The supply of minerals in the medium is an essential part of plant tissue culture systems. Currently used media are largely based on empirical modifications to a few basic formulations. Optimum requirements vary widely between plant genotypes and culture systems and, as yet, it is not possible to predict the mineral requirements of untried species. A more mechanistic approach is presented which may improve this situation. Published literature and some current research aimed at a better understanding of the process of mineral nutrition in vitro are reviewed.

The endogenous bacterial contamination of plant tissue culture materials and their possible control was studied. Nine bacterial isolates were isolated from the contaminated tissue culture materials viz. potato and tea. On the basis of morphology and biochemical characters of nine isolates, seven were identified as Gram positive belonging to Bacillus alcalophilus, B. circulans, B. infantis, B. lentus, B. schlegelii, B. pumilus and B. subtilis. Remaining two were Gram negative and identified as Enterobacter cloacae sub. sp. dissolvens and Pantoea agglomerans. Molecular analysis was conducted on the basis of 16S rDNA sequence to confirm three isolates. Culture and sensitivity test was carried out to screen out the antibiotic sensitivity where streptomycin (S-10), polymyxin (PB-300) and gentamicin (CN-120) antibiotics were found to be effective against all bacterial isolates. The culture and sensitivity test reflected the feasibility to control or eliminate the contaminant bacteria during in vitro culture of plant which is very much required in the commercial tissue culture production.Plant Tissue Cult. & Biotech. 28(1): 99-108, 2018 (June)

Capsaicin, a secondary metabolite produced in capsicum, is in high demand in pharmaceutical industry because of its various medicinal properties. Currently, the supply of capsaicin depends upon its extraction from capsicum fruits. This limits the production of capsaicin as it depends upon agricultural produce. The current review has compiled information from various literature published on chemistry and importance of capsaicin along with its method of production. It also reviews the process of in vitro production of capsaicin through plant tissue culture, strategies of increasing capsaicin accumulation and its advantages over extraction from fruits and artificial synthesis.

Autoclaving nutrient media is still considered as the optimum mode of sterilisation in plant cell and tissue culture. During the process steam under high pressure is maintained at 120 degrees Celsius, 15 psi for 15-20 minutes in a chamber, optimised to kill all possible microbial life forms. But the disadvantages related to the process of autoclaving are plentiful. They are, decrease in the media pH, salt precipitation, agar depolymerisation, carbohydrate hydrolysis, volatile obliteration and necessity of the infrastructure investment. Requirements of additional resources (time, human resources, electrical energy) have forced the lookout for a more viable alternative, that is, chemical sterilisation. The use of Sodium dichloroisocyanurate (NaDCC) is a useful alternative for media and explant sterilisation. NaDCC is stable, water-soluble, non-toxic and easy to use at room temperature, does not have any environmental hazards and is not phytotoxic. The use of NaDCC as a disinfectant has been documented well concerning water sterilisation, surface sterilisation and also as a broad spectrum disinfecting agent. Disinfecting property of NaDCC is due to the hydrolytic release of chlorine, and this can be utilised for sterilisation of media and explants in plant tissue culture. NaDCC is a useful alternative for autoclaving at a concentration range of 0.05 to 1.0 g/l. However, only a few reports are available for its use as a sterilising agent for media and explants for in vitro cultures of plants. This paper discusses and reviews the possibility of establishing NaDCC as an active agent for explant sterilisation and as a viable alternative to medium sterilisation through autoclaving.
