize the needs of sustainability. Currently the success factor of Universities and Colleges is to produce graduates not just with the degree but in addition to it to produce competent prospective candidates for employment or entrepreneurs who can conduct themselves productively and efficiently in the dynamic economy and bring social change. This paper reports a literature-based analysis of the coverage of the competencies required for considering sustainability aspects for management graduates. The study aims to specify the required competencies for management students to become managers with regards to sustainability, and to provide guidance on how to close the competency gap.

α-Amylase has a wide range of applications in starch industries, i.e. baking, brewing, distillery, etc. The α-amylase production from Streptomyces erumpens MTCC 7317 immobilized cells was compared with that of free cells. The immobilized cells of S. erumpens in calcium alginate beads were more effective for production of α-amylase (12.2% more yield) than free cells. Response surface methodology (RSM) was used to evaluate the effect of main variables, i.e. incubation period, pH and temperature on enzyme production with immobilized cells. A full factorial Central Composite Design (CCD) was applied to study these main factors that affected α-amylase production. The experimental results showed that the optimum incubation period, pH and temperature were 36 h, 6.0 and 50°C, respectively for immobilized cells. Repeated batch fermentation of immobilized cells in shake flasks carried out in starch-beef extract medium showed that S. erumpens cells were physiologically active on the support even after four cycles of fermentation.

It is an imperative to find a proper way to maintain a balance between the economic development and natural environment’s carrying capacity, which is needed for the wellbeing and sustenance of human as well as non-human world. Balancing the economic growth and environmental quality has always been a challenge for business. In recent years, business has brought immeasurable wealth and prosperity. However, it has also caused unintended environmental degradation. Economic development is necessary to face the need of growing population but it should not add to a deteriorating environment. There is a need for broader ethical responses for environmental sustainability. The search for a sustainable future requires an integration of economic development with ethical objectives and scientific knowledge. Sustainability is a concept of continuance, relationships, and orientations. The paper deals with three interrelated ethical concepts, (1) corporate moral status, (2) corporate moral status to include human beings, (3) corporate moral status to include natural environment as a path of environmental sustainability.

Imperatyw nakazujący odnalezienie właściwego sposobu na utrzymanie równowago pomiędzy rozwojem ekonomicznym a pojemnością środowiska naturalnego jest niezbędny dla dobrostanu i trwania tak ludzkiego, jak i poza ludzkiego świata. Relacje pomiędzy wzrostem ekonomicznym a jakością środowiska stanowiły zawsze wyzwanie dla biznesu. Ostatnie lata oznaczały dla biznesu niemal niezmierzone bogactwo i dobrobyt. Zarazem doprowadzono do istotnej degradacji środowiska. Rozwój ekonomiczny jest niezbędny dla sprostania potrzebom rosnącej populacji ludzkiej, niemniej nie powinien pociągać za sobą ciągłego pogarszania się stanu środowiska. Niezbędne jest uwzględnienie etyki w dyskusji o zrównoważoności środowiskowej. Jeżeli przyszłość ma być zrównoważona, niezbędna jest integracja rozwoju ekonomicznego z nakazami etycznymi i wiedzą naukową. Zrównoważoność to koncepcja kontynuacji, budowania relacji i orientacji. W artykule przedstawiono trzy wzajemnie powiązane koncepcje etyczne: (1) status moralny korporacji, (2) status moralny korporacji uwzględniający człowieka, (3) status moralny korporacji uwzględniający środowisko naturalne jako drogę do zrównoważoności.

Strong sustainability defends that certain forms of natural capital (environment) are critical and therefore, non-substitutable. There is an increasing concern for conserving the natural environment due to its unique contribution for sustenance and wellbeing of all living beings. The development process which does not preserve its natural capital is bound to lead towards an unsustainable growth path. In the wake of strong sustainability, it is an imperative to preserve the natural environment as it is degrading beyond its threshold limit. The ethical aspect of strong sustainability raises the ethical question what is right thing to do and emphasizes on ethical relations of humans with natural environment. The paper defends strong sustainability from Kant’s Categorical Imperative. Categorical Imperative motivates every human to act out of duty. Actions done for the sake of duty alone are morally worthy. A duty is the relationship between one’s moral action and his autonomy of the will. Concerning the sustenance and wellbeing of the present and the future generation, it is the moral duty of the humans to preserve the natural environment.

