Biopulping has the potential to improve pulp quality, paper properties and to reduce energy costs and environmental impact relative to traditional pulping approaches. The technology has focused on the white rot fungi that are known to be degrader of wood constituents. This group of fungi have complex extracellular ligninolytic enzyme systems that can selectively degrade/ alter lignin structure and allow cellulose fibres to be relatively unaffected. It colonizes either on living or dead wood and decomposes almost all plant cell wall polymers including lignin and extractives making it to be extremely potential to be used in biopulping. Biopulping reduces the chemical load in paper industry and thus partially limiting environmental threats caused by conventional pulping. It has been advised that energy savings alone could make the process economically viable. Other benefits include improved burst strength and tear indices of product and reduced pitch deposition.

Indeed, there are great market potential of Aloe vera (L.) Burm.f. (Ghrit-kumari) due to their medicinal and cosmetic values. However, the serious problems faced by farmers related to supply of harvested leaves materials after cultivation for industrial extraction and production of juice under a short and specific time of transportation to avoid spoil of materials and protect from decayed condition of leaves. Hence, the cultivation practices of the plant are not being popular although the utilization of leaves by pharmaceutical companies is gradually increasing. To solve the above problems, an analysis on extraction of pulp from leaves and preparation of juice in a small scale level has been carried out useful for the farmers and medicinal plant growers for processing of leaves at plantation site. It has been observed that after harvesting of leaves the boil or warm water is useful to process the leaves for pulp extraction in cold season. The standard percentage of activated charcoal observed in processing of pulp for removal of pigments varies from 12-15 gm/ kg according to pulp. The processing in homogenization, filtration and better preservation and stability of juice different ratio have been analyzed for keeping in good condition up to 180 days and above and the requirement of EDTA is 0.9-1.2gm/kg of pulp. The citric acid required 1.1-1.3 gm/kg for better and good condition of juice. The maintenances of PH of processed material various composition of different preservatives have been assessed. Effects of natural preservatives like lemon and honey to protect juice up to 30 days has been studied and found at least 10:5 ml/100ml respectively in closed container under good storage condition.

Sweet basil is an incredible herb, used both as a classic culinary and ornamental herb of Home Gardens. The genus Ocimum contains approximately 65 species of herbs and shrubs originated in tropical Asia. It has a strong medicinal use and it is very high in vitamins and minerals. The present study holds 6 varieties of Ocimum basilicum L. consisting of 29 accessions were procured from National Gene Bank, New Delhi. These accessions were grown in the Kharif seasons of 2014-15 at ICAR-NBPGR Regional Station, Bhowali, Nainital Uttarakhand for analysing of their quantitative and qualitative or phenotypic characters for identification of superior genotypes. The comparative study of Ocimum spp. was examined to assess the variability of qualitative and quantitative morphological characters using standardized description present among 30 accessions of 6 varieties of Ocimum basilicum L. (Sweet Basil).

The type or nature of leaf is usually characteristic of a species (monomorphic), although some species produce more than one type of leaf (dimorphic or polymorphic). Some plants have small changes in leaf size and growth habit between juvenile and mature stage (Homoblasty), while some other species have marked changes in leaf shape and growth habit between juvenile and mature stages (Heteroblasty). In Coscinium fenestratum (Gaertn.) Colebr., as a part of seed biology studies, a number of seedlings were raised from the same seed sample which is from the same mother plant. Among the seedlings, 5-10% of the seedlings showed remarkable variations on leaf shape in their juvenile stage. Since leaf shape and allied morphological characters are significant for demarcating Coscinium fenestratum from similarly looking Anamirta cocculus (L.) Wight. & Arn. and Diploclisia glaucascens (Blume.) Diels. of the same family Menispermaceae, documenting the leaf characters of seedling and mature plants deserve unique attention.