PL

Silna zrównoważoność oznacza, że niektóre formy kapitału naturalnego (środowiska) są krytyczne i dlatego nie podlegają substytucji. Troska o ochronę naturalnego środowiska z uwagi na jego wyjątkowy udział w podtrzymywaniu i pomyślności wszystkich żywych stworzeń rośnie. Proces rozwojowy, który nie ochrania naturalnego kapitału oznacza wkroczenie na ścieżkę pozbawioną zrównoważenia. Podążając za silną zrównoważonością za imperatyw należy uznać ochronę środowiska naturalnego, które obecnie podlega degradacji przekraczającej próg akceptacji. Etyczny aspekt silnej zrównoważoności odnosi się do pytania co należy czynić i podkreśla znaczenie etycznych relacji pomiędzy ludźmi a ich środowiskiem naturalnym. Artykuł stanowi próbę obrony silnej zrównoważoności w oparciu o imperatyw kategoryczny Kanta. Motywuje on ludzi do podejmowania działań płynących z obowiązku. Takie działania określane są jako moralnie wartościowe. Obowiązek to relacja pomiędzy działaniami podejmowanymi przez jednostkę a autonomia woli. Biorąc pod uwagę postulat podtrzymania pomyślności obecnych i przyszłych pokoleń, moralnym obowiązkiem ludzi jest ochrona środowiska naturalnego.

This article proposes an algorithmic approach for multiple attribute group decision making (MAGDM) problems using interval-valued intuitionistic fuzzy soft matrix (IVIFSM) and confident weight of experts. We propose a novel concept for assigning confident weights to the experts based on cardinals of interval-valued intuitionistic fuzzy soft sets (IVIFSSs). The confident weight is assigned to each of the experts based on their preferred attributes and opinions, which reduces the chances of biasness. Instead of using medical knowledgebase, the proposed algorithm mainly relies on the set of attributes preferred by the group of experts. To make the set of preferred attributes more important, we use combined choice matrix, which is combined with the individual IVIFSM to produce the corresponding product IVIFSM. This article uses IVIFSMs for representing the experts’ opinions. IVIFSM is the matrix representation of IVIFSS and IVIFSS is a natural combination of interval-valued intuitionistic fuzzy set (IVIFS) and soft set. Finally, the performance of the proposed algorithm is validated using a case study from real life.

Studies of α-amylase production by Bacillus subtilis (CM3) isolated earlier from cow dung microflora, were carried out. The optimum temperature, pH and incubation period for amylase production were 50-70°C, 5.0-9.0 and 36 h, respectively. Enzyme secretion was very similar in the presence of any of the carbon sources tested (soluble starch, potato starch, cassava starch, wheat flour, glucose, fructose, etc.). Yeast extract and ammonium acetate (1%) as nitrogen sources gave higher yield compared to other nitrogen sources (peptone, malt extract, casein, asparagine, glycine, beef extract), whereas ammonium chloride, ammonium sulphate and urea inhibited the enzyme activity. Addition of Ca⁺² (10-40 mM) to the culture medium did not result in further improvement of enzyme production, whereas the addition of surfactants (Tween 20, Tween 40, Tween 80, and sodium lauryl sulphate) at 0.02% resulted in 2-15% increase in enzyme production. There were no significant variations in enzyme yield between shaked-flask and laboratory fermentor cultures. The purified enzyme is in two forms with molecular mass of 18.0 ± 1 and 43.0 ± 1 kDa in native SDS-PAGE.

Production and purification of α-amylase by probiotic Lactobacillus plantarum MTCC 1407 has been investigated under submerged fennentation using Mann Rogassa Sharpe medium containing (1%) soluble starch in lieu of glucose (2%) as carbon source. Response Surface Methodology was used to evaluate the effect of main variables, i.e. incubation period, pH and temperature on enzyme production. A full factorial Central Composite Design was applied to study these main factors that affected α-amylase production. The experimental results showed that the optimum incubation period, pH and temperature were 36 h, 7.0 and 35°C, respectively. The purified enzyme (by ammonium sulphate precipitation) had a molecular mass of 75 450 Da in SDS-PAGE.
